Definitions
- the present invention relates to a method for producing melted bodies, comprising the production of a melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid in a first container; Mixing the melt dispersion thus obtained with at least one aesthetic agent in a subsequent container and shaping the melt dispersion thus obtained to obtain solid lozenges. Also disclosed are the melting bodies produced by this method, a detergent or cleaning agent containing them, the use of such a detergent or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a washing or cleaning agent.
- the treated object such as the laundry in particular, often only gives off a faint scent, which then becomes weaker and weaker after a short time.
- the pleasant feeling of freshness of the treated object disappears after a short time.
- Fragrances in the form of fragrance pastilles are often used either as an integral part of a washing or cleaning agent, or are metered into the washing drum in a separate form directly at the start of a wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosing.
- Such scent pastilles are usually made from melt dispersions, the main component of which is a water-soluble or water-dispersible carrier material with a suitable melting point.
- a suitable melting point e.g., a water-soluble or water-dispersible carrier material with a suitable melting point.
- solids can also be added to such melt dispersions in order, for example, to influence the viscosity of the dispersion to be processed.
- the production of the pastilles requires the continuous supply of such a melt dispersion.
- the melt dispersion is naturally provided at temperatures above room temperature, the absolute temperature of the melt dispersion being determined by the chemical
- the nature of the carrier material is determined as well as by the further course of the process, for example the use of additional heating or cooling elements provided or not provided in the course of the process.
- the elevated temperature of the melt dispersion can affect the chemical integrity of the active substances and auxiliaries used and/or the physical integrity of the substance system used, for example its storage stability.
- this object was achieved by a method which comprises at least three separate, successive method steps, so that an uninterrupted production process is provided.
- the present invention is directed to a fusible body made by a method as described herein.
- the present invention also relates to the use of the melting bodies, produced by a process as described herein, as textile care agents, preferably scenting agents and/or fabric softeners, for scenting and/or conditioning textile fabrics.
- the present invention further relates to a detergent or cleaning agent, comprising a melt body, produced by a method as described herein.
- Melt bodies designates bodies that are non-porous, meltable, water-soluble or water-dispersible under standard conditions (20° C., 1013 mbar) as solids and can be obtained by solidification and reshaping of the melts described herein.
- the melting bodies can have any shape.
- the shaping takes place in particular in step iii) of the method described. Solid, particulate are preferred
- Shapes such as essentially spherical, figurative, scaly, cuboid, cylindrical, conical, spherical cap or lens, hemispherical, disc or needle-shaped melted bodies.
- the melted bodies can have a figured configuration resembling a gummy bear. Due to their assembly properties and their performance profile, hemispherical melting bodies are particularly preferred.
- Preferred melted bodies have a maximum diameter of between 4 and 15 mm, preferably between 5 and 10 mm, in any spatial direction. Particularly preferred melted bodies are characterized by a maximum diameter of 2 to 8 mm, particularly preferably 4 to 6 mm. On the one hand, such melted bodies are particularly readily water-soluble and, on the other hand, have a size that is visually appealing to the consumer.
- 100% hemispherical (hemispherical) particles are characterized by a height to diameter ratio of 0.5.
- those melted bodies which have a height-to-diameter ratio of 0.25 to 0.49 are also referred to as hemispherical.
- Particularly preferred are melted bodies with a height-to-diameter ratio of 0.35 to 0.45.
- the weight of the individual melted bodies is usually between 2 and 150 mg, preferably between 5 and 10 mg.
- Water-soluble as used herein means a solubility in water at 20°C of at least 1 g/L, preferably at least 10 g/L, more preferably at least 50 g/L.
- Water-dispersible as used herein means that the carrier material can be dispersed in water at a temperature of 20°C using known methods.
- At least one refers to 1 or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this information relates to the nature of the agent/compound and not to the absolute number of molecules. "At least one fragrance” therefore means that at least one type of fragrance is detected, but it can also contain 2 or more different types of fragrance.
- the present invention relates to a manufacturing method for melted bodies, such as scented pastilles, in which a melted dispersion is produced in an uninterrupted process sequence and shaped in a final step.
- the method as described here is characterized in that product changes, i.e. changing the composition of the melt dispersion, for example by using a different fragrance and/or color component, are possible without great effort, and it is also possible to largely avoid the accumulation of salable product quantities.
- Another advantage of the method as described here is that the temperature-sensitive aesthetics incorporated into the melt dispersion to be produced has a short residence time at elevated temperatures (corresponding to the melting temperature of the respective carrier material) compared to production methods known in the prior art, which lozenges produced by the process as described herein show an improved color effect and/or an improved fragrancing upon their use.
- a first object of the present invention is therefore a method for the production of melted bodies.
- the method comprises the steps described below:
- a perfume-free melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid is produced in a first container.
- the water-soluble or water-dispersible molten carrier material used has a melting point of >30°C, preferably >40°C and in particular >50°C.
- Containers suitable for this purpose are generally known to those skilled in the art. However, a prerequisite for the applicability in a method as described here is that the container enables thorough mixing of the components of the melt dispersion to be produced in step i) and also comprises at least one adjustable opening through which the components of the melt dispersion to be produced in step i) in can be introduced into the container, and additionally at least one further adjustable opening through which the melt dispersion produced in step i) can be discharged from the container. Inlet and/or outlet flow can be volume-controlled via these openings.
- the first container can be a mixing unit, for example.
- the components of the melt are heated to a temperature above the melting point of the carrier material, preferably to a temperature above 40°C, more preferably above 50°C.
- the carrier material can already be supplied in molten form and mixed with the at least one solid in the first container.
- the transfer of the melt dispersion from the first container to the subsequent container takes place by means of pressure, so that the melt dispersion is pumped/pressed from the first container into the subsequent container. Pumping out the melt in this way offers the advantage that a largely complete, rapid transfer of the melt from one container to the next is ensured, so that as little residual material as possible, which remains as a residue in the respective outlet container, is lost.
- the transfer of the melt dispersion from the first to the subsequent container or from the subsequent container for reshaping can also take place directly by means of suitable mixing units.
- the carrier material can be melted in an additional container upstream of the first container.
- the carrier material is basically melted by heating it to a temperature that is no more than 20° C. above the melting point of the carrier material. This also applies if the carrier material is melted in the first container already described. The melting can be carried out using all customary methods and devices known to those skilled in the art.
- the carrier material melted in this way can then, in a step i) of the method preceding method step a), as described herein, be transferred to the first container in order to produce the melt dispersion according to step i).
- the first container additionally comprises at least one adjustable opening which allows the introduction of a carrier material so melted.
- the method described herein is accordingly characterized in that the carrier material is melted in a step a) preceding step i).
- the individual flows can optionally be controlled by means of flow rate measurement of the individual metering streams, i.e. the melt, the fragrance stream and, if necessary, other streams will. This can also be used, for example, to set the proportions of the individual components.
- the method according to the invention is preferably characterized in that the melt dispersion produced in step i) is transferred from the first container directly into the subsequent container.
- the manufacturing method according to the invention is a sequential process sequence.
- a process sequence as described herein can be continuous or as Batch processes take place, with a continuous process being preferred.
- the continuous process management makes it possible to change the amount or chemical nature of the aesthetic agent used during operation, for example to stop the supply of fragrance in step ii) and to switch production to an alternative process product.
- Due to the late dosing of the esthetic in step ii) its residues only have to be flushed out of one part of the production system (the part of the production system downstream of the dosing point for the esthetic) in the event of such a change by the subsequent melt dispersion.
- the corresponding forerun which contains an undesired mixture of several esthetics or an incorrect concentration of the desired esthetic, can be discarded or can be recycled as waste material (in step i) or ii).
- an advantage of the method as described here is that production changes are made possible without great effort. Due to the sequential process flow, the components to be added in the individual process steps, i.e. carrier material, solid, dye, fragrance and any other ingredients, can be exchanged for alternatives as far as possible separately from one another without the entire manufacturing process having to come to a standstill. In addition, the accumulation of large quantities of unsuitable product quantities can be avoided in this way. If, for example, a fragrance and/or colorant is to be changed, the supply of the fragrance and/or colorant is first stopped and the melt dispersion produced in step i) continues to be transferred from the first container to the second container and from there forwarded for forming.
- the system is, so to speak, “rinsed” with the fragrance-free and/or dye-free melt and residual fragrance and/or dye is removed.
- the waste obtained in this way can later be fed back into the process when the same fragrance and/or colorant is used again.
- Another colorant and/or fragrance can then be added, with the forerun being discarded or returned to the process as waste material. Since melt is produced continuously, the fragrance and/or colorant is changed during the ongoing process, so to speak, and the amount of waste is comparatively small.
- the method described herein is characterized in that waste material obtained after step ii) is returned to step i) or ii), preferably to step i).
- the melt dispersion produced in step i) is mixed with at least one aesthetic agent outside the first container.
- Step ii) is preferably carried out either (1) in a container downstream of the first container or (2) directly in the outflow stream emerging from the first container.
- the melt dispersion is transferred to a subsequent container and in this container with at least mixed with an aesthetic; or (2) the at least one aesthetic is continuously mixed into the effluent stream of the first container
- the admixing of the esthetic into the outflow stream of the first container can be implemented, for example, by providing the pipeline through which the melt dispersion is discharged from the first container with a supply line for the esthetic.
- the first and subsequent containers are in communication with each other.
- the melt dispersion produced in the first container is transferred to the subsequent container via this connection.
- Downstream or “subsequent” as used in this context means that the container in question is downstream of the first container, i.e. the volume flow from the first container reaches this subsequent container at a later point in time in the process.
- the volume flow emerging from the first container has previously passed through other, intermediate containers.
- the container comprises at least one adjustable opening through which the melt dispersion produced in step i) can be introduced into the container, at least one further adjustable opening through which the esthetic (and any other components) can be introduced into the container, and in addition, at least one adjustable opening through which the melt dispersion produced in step ii) can be discharged from the container.
- This container can also be a suitable mixing unit, such as a static mixer, for example.
- the mixing can also take place by continuously admixing the at least one aesthetic agent into the outflow stream emerging from the first container, i.e. without the need for a separate container.
- the opening through which the at least one aesthetic agent is introduced into the melt dispersion can preferably be regulated.
- Aesthetics designates an active ingredient or auxiliary which is temperature-sensitive at the temperature used to produce the melt dispersion in step i), ie chemically or physically disintegrates at this temperature.
- Aesthetics refers in particular to an active ingredient or auxiliary whose use in the melting bodies can be perceived by the consumer's senses.
- the group of aesthetics includes the fragrances and dyes.
- the fragrance is preferably used in liquid form, for example as a perfume oil, a solution in a suitable solvent or as a suspension of perfume capsules in a typically aqueous solvent.
- "Liquid” as used in this context means liquid under the conditions of use, preferably liquid at 20°C.
- the at least one fragrance is a substantially "dry", i.e. substantially anhydrous, component.
- the method described herein is characterized in that the at least one fragrance is used in the form of fragrance capsules and/or perfume oils.
- the dye is preferably also used in liquid form, for example in the form of an aqueous solution or slurry.
- suitable dye preparations can also contain organic solvents, in particular polyols.
- a third step iii) the melt dispersion obtained in step ii) is reshaped in order to obtain solid melt bodies. For example, via the above-mentioned opening, which enables the melt dispersion produced in step ii) to be discharged from the downstream container, the melt produced is fed to the forming process.
- the melt obtained after step ii) can be shaped using customary shaping methods. Suitable shaping methods are known to those skilled in the art and involve cooling the melt to a temperature below the melting temperature of the carrier material, so that the melt solidifies and thereby/then acquires its final shape. Examples include pastillation, dripping, melt extrusion, prilling, and others. According to preferred embodiments, the forming in step iii) takes place by means of a cooling belt.
- the melt dispersion produced in step i) is discharged from the first container by means of a pipeline and fed to the droplet former. It is furthermore preferred that the at least one aesthetic agent is continuously introduced into the outflow stream of the first container by means of a further pipeline from a corresponding storage container.
- a liquid preparation of the aesthetic agent for example in the form of a solution, is particularly suitable for this.
- the temperature of the esthetic or the liquid preparation of the esthetic before it is introduced into the outflow stream of the first container is preferably at least 10°C, preferably at least 20°C and in particular at least 30°C below the temperature of the melt dispersion forming the outflow stream.
- the mixing preferably takes place by means of a static mixer, which is located in the pipeline in the direction of flow of the melt dispersion behind the entry point of the esthetic and before the entry point of the mixture into the droplet former.
- the length of the static mixer fitted in the pipeline in the direction of flow of the melt dispersion is preferably at least 10 times, preferably at least 20 times and in particular at least 50 times the diameter of the pipeline.
- the distance between the end of the static mixer and the point of entry of the pipeline into the drop former is less than 500 times, preferably less than 200 times and in particular less than 100 times the diameter of the pipeline.

Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Schmelzkörpern, umfassend das Herstellen einer Schmelzdispersion umfassend mindestens ein wasserlösliches oder wasserdispergierbares Trägermaterial und mindestens einen Feststoff in einem ersten Behälter; Vermischen der so erhaltenen Schmelzdispersion mit mindestens einem Ästhetikum in einem nachfolgenden Behälter und Umformen der so erhaltenen Schmelzdispersion, um feste Pastillen zu erhalten. Offenbart werden weiterhin auf die nach diesem Verfahren hergestellten Schmelzkörper, auf ein Wasch- oder Reinigungsmittel, das diese enthält, auf die Verwendung eines solchen Wasch- oder Reinigungsmittels zum Reinigen von Textilien oder harten Oberflächen sowie entsprechende Verfahren zum Reinigen von Textilien oder harten Oberflächen unter Verwendung eines solchen Wasch- oder Reinigungsmittels.The present invention relates to a method for producing melted bodies, comprising the production of a melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid in a first container; Mixing the melt dispersion thus obtained with at least one aesthetic agent in a subsequent container and shaping the melt dispersion thus obtained to obtain solid lozenges. Also disclosed are the melting bodies produced by this method, a detergent or cleaning agent containing them, the use of such a detergent or cleaning agent for cleaning textiles or hard surfaces and corresponding methods for cleaning textiles or hard surfaces using such a washing or cleaning agent.
Bei der Anwendung von Wasch- und Reinigungsmitteln verfolgt der Verbraucher nicht nur das Ziel, die zu behandelnden Objekte zu waschen, zu reinigen oder zu pflegen, sondern er wünscht sich auch, dass die behandelten Objekte, wie z.B. Textilien, nach der Behandlung, beispielsweise nach der Wäsche, angenehm riechen. Insbesondere aus diesem Grunde enthalten die meisten kommerziell verfügbaren Wasch- und Reinigungsmittel Duftstoffe.When using detergents and cleaning agents, the consumer not only pursues the goal of washing, cleaning or caring for the objects to be treated, but he also wishes that the treated objects, such as textiles, after the treatment, for example after the laundry, smell pleasant. For this reason in particular, most commercially available detergents and cleaning agents contain fragrances.
Die meisten der Duftstoffe sind jedoch leichtflüchtig. Aus diesem Grund verbleibt beim Einsatz herkömmlicher Wasch- oder Reinigungsmittel nach der Anwendung, insbesondere nach dem Waschen, nur ein geringer Anteil des eingesetzten Duftstoffes auf dem behandelten Objekt.However, most of the fragrances are volatile. For this reason, when using conventional detergents or cleaning agents, only a small proportion of the fragrance used remains on the treated object after use, especially after washing.
Dadurch geht oft nur ein schwacher Duft von dem behandelten Objekt, wie insbesondere der Wäsche, aus, welcher dann bereits nach kurzer Zeit immer schwächer wird. So verschwindet das angenehme Frischegefühl des behandelten Objekts schon nach kurzer Zeit.As a result, the treated object, such as the laundry in particular, often only gives off a faint scent, which then becomes weaker and weaker after a short time. The pleasant feeling of freshness of the treated object disappears after a short time.
Oftmals werden Duftstoffe in Form von Duftstoffpastillen entweder als integraler Bestandteil eines Wasch- oder Reinigungsmittels verwendet, oder aber direkt zu Beginn eines Waschgangs in separater Form in die Waschtrommel dosiert. Auf diese Weise kann der Verbraucher durch individuelle Dosierung die Beduftung der zu waschenden Wäsche kontrollieren.Fragrances in the form of fragrance pastilles are often used either as an integral part of a washing or cleaning agent, or are metered into the washing drum in a separate form directly at the start of a wash cycle. In this way, the consumer can control the scent of the laundry to be washed through individual dosing.
Derartige Duftpastillen werden üblicherweise aus Schmelzdispersionen hergestellt, deren Hauptbestandteil ein wasserlösliches oder wasserdispergierbares Trägermaterial mit einer geeigneten Schmelztemperatur ist. Neben den ebenfalls enthaltenden Duftkomponenten und gegebenenfalls sonstigen Hilfsstoffen, wie waschaktiven Substanzen, können solchen Schmelzdispersionen auch Feststoffe zugesetzt werden, um beispielsweise die Viskosität der zu verarbeitenden Dispersion zu beeinflussen. Die Produktion der Pastillen erfordert die ununterbrochene Bereitstellung einer solchen Schmelzdispersion.Such scent pastilles are usually made from melt dispersions, the main component of which is a water-soluble or water-dispersible carrier material with a suitable melting point. In addition to the fragrance components and optionally other auxiliaries, such as washing-active substances, solids can also be added to such melt dispersions in order, for example, to influence the viscosity of the dispersion to be processed. The production of the pastilles requires the continuous supply of such a melt dispersion.
Die Bereitstellung der Schmelzdispersion erfolgt naturgemäß bei Temperaturen oberhalb Raumtemperatur, wobei die absolute Temperatur der Schmelzdispersion durch die chemischeThe melt dispersion is naturally provided at temperatures above room temperature, the absolute temperature of the melt dispersion being determined by the chemical
Natur des Trägermaterials ebenso bestimmt wird wie durch den weiteren Prozessverlauf, beispielsweise den im Prozessverlauf vorgesehenen oder eben nicht vorgesehenen Einsatz zusätzlicher Heiz- oder Kühlelemente.The nature of the carrier material is determined as well as by the further course of the process, for example the use of additional heating or cooling elements provided or not provided in the course of the process.
Die erhöhte Temperatur der Schmelzdispersion kann sich auf die chemische Integrität der eingesetzten Wirk- und Hilfsstoffe und/oder auf die physikalische Integrität des eingesetzten Stoffsystems, beispielsweise dessen Lagerstabilität auswirken.The elevated temperature of the melt dispersion can affect the chemical integrity of the active substances and auxiliaries used and/or the physical integrity of the substance system used, for example its storage stability.
Im Hinblick auf die chemische Integrität der eingesetzten Wirk- und Hilfsstoffe sind insbesondere solche Instabilitäten zu vermeiden, welche durch den Verbraucher in einfacher Weise sensorisch wahrgenommen werden können. Hierzu zählen vornehmlich der Duft und die Farbwirkung der Schmelzkörper. Aus diesem Grund sind längere Verweilzeiten der temperaturempfindlichen Duft- und Farbkomponente bei höheren Temperaturen, d.h. Temperaturen entsprechend der Schmelztemperatur des Trägermaterials, wenn möglich zu vermeiden.With regard to the chemical integrity of the active ingredients and auxiliaries used, in particular those instabilities which can easily be perceived by the consumer's senses should be avoided. These primarily include the scent and the color effect of the melting body. For this reason, longer dwell times of the temperature-sensitive fragrance and color components at higher temperatures, i.e. temperatures corresponding to the melting temperature of the carrier material, should be avoided if possible.
Zusätzlich sind insbesondere solche Prozessabläufe wünschenswert, die eine unkomplizierte, mit wenig Aufwand verbundene Produktumstellung (anderes Parfüm, andere Farbe) ermöglichen. Weiterhin sollten allgemein größere Mengen nicht verkaufsgeeigneter, nicht spezifikationsgerechter Ware (Verschnittmaterial) bei Produktumstellungen vermieden werden.In addition, such process sequences are particularly desirable that enable an uncomplicated product changeover (different perfume, different color) with little effort. Furthermore, large quantities of goods that are not suitable for sale and do not meet the specifications (waste material) should generally be avoided when changing products.
Im Stand der Technik sind Herstellungsverfahren üblich, in denen zunächst eine Schmelze bestehend aus dem Trägermaterial sowie ggf. Feststoffen und weiteren Bestandteilen erzeugt wird und die so erhaltene Schmelze direkt mit der Duftkomponente sowie ggf. noch weiteren Bestandteilen, wie Farbstoffen, vermischt wird. Die fertige Schmelzdispersion wird anschließend zu Pastillen geformt. Bei einem derartigen Herstellungsverfahren, welches beispielsweise in dem europäischen Patent
Es besteht folglich weiterhin Bedarf an einem verbesserten Herstellungsverfahren für Schmelzkörperpastillen, insbesondere Duftpastillen, welches die erwähnten Nachteile minimiert oder sogar eliminiert.Consequently, there is still a need for an improved manufacturing process for fusible pastilles, in particular scented pastilles, which minimizes or even eliminates the disadvantages mentioned.
Diese Aufgabe wurde erfindungsgemäß durch ein Verfahren gelöst, welches mindestens drei separate, aufeinander folgende Verfahrensschritte umfasst, sodass ein ununterbrochener Produktionsprozess bereitgestellt wird.According to the invention, this object was achieved by a method which comprises at least three separate, successive method steps, so that an uninterrupted production process is provided.

- iii) Reshaping of the mixture obtained in step ii) in order to obtain solid melt bodies.

Diese und weitere Aspekte, Merkmale und Vorteile der Erfindung werden für den Fachmann aus dem Studium der folgenden detaillierten Beschreibung und Ansprüche ersichtlich. Dabei kann jedes Merkmal aus einem Aspekt der Erfindung in jedem anderen Aspekt der Erfindung eingesetzt werden. Ferner ist es selbstverständlich, dass die hierin enthaltenen Beispiele die Erfindung beschreiben und veranschaulichen sollen, diese aber nicht einschränken und insbesondere die Erfindung nicht auf diese Beispiele beschränkt ist.These and other aspects, features and advantages of the invention will become apparent to those skilled in the art from a study of the following detailed description and claims. Each feature from one aspect of the invention can be used in any other aspect of the invention. Furthermore, it should be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular the invention is not limited to these examples.
"Schmelzkörper", wie hierin verwendet, bezeichnet nicht poröse, schmelzbare, wasserlösliche oder wasserdispergierbare bei Standardbedingungen (20°C, 1013 mbar) als Feststoffe vorliegende Körper, die durch Erstarren und Umformung der hierin beschriebenen Schmelzen erhältlich sind.“Melt bodies” as used herein, designates bodies that are non-porous, meltable, water-soluble or water-dispersible under standard conditions (20° C., 1013 mbar) as solids and can be obtained by solidification and reshaping of the melts described herein.

Beispielsweise können die Schmelzkörper eine Gummibärchen-artige, figürliche Ausgestaltung haben. Aufgrund ihrer Konfektionierungseigenschaften und ihres Leistungsprofils sind hemisphärische Schmelzkörper besonders bevorzugt.Shapes, such as essentially spherical, figurative, scaly, cuboid, cylindrical, conical, spherical cap or lens, hemispherical, disc or needle-shaped melted bodies. For example, the melted bodies can have a figured configuration resembling a gummy bear. Due to their assembly properties and their performance profile, hemispherical melting bodies are particularly preferred.
Bevorzugte Schmelzkörper weisen in beliebiger Raumrichtung einen maximalen Durchmesser zwischen 4 und 15 mm, vorzugsweise zwischen 5 und 10 mm auf. Besonders bevorzugte Schmelzkörper sind durch einen maximalen Durchmesser von 2 bis 8 mm, besonders bevorzugt von 4 bis 6 mm gekennzeichnet. Derartige Schmelzkörper sind einerseits besonders gut wasserlöslich und weisen andererseits eine für den Verbraucher optisch ansprechende Größe auf.Preferred melted bodies have a maximum diameter of between 4 and 15 mm, preferably between 5 and 10 mm, in any spatial direction. Particularly preferred melted bodies are characterized by a maximum diameter of 2 to 8 mm, particularly preferably 4 to 6 mm. On the one hand, such melted bodies are particularly readily water-soluble and, on the other hand, have a size that is visually appealing to the consumer.
100% hemispährische (halbkugelförmige) Partikel sind durch Verhältnis von Höhe zu Durchmesser von 0,5 gekennzeichnet. Erfindungsgemäß werden auch solche Schmelzkörper als hemisphärisch bezeichnet, die ein Verhältnis von Höhe zu Durchmesser von 0,25 bis 0,49 aufweisen. Besonders bevorzugt sind Schmelzkörper mit einem Verhältnis von Höhe zu Durchmesser von 0,35 bis 0,45.100% hemispherical (hemispherical) particles are characterized by a height to diameter ratio of 0.5. According to the invention, those melted bodies which have a height-to-diameter ratio of 0.25 to 0.49 are also referred to as hemispherical. Particularly preferred are melted bodies with a height-to-diameter ratio of 0.35 to 0.45.
Üblicherweise liegt das Gewicht der einzelnen Schmelzkörper zwischen 2 bis 150 mg, vorzugsweise zwischen 5 bis 10 mg.The weight of the individual melted bodies is usually between 2 and 150 mg, preferably between 5 and 10 mg.
"Wasserlöslich", wie hierin verwendet, bedeutet eine Löslichkeit in Wasser bei 20°C von mindestens 1 g/L, vorzugsweise mindestens 10 g/L, noch bevorzugter mindestens 50 g/L."Water-soluble" as used herein means a solubility in water at 20°C of at least 1 g/L, preferably at least 10 g/L, more preferably at least 50 g/L.
"Wasserdispergierbar", wie hierin verwendet, bedeutet, dass sich das Trägermaterial mit bekannten Verfahren in Wasser bei einer Temperatur von 20°C dispergieren lässt."Water-dispersible" as used herein means that the carrier material can be dispersed in water at a temperature of 20°C using known methods.
Alle Prozentangaben sind, sofern nicht anders angegeben, Gewichts-%. Numerische Bereiche, die in dem Format "von x bis y" angegeben sind, schließen die genannten Werte ein. Wenn mehrere bevorzugte numerische Bereiche in diesem Format angegeben sind, ist es selbstverständlich, dass alle Bereiche, die durch die Kombination der verschiedenen Endpunkte entstehen, ebenfalls erfasst werden.All percentages are % by weight unless otherwise indicated. Numerical ranges given in the format "from x to y" include the stated values. Where multiple preferred numeric ranges are given in this format, it is understood that any ranges resulting from the combination of the different endpoints are also included.
"Mindestens ein", wie hierin verwendet, bezieht sich auf 1 oder mehr, beispielsweise 1, 2, 3, 4, 5, 6, 7, 8, 9 oder mehr. Insbesondere bezieht sich diese Angabe auf die Art des Mittels/der Verbindung und nicht die absolute Zahl der Moleküle. "Mindestens ein Duftstoff", bedeutet daher, dass mindestens eine Art von Duftstoff erfasst wird, aber auch 2 oder mehr verschiedene Arten von Duftstoffen enthalten sein können."At least one" as used herein refers to 1 or more, for example 1, 2, 3, 4, 5, 6, 7, 8, 9 or more.

"At least one fragrance" therefore means that at least one type of fragrance is detected, but it can also contain 2 or more different types of fragrance.
Die vorliegende Erfindung richtet sich auf ein Herstellungsverfahren für Schmelzkörper, wie zum Beispiel Duftpastillen, wobei eine Schmelzdispersion in einer ununterbrochenen Prozessabfolge hergestellt und in einem letzten Schritt umgeformt wird. Das wie hierin beschriebene Verfahren zeichnet sich dadurch aus, dass Produktumstellungen, d.h. veränderte Zusammensetzung der Schmelzdispersion, beispielsweise durch Verwendung einer anderen Duft- und/oder Farbkomponente, ohne großen Aufwand möglich sind, wobei darüber hinaus das Anfallen verkaufsunfähiger Produktmengen weitestgehend vermieden werden kann. Ein weiterer Vorteil des wie hierin beschriebenen Verfahrens besteht darin, dass das in die herzustellende Schmelzdispersion eingearbeitete, temperaturempfindliche Ästhetikum eine, im Vergleich zu im Stand der Technik bekannten Herstellungsverfahren, kurze Verweilzeit bei erhöhten Temperaturen (entsprechend der Schmelztemperatur des jeweiligen Trägermaterials) hat, wodurch nach dem wie hierin beschriebenen Verfahren hergestellte Pastillen eine verbesserte Farbwirkung und/oder eine verbesserte Beduftung bei ihrer Verwendung zeigen.The present invention relates to a manufacturing method for melted bodies, such as scented pastilles, in which a melted dispersion is produced in an uninterrupted process sequence and shaped in a final step. The method as described here is characterized in that product changes, i.e. changing the composition of the melt dispersion, for example by using a different fragrance and/or color component, are possible without great effort, and it is also possible to largely avoid the accumulation of salable product quantities. Another advantage of the method as described here is that the temperature-sensitive aesthetics incorporated into the melt dispersion to be produced has a short residence time at elevated temperatures (corresponding to the melting temperature of the respective carrier material) compared to production methods known in the prior art, which lozenges produced by the process as described herein show an improved color effect and/or an improved fragrancing upon their use.
Ein erster Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Herstellung von Schmelzkörpern. Gemäß der vorliegenden Erfindung umfasst das Verfahren die nachfolgend beschriebenen Schritte:
In einem ersten Schritt i) wird, in einem ersten Behälter, eine parfümfreie Schmelzdispersion umfassend mindestens ein wasserlösliches oder wasserdispergierbares Trägermaterial und mindestens einen Feststoff hergestellt. Das eingesetzte wasserlösliche oder wasserdispergierbare geschmolzene Trägermaterial weist eine Schmelztemperatur von >30°C, vorzugsweise >40°C und insbesondere >50°C auf.A first object of the present invention is therefore a method for the production of melted bodies. According to the present invention, the method comprises the steps described below:
In a first step i), a perfume-free melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid is produced in a first container. The water-soluble or water-dispersible molten carrier material used has a melting point of >30°C, preferably >40°C and in particular >50°C.
Behälter, die für diesen Zweck geeignet sind, sind dem Fachmann generell geläufig. Voraussetzung für die Anwendbarkeit in einem wie hierin beschriebenen Verfahren ist allerdings, dass der Behälter ein gründliches Vermischen der Komponenten der in Schritt i) herzustellenden Schmelzdispersion ermöglicht und des Weiteren mindestens eine regulierbare Öffnung umfasst, über die die Komponenten der in Schritt i) herzustellenden Schmelzdispersion in den Behälter eingebracht werden können, sowie zusätzlich mindestens eine weitere regulierbare Öffnung, über die die in Schritt i) hergestellte Schmelzdispersion aus dem Behälter entlassen werden kann. Über diese Öffnungen können Ein- und/oder Auslassstrom mengengesteuert werden. Bei dem ersten Behälter kann es sich beispielsweise um ein Mischaggregat handeln. Die Bestandteile der Schmelze werden dabei auf eine Temperatur über dem Schmelzpunkt des Trägermaterials erhitzt, vorzugsweise auf eine Temperatur oberhalb 40°C, bevorzugter oberhalb 50°C. Alternativ oder zusätzlich kann das Trägermaterial bereits in geschmolzener Form zugeführt und in dem ersten Behälter mit dem mindestens einen Feststoff vermischt werden.Containers suitable for this purpose are generally known to those skilled in the art. However, a prerequisite for the applicability in a method as described here is that the container enables thorough mixing of the components of the melt dispersion to be produced in step i) and also comprises at least one adjustable opening through which the components of the melt dispersion to be produced in step i) in can be introduced into the container, and additionally at least one further adjustable opening through which the melt dispersion produced in step i) can be discharged from the container. Inlet and/or outlet flow can be volume-controlled via these openings. The first container can be a mixing unit, for example. The components of the melt are heated to a temperature above the melting point of the carrier material, preferably to a temperature above 40°C, more preferably above 50°C. Alternatively or additionally, the carrier material can already be supplied in molten form and mixed with the at least one solid in the first container.
Gemäß einigen Ausführungsformen erfolgt die Überführung der Schmelzdispersion aus dem ersten Behälter in den nachfolgenden Behälter mittels Druck, sodass die Schmelzdispersion aus dem ersten Behälter in den nachfolgenden Behälter gepumpt/gepresst wird. Ein derartiges Herauspumpen der Schmelze bietet den Vorteil, dass eine weitestgehend vollständige, zügige Überführung der Schmelze von einem Behälter in den nächsten gewährleistet wird, sodass möglichst wenig Restmaterial, welches als Rückstand in dem jeweiligen Austrittsbehälter verbleibt, verlorengeht. Gleiches gilt für den Auslass der in Schritt ii) hergestellten Schmelzdispersion. Das Überführen der Schmelzdispersion aus dem ersten in den nachfolgenden Behälter bzw. aus dem nachfolgenden Behälter zur Umformung kann auch direkt mittels geeigneter Mischaggregate erfolgen.According to some embodiments, the transfer of the melt dispersion from the first container to the subsequent container takes place by means of pressure, so that the melt dispersion is pumped/pressed from the first container into the subsequent container. Pumping out the melt in this way offers the advantage that a largely complete, rapid transfer of the melt from one container to the next is ensured, so that as little residual material as possible, which remains as a residue in the respective outlet container, is lost. The same applies to the outlet of the melt dispersion produced in step ii). The transfer of the melt dispersion from the first to the subsequent container or from the subsequent container for reshaping can also take place directly by means of suitable mixing units.
Um auch einen prozessökonomischen Austausch des Trägermaterials zu gewährleisten, kann das Aufschmelzen des Trägermaterials in einem zusätzlichen, dem ersten Behälter vorgeschalteten Behälter erfolgen. In verschiedenen Ausführungsformen erfolgt das Schmelzen des Trägermaterials grundsätzlich durch Erwärmen desselben auf eine Temperatur, die nicht mehr als 20 °C über dem Schmelzpunkt des Trägermaterials liegt. Dies gilt auch, wenn das Aufschmelzen des Trägermaterials in dem bereits beschriebenen ersten Behälter erfolgt. Das Schmelzen kann mit allen üblichen und den Fachmann bekannten Verfahren und Vorrichtungen erfolgen. Gemäß einigen Ausführungsformen kann das so aufgeschmolzene Trägermaterial dann, in einem Schritt i) des wie hierin beschriebenen Verfahrens vorgeschalteten Verfahrensschritt a), in den ersten Behälter überführt werden, um die Schmelzdispersion gemäß Schritt i) herzustellen. Es ist entsprechend wünschenswert, dass der erste Behälter zusätzlich zumindest eine regulierbare Öffnung umfasst, welche die Einleitung eines so aufgeschmolzenen Trägermaterials ermöglicht. Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren dementsprechend dadurch aus, dass das Trägermaterial in einem Schritt i) vorgeschalteten Schritt a) aufgeschmolzen wird.In order to also ensure a process-economical replacement of the carrier material, the carrier material can be melted in an additional container upstream of the first container. In various embodiments, the carrier material is basically melted by heating it to a temperature that is no more than 20° C. above the melting point of the carrier material. This also applies if the carrier material is melted in the first container already described. The melting can be carried out using all customary methods and devices known to those skilled in the art. According to some embodiments, the carrier material melted in this way can then, in a step i) of the method preceding method step a), as described herein, be transferred to the first container in order to produce the melt dispersion according to step i). Accordingly, it is desirable that the first container additionally comprises at least one adjustable opening which allows the introduction of a carrier material so melted. According to some embodiments, the method described herein is accordingly characterized in that the carrier material is melted in a step a) preceding step i).
Bei der Herstellung sowohl der Schmelze aus Schritt i) sowie der Schmelze aus Schritt ii) können die einzelnen Durchflüsse (sämtliche Materialein/ausleitungen, wie hierin beschrieben) optional mittels Durchflussmengenmessung der einzelnen Dosierströme, d.h. der Schmelze, des Duftstoffstroms und ggf. weiterer Ströme gesteuert werden. Hierüber lassen sich beispielsweise auch die Mengenverhältnisse der einzelnen Bestandteile einstellen.When producing both the melt from step i) and the melt from step ii), the individual flows (all material inlets/outlets, as described herein) can optionally be controlled by means of flow rate measurement of the individual metering streams, i.e. the melt, the fragrance stream and, if necessary, other streams will. This can also be used, for example, to set the proportions of the individual components.
Das erfindungsgemäße Verfahren zeichnet sich vorzugsweise dadurch aus, dass die in Schritt i) hergestellte Schmelzdispersion aus dem ersten Behälter direkt in den nachfolgenden Behälter überführt wird.The method according to the invention is preferably characterized in that the melt dispersion produced in step i) is transferred from the first container directly into the subsequent container.
Bei dem erfindungsgemäßen Herstellungsverfahren handelt es sich um eine sequentielle Prozessabfolge. Eine wie hierin beschriebene Prozessabfolge kann kontinuierlich oder auch als Batch-Verfahren erfolgen, wobei ein kontinuierlicher Prozess bevorzugt ist. Die kontinuierliche Prozessführung ermöglicht es, im laufenden Betrieb die Menge oder chemische Natur des eingesetzten Ästhetikums zu ändern, beispielsweise die Zuführung von Duftstoff in Schritt ii) zu stoppen, und die Produktion auf ein alternatives Verfahrensprodukt umzustellen. Aufgrund der zeitlich späten Eindosierung des Ästhetikums in Schritt ii), müssen dessen Restemengen bei einer solchen Änderung durch die nachfließende Schmelzdispersion nur aus einem Teil der Produktionsanlage (dem der Dosierstelle für das Ästhetikum nachfolgenden Teil der Produktionsanlage) ausgespült werden. Der entsprechende Vorlauf, welcher eine unerwünschte Mischung mehrerer Ästhetika oder eine falsche Konzentration des erwünschten Ästhetikums enthält, kann verworfen oder als Verschnittmaterial zurückgeführt werden kann (in Schritt i) oder ii).The manufacturing method according to the invention is a sequential process sequence. A process sequence as described herein can be continuous or as Batch processes take place, with a continuous process being preferred. The continuous process management makes it possible to change the amount or chemical nature of the aesthetic agent used during operation, for example to stop the supply of fragrance in step ii) and to switch production to an alternative process product. Due to the late dosing of the esthetic in step ii), its residues only have to be flushed out of one part of the production system (the part of the production system downstream of the dosing point for the esthetic) in the event of such a change by the subsequent melt dispersion. The corresponding forerun, which contains an undesired mixture of several esthetics or an incorrect concentration of the desired esthetic, can be discarded or can be recycled as waste material (in step i) or ii).
Wie bereits erwähnt besteht ein Vorteil des wie hierin beschriebenen Verfahrens darin, dass Produktionsumstellungen ohne großen Aufwand ermöglicht werden. Durch den sequentiellen Prozessablauf können die in den einzelnen Verfahrensschritten zuzuführenden Komponenten, d.h. Trägermaterial, Feststoff, Farbstoff, Duftstoff sowie ggf. weitere Inhaltsstoffe, weitestgehend separat voneinander gegen Alternativen ausgetauscht werden, ohne dass der gesamte Herstellungsprozess zum Erliegen kommen muss. Darüber hinaus kann auf diese Weise das Anfallen großer Mengen an verkaufsungeeigneten Produktmengen vermieden werden. Soll beispielsweise ein Duft- und/oder Farbstoffwechsel erfolgen, wird zunächst die Zuführung des Duft- und/oder Farbstoffs gestoppt und die in Schritt i) hergestellte Schmelzdispersion weiterhin aus dem ersten Behälter in den zweiten Behälter überführt und aus diesem zur Umformung weitergeleitet. Dadurch wird das System sozusagen mit der duft- und/oder farbstofffreien Schmelze "gespült" und Duft- und/oder Farbstoffreste entfernt. Der so erhaltene Verschnitt kann später bei einem erneuten Einsatz desselben Duft- und/oder Farbstoffs in den Prozess zurückgeführt werden. Anschließend kann ein anderer Farb- und/oder Duftstoff zugeführt werden, wobei der Vorlauf wiederum verworfen oder als Verschnittmaterial in den Prozess zurückgeführt werden kann. Da ununterbrochen Schmelze erzeugt wird, erfolgt der Wechsel des Duft- und/oder Farbstoffs sozusagen im laufenden Prozess und die Verschnittmengen sind vergleichsweise gering.As already mentioned, an advantage of the method as described here is that production changes are made possible without great effort. Due to the sequential process flow, the components to be added in the individual process steps, i.e. carrier material, solid, dye, fragrance and any other ingredients, can be exchanged for alternatives as far as possible separately from one another without the entire manufacturing process having to come to a standstill. In addition, the accumulation of large quantities of unsuitable product quantities can be avoided in this way. If, for example, a fragrance and/or colorant is to be changed, the supply of the fragrance and/or colorant is first stopped and the melt dispersion produced in step i) continues to be transferred from the first container to the second container and from there forwarded for forming. As a result, the system is, so to speak, “rinsed” with the fragrance-free and/or dye-free melt and residual fragrance and/or dye is removed. The waste obtained in this way can later be fed back into the process when the same fragrance and/or colorant is used again. Another colorant and/or fragrance can then be added, with the forerun being discarded or returned to the process as waste material. Since melt is produced continuously, the fragrance and/or colorant is changed during the ongoing process, so to speak, and the amount of waste is comparatively small.
Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren dadurch aus, dass Verschnittmaterial, welches nach Schritt ii) erhalten wird in Schritt i) oder ii), vorzugsweise in Schritt i) zurückgeführt wird.According to some embodiments, the method described herein is characterized in that waste material obtained after step ii) is returned to step i) or ii), preferably to step i).
In einem zweiten Schritt ii) wird die in Schritt i) hergestellte Schmelzdispersion mit mindestens einem Ästhetikum außerhalb des ersten Behälters vermischt. Dabei wird Schritt ii) vorzugsweise entweder (1) in einem dem ersten Behälter nachgeordneten Behälter oder (2) direkt in dem aus dem ersten Behälter austretenden Auslaufstrom durchgeführt. Mit anderen Worten wird (1) die Schmelzdispersion in einen nachfolgenden Behälter überführt wird und in diesem mit mindestens einem Ästhetikum vermischt oder (2) das mindestens eine Ästhetikum kontinuierlich in den Auslaufstrom des ersten Behälters zugemischt wirdIn a second step ii), the melt dispersion produced in step i) is mixed with at least one aesthetic agent outside the first container. Step ii) is preferably carried out either (1) in a container downstream of the first container or (2) directly in the outflow stream emerging from the first container. In other words, (1) the melt dispersion is transferred to a subsequent container and in this container with at least mixed with an aesthetic; or (2) the at least one aesthetic is continuously mixed into the effluent stream of the first container
Das Zumischen des Ästhetikums in den Auslaufstrom des ersten Behälters kann beispielsweise realisiert werden, indem die Rohrleitung, durch welche die Schmelzdispersion aus dem ersten Behälter ausgeleitet wird, mit einer Zuleitung für das Ästhetikum versehen wird.The admixing of the esthetic into the outflow stream of the first container can be implemented, for example, by providing the pipeline through which the melt dispersion is discharged from the first container with a supply line for the esthetic.
Der erste und der nachfolgende Behälter stehen, gemäß der vorliegenden Erfindung, in Verbindung miteinander. Über diese Verbindung wird, gemäß der vorliegenden Erfindung, die in dem ersten Behälter hergestellte Schmelzdispersion in den nachfolgenden Behälter überführt. "Nachgeordnet" oder "nachfolgend", wie in diesem Kontext verwendet, bedeutet, dass der betreffende Behälter von dem ersten Behälter aus gesehen diesem nachgeschaltet ist, d.h. der Volumenstrom aus dem ersten Behälter zu einem späteren Verfahrenszeitpunkt in diesen nachfolgenden Behälter gelangt. Es ist aber durchaus möglich, dass der aus dem ersten Behälter austretende Volumenstrom vorher noch andere, zwischengeschaltete Behälter, durchläuft.According to the present invention, the first and subsequent containers are in communication with each other. According to the present invention, the melt dispersion produced in the first container is transferred to the subsequent container via this connection. "Downstream" or "subsequent" as used in this context means that the container in question is downstream of the first container, i.e. the volume flow from the first container reaches this subsequent container at a later point in time in the process. However, it is quite possible that the volume flow emerging from the first container has previously passed through other, intermediate containers.
Auch für den nachfolgenden Behälter gilt, dass ein gründliches Vermischen der in den Behälter eingeleiteten Komponenten gewährleistet werden muss. Weitern umfasst der Behälter mindestens eine regulierbare Öffnung, über welche die in Schritt i) hergestellte Schmelzdispersion in den Behälter eingeleitet werden kann, mindestens eine weitere regulierbare Öffnung, über welche das Ästhetikum (sowie ggf. weitere Komponenten) in den Behälter einleitet werden kann, sowie darüber hinaus zusätzlich mindestens eine regulierbare Öffnung, über welche die in Schritt ii) hergestellte Schmelzdispersion aus dem Behälter entlassen werden kann. Auch dieser Behälter kann beispielsweise ein geeignetes Mischaggregat, wie z.B. ein statischer Mischer, sein.Thorough mixing of the components introduced into the container must also be ensured for the subsequent container. Furthermore, the container comprises at least one adjustable opening through which the melt dispersion produced in step i) can be introduced into the container, at least one further adjustable opening through which the esthetic (and any other components) can be introduced into the container, and in addition, at least one adjustable opening through which the melt dispersion produced in step ii) can be discharged from the container. This container can also be a suitable mixing unit, such as a static mixer, for example.
Die Vermischung kann aber auch durch kontinuierliches Zumischen des mindestens einen Ästhetikums in den aus dem ersten Behälter austretenden Auslaufstrom, d.h. ohne die Notwendigkeit eines separaten Behälters erfolgen. In diesem Fall ist die Öffnung, über welche das mindestens eine Ästhetikum in die Schmelzdispersion eingeleitet wird, vorzugsweise regulierbar. Auch wenn im Folgenden die Erfindung bezugnehmend auf das Vermischen in einem nachfolgenden Behälter beschrieben wird, ist selbstverständlich, dass die beschriebenen Ausführungsformen auch auf die vorstehend beschriebene Alternative des Mischens im Auslaufstrom des ersten Behälters übertragbar sind. Dabei kann das Mischungsvolumen des nachfolgenden Behälters auch das Volumen der Leitung, in welcher der Auslaufstrom aus dem ersten Behälter geführt wird, sein.However, the mixing can also take place by continuously admixing the at least one aesthetic agent into the outflow stream emerging from the first container, i.e. without the need for a separate container. In this case, the opening through which the at least one aesthetic agent is introduced into the melt dispersion can preferably be regulated. Even if the invention is described below with reference to mixing in a subsequent container, it goes without saying that the described embodiments can also be applied to the above-described alternative of mixing in the outflow stream of the first container. In this case, the mixing volume of the subsequent container can also be the volume of the line in which the outflow stream from the first container is conducted.
Ästhetikum, wie hierin verwendet, bezeichnet einen Wirk- oder Hilfsstoff, welcher bei der zur Herstellung der Schmelzdispersion in Schritt i) eingesetzten Temperatur temperaturempfindlich ist, also bei dieser Temperatur chemisch oder physikalisch desintegriert.Aesthetics, as used herein, designates an active ingredient or auxiliary which is temperature-sensitive at the temperature used to produce the melt dispersion in step i), ie chemically or physically disintegrates at this temperature.

Die Gruppe der Ästhetika umfasst dabei die Duft- und Farbstoffe.Aesthetics, as used herein, refers in particular to an active ingredient or auxiliary whose use in the melting bodies can be perceived by the consumer's senses. The group of aesthetics includes the fragrances and dyes.
Der Duftstoff wird vorzugsweise in flüssiger Form eingesetzt, beispielsweise als Parfümöl, Lösung in einem geeigneten Lösungsmittel oder als Aufschlämmung von Parfümkapseln in einem, typischerweise wasserhaltigen, Lösungsmittel. "Flüssig" wie in diesem Zusammenhang verwendet, bedeutet unter den Einsatzbedingungen flüssig, vorzugsweise bei 20°C flüssig. Gemäß einigen Ausführungsformen handelt es sich bei dem mindestens einen Duftstoff jedoch um eine weitestgehend "trockene", d.h. weitestgehend wasserfreie Komponente. Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren dadurch aus, dass der mindestens eine Duftstoff in Form von Duftstoffkapseln und/oder Parfümölen eingesetzt wird.The fragrance is preferably used in liquid form, for example as a perfume oil, a solution in a suitable solvent or as a suspension of perfume capsules in a typically aqueous solvent. "Liquid" as used in this context means liquid under the conditions of use, preferably liquid at 20°C. However, according to some embodiments, the at least one fragrance is a substantially "dry", i.e. substantially anhydrous, component. According to some embodiments, the method described herein is characterized in that the at least one fragrance is used in the form of fragrance capsules and/or perfume oils.
Der Farbstoffe wird vorzugsweise ebenfalls in flüssiger Form eingesetzt, beispielsweise in Form einer wässrigen Lösung oder Aufschlämmung.

In addition to water, the suitable dye preparations can also contain organic solvents, in particular polyols.
In einem dritten Schritt iii) erfolgt das Umformen der in Schritt ii) erhaltenen Schmelzdispersion, um feste Schmelzkörper zu erhalten. Beispielsweise über die vorangehend erwähnte Öffnung, die den Auslass der in Schritt ii) hergestellten Schmelzdispersion aus dem nachfolgenden Behälter ermöglicht, wird die hergestellte Schmelze der Umformung zugeführt.In a third step iii), the melt dispersion obtained in step ii) is reshaped in order to obtain solid melt bodies. For example, via the above-mentioned opening, which enables the melt dispersion produced in step ii) to be discharged from the downstream container, the melt produced is fed to the forming process.
Die Umformung der nach Schritt ii) erhaltenen Schmelze kann über übliche Verfahren zur Formgebung erfolgen. Geeignete Verfahren zur Formgebung sind dem Fachmann bekannt und involvieren das Abkühlen der Schmelze auf eine Temperatur, die unterhalb der Schmelztemperatur des Trägermaterials liegt, so dass die Schmelze erstarrt und dabei/dann ihre endgültige Form erhält. Beispiele schließen Pastillierung, Vertropfung, Schmelzextrusion, Prillverfahren und weitere ein. Gemäß bevorzugten Ausführungsformen erfolgt die Umformung in Schritt iii) mittels eines Kühlbandes.The melt obtained after step ii) can be shaped using customary shaping methods. Suitable shaping methods are known to those skilled in the art and involve cooling the melt to a temperature below the melting temperature of the carrier material, so that the melt solidifies and thereby/then acquires its final shape. Examples include pastillation, dripping, melt extrusion, prilling, and others. According to preferred embodiments, the forming in step iii) takes place by means of a cooling belt.

Dabei ist es weiterhin bevorzugt, dass das mindestens eine Ästhetikum mittels einer weiteren Rohrleitung aus einem entsprechenden Vorratsbehälter kontinuierlich in den Auslaufstrom des ersten Behälters einzuleiten. Hierfür eignet sich insbesondere eine flüssige Zubereitung des Ästhetikums, beispielsweise in Form einer Lösung. Die Temperatur des Ästhetikums bzw. der flüssigen Zubereitung des Ästhetikums liegt vor der Einleitung in den Auslaufstrom des ersten Behälters vorzugsweise mindestens 10°C, bevorzugt mindestens 20"C und insbesondere mindestens 30°C unterhalb der Temperatur der den Auslaufstrom bildenden Schmelzdispersion.In a preferred embodiment, the melt dispersion produced in step i) is discharged from the first container by means of a pipeline and fed to the droplet former. It is furthermore preferred that the at least one aesthetic agent is continuously introduced into the outflow stream of the first container by means of a further pipeline from a corresponding storage container. A liquid preparation of the aesthetic agent, for example in the form of a solution, is particularly suitable for this. The temperature of the esthetic or the liquid preparation of the esthetic before it is introduced into the outflow stream of the first container is preferably at least 10°C, preferably at least 20°C and in particular at least 30°C below the temperature of the melt dispersion forming the outflow stream.
Es ist weiterhin bevorzugt, nach der Einleitung des Ästhetikums in die Schmelzdispersion das resultierende Gemisch in der Rohrleitung zu vermischen. Vorzugsweise erfolgt die Vermischung mittels eines statischen Mischers, welcher sich in der Rohrleitung in Fließrichtung der Schmelzdispersion hinter dem Zutrittspunkt des Ästhetikums und vor dem Eintrittspunkt des Gemisches in den Tropfenformer befindet.It is further preferred to mix the resulting mixture in the pipeline after the introduction of the aesthetic into the melt dispersion. The mixing preferably takes place by means of a static mixer, which is located in the pipeline in the direction of flow of the melt dispersion behind the entry point of the esthetic and before the entry point of the mixture into the droplet former.

Aus der Rohrleitung tritt das Gemisch aus Schmelzdispersion und Ästhetikum in den Tropfenformer mit rotierender, gelochter Außentrommel ein. Der Abschnitt der Rohrleitung, welcher sich innerhalb der Trommel des Tropfenformers befindet wird nachfolgend zur Unterscheidung von der vorherigen Rohrleitung als Zuführkanal bezeichnet. Der Zuführkanal erstreckt sich vorzugsweise über mindestens 80%, besonders bevorzugt über mindestens 90% und insbesondere über 100% der Länge der Trommel des Tropfenformers.The mixture of melt dispersion and aesthetics enters the droplet former with rotating, perforated outer drum from the pipeline.

The feed channel preferably extends over at least 80%, particularly preferably over at least 90% and in particular over 100% of the length of the drum of the gob former.
Das in den Zuführkanal eingeleitete Gemisch tritt aus dem Zuführkanal vorzugsweise durch an der Unterseite des Zuführkanals befindliche Bohrungen aus dem Zuführkanal auf eine Verteiler- oder Düsenleiste aus, welche ihrerseits an der Innenseite der rotierenden, gelochten Außentrommel anliegt. Das Gemisch durchläuft die Verteiler- oder Düsenleiste und wird nachfolgend aus den Löcher der rotierenden Außentrommel auf ein unterhalb dieser Löcher befindliches Stahlband ausgebracht. Der Abstand zwischen der Außenseite der rotierenden, gelochten Außentrommel und der Oberfläche des Stahlbandes beträgt vorzugsweise zwischen 5 und 20 mm.The mixture introduced into the feed channel exits the feed channel, preferably through bores located on the underside of the feed channel, from the feed channel onto a distributor or nozzle bar, which in turn bears against the inside of the rotating, perforated outer drum. The mixture runs through the distributor or nozzle bar and is then discharged from the holes in the rotating outer drum onto a steel belt below these holes. The distance between the outside of the rotating, perforated outer drum and the surface of the steel strip is preferably between 5 and 20 mm.
Zur weiteren Verbesserung der Durchmischung von Schmelzdispersion und Ästhetikum und zur Verhinderung oder Minimierung von Sedimentation kann im Zuführkanal ein weiterer Mischer angeordnet sein. Bevorzugt handelt es sich dabei um einen dynamischen Mischer, beispielsweise eine innerhalb des Zuführkanals drehbar angeordnete Wendel.To further improve the mixing of melt dispersion and esthetic and to prevent or minimize sedimentation, a further mixer can be arranged in the feed channel. This is preferably a dynamic mixer, for example a spiral arranged rotatably within the feed channel.
Um die Temperaturbelastung des Ästhetikums zu minimieren beträgt die Verweilzeit des Gemisches aus Schmelzdispersion und Ästhetikum in der Rohrleitung bis zum Austritt aus der rotierenden, gelochten Außentrommel des Tropfenformers vorzugsweise weniger als 20 Sekunden, besonders bevorzugt weniger als 10 Sekunden und insbesondere zwischen 0,5 und 5 Sekunden.In order to minimize the temperature load on the aesthetics, the residence time of the mixture of melt dispersion and aesthetics in the pipeline until it exits the rotating, perforated outer drum of the drop former is preferably less than 20 seconds, particularly preferably less than 10 seconds and in particular between 0.5 and 5 seconds.
Die Viskosität (Texas Instruments AR-G2 Rheometer; Platte/Platte, 4cm Durchmesser, 1100µm Spalte; Scherrate 10/1sec) des Gemisches bei Austritt aus der rotierenden, gelochten Außentrommel beträgt vorzugsweise zwischen 1000 und 10000 mPas.The viscosity (Texas Instruments AR-G2 rheometer; plate/plate, 4 cm diameter, 1100 μm gap; shear rate 10/1 sec) of the mixture when it emerges from the rotating, perforated external drum is preferably between 1000 and 10000 mPas.
Auf dem Stahlband werden die aus dem Tropfenformer ausgebrachten Tropfen des Gemisches zu festen Schmelzkörpern verfestigt. Die Zeitdauer zwischen dem Auftropfen des Gemisches auf das Stahlband und dem vollständigen Verfestigen der Mischung beträgt vorzugsweise zwischen 5 und 60 Sekunden, besonders bevorzugt zwischen 10 und 50 Sekunden und insbesondere zwischen 20 und 40 Sekunden.The droplets of the mixture discharged from the droplet former are solidified on the steel belt to form solid melted bodies. The time between the dropping of the mixture onto the steel strip and the complete solidification of the mixture is preferably between 5 and 60 seconds, particularly preferably between 10 and 50 seconds and in particular between 20 and 40 seconds.
Die Verfestigung der Mischung wird vorzugsweise durch eine Kühlung unterstützt und beschleunigt. Die Kühlung der auf das Stahlband ausgebrachten Tropfen kann direkt oder indirekt erfolgen. Als direkte Kühlung ist beispielsweise eine Kühlung mittels Kaltluft einsetzbar. Bevorzugt ist jedoch die indirekte Kühlung der Tropfen durch Kühlung der Unterseite des Stahlbandes mittels Kaltwasser.The solidification of the mixture is preferably supported and accelerated by cooling. The droplets applied to the steel strip can be cooled directly or indirectly. Cooling by means of cold air, for example, can be used as direct cooling. However, indirect cooling of the droplets by cooling the underside of the steel strip with cold water is preferred.

"Water-soluble" and "water-dispersible" have the meanings given above.
In verschiedenen bevorzugten Ausführungsformen ist das mindestens eine Trägerpolymer ausgewählt aus Polyalkylenglykolen.In various preferred embodiments, the at least one carrier polymer is selected from polyalkylene glycols.
Im Kontext der vorliegenden Erfindung sind solche Polyalkylenglykole geeignet, die ein mittleres Molekulargewicht (Mn) von >1000 g/mol, insbesondere >1500 g/mol, vorzugsweise ein mittleres Molekulargewicht zwischen 3.000 und 15.000, noch bevorzugter ein mittleres Molekulargewicht zwischen 4.000 und 13.000, weiter bevorzugt ein mittleres Molekulargewicht zwischen 4000 und 6000, 6000 und 8000 oder 9.000 und 12.000 und insbesondere bevorzugt von etwa 4000 oder etwa 6000 g/mol aufweisen.In the context of the present invention, those polyalkylene glycols are suitable that have an average molecular weight (M n ) of >1000 g/mol, in particular >1500 g/mol, preferably an average molecular weight between 3,000 and 15,000, more preferably an average molecular weight between 4,000 and 13,000 , more preferably have an average molecular weight between 4000 and 6000, 6000 and 8000 or 9000 and 12000 and particularly preferably of about 4000 or about 6000 g / mol.
Wenn im Rahmen dieser Anmeldung von "mittlerem Molekulargewicht von Polyalkylenglykolen" gesprochen wird, so beziehen sich diese Angaben jeweils auf die zahlenmittleren Molekulargewichte (Mn), die sich rechnerisch aus der OH-Zahl gemessen gemäß DIN 53240-1:2012-07 ergeben.When “average molecular weight of polyalkylene glycols” is mentioned in this application, this information relates to the number-average molecular weights (M n ) which are calculated from the OH number measured according to DIN 53240-1:2012-07.
Gemäß der vorliegenden Erfindung sind insbesondere solche Polyalkylglykole geeignet, die einen Schmelzpunkt zwischen 40 °C und 90 °C aufweisen, insbesondere im Bereich von 45 bis 70°C. Beispiele für Polyalkylenglykole, die im Kontext der vorliegenden Erfindung geeignet sind, sind Polypropylenglykol und Polyethylenglykol.According to the present invention, those polyalkyl glycols are particularly suitable which have a melting point between 40.degree.

Gemäß einigen Ausführungsformen handelt es sich bei dem mindestens einen Trägerpolymer vorzugsweise um Polyethylenglykol.According to some embodiments, the at least one carrier polymer is preferably polyethylene glycol.
In einigen Ausführungsformen handelt es sich bei dem mindestens einen Trägerpolymer um ein Polyethylenglykol mit einem mittleren Molekulargewicht (Mn) von >1500 g/mol, vorzugsweise einem mittleren Molekulargewicht zwischen 3.000 und 15.000, noch bevorzugter mit einem mittleren Molekulargewicht zwischen 4.000 und 13.000, weiter bevorzugt ein mittleres Molekulargewicht zwischen 4000 und 6000, 6000 und 8000 oder 9.000 und 12.000 und insbesondere bevorzugt von etwa 4000 oder etwa 6000 g/mol aufweisen. In einigen Ausführungsformen zeichnet sich ein solches Polyethylenglykol durch einen Schmelzpunkt im Bereich von 45 bis 70°C, vorzugsweise 50 bis 65°C aus, noch bevorzugter 50 bis 60°C. "Etwa" oder "ungefähr", wie hierin im Zusammenhang mit einem Zahlenwert verwendet, bedeutet den Zahlenwert ±10%, vorzugsweise ±5%. Ein Molekulargewicht von etwa 6000 g/mol bedeutet somit 5400-6600 g/mol, vorzugsweise 5700-6300 g/mol.In some embodiments, the at least one carrier polymer is a polyethylene glycol with an average molecular weight (M n ) of >1500 g/mol, preferably an average molecular weight between 3,000 and 15,000, more preferably with an average molecular weight between 4,000 and 13,000 preferably have an average molecular weight between 4000 and 6000, 6000 and 8000 or 9000 and 12000 and particularly preferably of about 4000 or about 6000 g/mol. In some embodiments, a such polyethylene glycol is characterized by a melting point in the range of 45 to 70°C, preferably 50 to 65°C, more preferably 50 to 60°C. "About" or "about" as used herein in connection with a numerical value means the numerical value ±10%, preferably ±5%. A molecular weight of about 6000 g/mol thus means 5400-6600 g/mol, preferably 5700-6300 g/mol.
In verschiedenen Ausführungsformen wird das mindestens eine Trägerpolymer in einer Menge eingesetzt, dass der resultierende Schmelzkörper, d.h. die Duftstoffpastille von 30 bis 95 Gew.-%, vorzugsweise von 35 bis 85 Gew.-%, beispielsweise 40 bis 80 oder 40 bis 78 Gew.-%, basierend auf dem Gesamtgewicht des Schmelzkörpers, des Trägerpolymers enthält.In various embodiments, the at least one carrier polymer is used in an amount such that the resulting melted body, i.e. the fragrance pastille, contains from 30 to 95% by weight, preferably from 35 to 85% by weight, for example 40 to 80 or 40 to 78% by weight. -%, based on the total weight of the melt body, of the carrier polymer.
Alternativ zu den zuvor beschriebenen polymeren Trägermaterialien können als Trägermaterialien auch spezifische Salze eingesetzt werden. Bei diesen spezifischen Salzen handelt es sich insbesondere um wasserhaltige Salze, deren Wasserdampf-Partialdruck bei einer bestimmten Temperatur im Bereich von 30 bis 100°C dem H2O-Partialdruck der gesättigten Lösung dieses Salzes entspricht.As an alternative to the polymeric carrier materials described above, specific salts can also be used as carrier materials. These specific salts are, in particular, water-containing salts whose water vapor partial pressure at a specific temperature in the range from 30 to 100° C. corresponds to the H 2 O partial pressure of the saturated solution of this salt.
Der Schmelzkörper, wie er hierin beschrieben wird, wird aus einer Lösung des Trägermaterials in dem in der Zusammensetzung enthaltenem Wasser/Kristallwasser hergestellt, wobei hierin für eine solche Lösung auch der Begriff "Schmelze" im Gegensatz zu der etablierten Verwendung verwendet wird, um den Zustand zu bezeichnen, bei dem sich das Trägermaterial durch die Abspaltung von Wasser im eigenen Kristallwasser löst und so eine Flüssigkeit bildet. Der Begriff "Schmelze", wie hierin verwendet, bezeichnet somit den flüssigen Zustand der Zusammensetzung, der bei Überschreiten der Temperatur entsteht, bei welcher das Trägermaterial Kristallwasser abspaltet und sich dann in dem, in der Zusammensetzung enthaltenem Wasser löst. Die entsprechende Dispersion, die die hierin beschriebenen (Fest)Stoffe dispergiert in der Schmelze des Trägermaterials enthält, ist somit ebenfalls Gegenstand der Erfindung. Wenn also im Folgenden auf die feste, partikuläre Zusammensetzung Bezug genommen wird, ist immer auch die entsprechende Schmelze/Schmelzdispersion, aus welcher dieser erhältlich ist, erfasst. Da sich diese mit Ausnahme des Aggregatzustands von der Zusammensetzung her nicht unterscheiden, werden die Begriffe hierin synonym verwendet.The melted body, as described herein, is produced from a solution of the carrier material in the water/crystal water contained in the composition, the term "melt" being used here for such a solution, in contrast to the established usage to describe the state in which the carrier material dissolves in its own water of crystallization due to the elimination of water and thus forms a liquid. The term "melt", as used herein, thus designates the liquid state of the composition, which occurs when the temperature is exceeded at which the carrier material splits off water of crystallization and then dissolves in the water contained in the composition. The corresponding dispersion, which contains the (solid) substances described herein dispersed in the melt of the carrier material, is therefore also a subject of the invention. So when reference is made below to the solid, particulate composition, the corresponding melt/melt dispersion from which it can be obtained is always included. Since these do not differ in composition, with the exception of the physical state, the terms are used synonymously here.
Ein bevorzugtes Trägermaterial zeichnet sich dadurch aus, dass es ausgewählt ist aus wasserhaltigen Salzen, deren Wasserdampf-Partialdruck bei einer Temperatur im Bereich von 30 bis 100°C dem H2O-Partialdruck der gesättigten Lösung dieses Salzes bei derselben Temperatur entspricht. Dies führt dazu, dass sich das entsprechende wasserhaltige Salz, hierin auch als "Hydrat" bezeichnet, beim Erreichen oder Überschreiten dieser Temperatur im eigenen Kristallwasser löst und dadurch von einem festen in einen flüssigen Aggregatzustand übergeht. Vorzugsweise zeigen die erfindungsgemäßen Trägermaterialien dieses Verhalten bei einer Temperatur im Bereich von 40 bis 90°C, besonders bevorzugt zwischen 50 und 85°C, noch bevorzugter zwischen 55 und 80°C.A preferred carrier material is characterized in that it is selected from water-containing salts whose water vapor partial pressure at a temperature in the range from 30 to 100° C. corresponds to the H 2 O partial pressure of the saturated solution of this salt at the same temperature. This means that the corresponding water-containing salt, also referred to herein as "hydrate", dissolves in its own water of crystallization when this temperature is reached or exceeded and thereby changes from a solid to a liquid state of aggregation. The carrier materials according to the invention preferably show this behavior in a Temperature in the range 40 to 90°C, more preferably between 50 and 85°C, even more preferably between 55 and 80°C.
Zu den zuvor beschriebenen wasserlöslichen Trägermaterialien aus der Gruppe wasserhaltiger Salze zählen insbesondere das Natriumacetat-Trihydrat (Na(CH3COO) · 3H2O), das Glaubersalz (Na2SO4 · 10H2O) sowie das Trinatriumphosphat Dodecahydrat (Na3PO4 · 12 H2O).The water-soluble carrier materials from the group of water-containing salts described above include, in particular, sodium acetate trihydrate (Na(CH 3 COO) 3H 2 O), Glauber's salt (Na 2 SO 4 10H 2 O) and trisodium phosphate dodecahydrate (Na 3 PO 4 x 12H2O ).
Ein besonders geeignetes Hydrat ist Natriumacetat-Trihydrat (Na(CH3COO) · 3H2O), da es sich in dem besonders bevorzugten Temperaturbereich von 55 bis 80°C, konkret bei etwa 58°C, im eigenen Kristallwasser löst. Das Natriumacetat-Trihydrat kann direkt als solches eingesetzt werden, es ist aber auch alternativ der Einsatz von wasserfreiem Natriumacetat in Kombination mit freiem Wasser möglich, wobei sich das Trihydrat dann in situ bildet. In solchen Ausführungsformen wird das Wasser in unter- oder überstöchiometrischer Menge bezogen auf die Menge, die notwendig ist, um das gesamte Natriumacetat in Natriumacetat-Trihydrat zu überführen, eingesetzt, vorzugsweise in einer Menge von mindestens 60 Gew.-%, vorzugsweise mindestens 70 Gew.-%, noch bevorzugter mindestens 80 Gew.-%, am meisten bevorzugt 90 Gew.-%, 100 Gew.-% oder mehr, der Menge, die theoretisch erforderlich ist, um das gesamte Natriumacetat in Natriumacetat-Trihydrat (Na(CH3COO) · 3H2O) zu überführen. Besonders bevorzugt ist der überstöchiometrische Einsatz von Wasser. Bezogen auf die erfindungsgemäßen Zusammensetzungen bedeutet das, dass wenn (wasserfreies) Natriumacetat allein oder in Kombination mit einem Hydrat davon, vorzugsweise dem Trihydrat, eingesetzt wird, ebenfalls Wasser eingesetzt wird, wobei die Menge an Wasser mindestens der Menge entspricht, die stöchiometrisch notwendig wäre, um zu gewährleisten, dass mindestens 60 Gew.-% der Gesamtmenge aus Natriumacetat und dessen Hydraten, vorzugsweise mindestens 70 Gew.-%, weiter bevorzugt mindestens 80 Gew.-%, noch weiter bevorzugt mindestens 90 Gew.-%, am meisten bevorzugt mindestens 100 Gew.-%, in Form von Natriumacetat-Trihydrat vorliegt. Wie bereits oben beschrieben ist es besonders bevorzugt, dass die Menge an Wasser die Menge, die theoretisch notwendig wäre, um das gesamte Natriumacetat in das korrespondierende Trihydrat zu überführen, übersteigt. Dies bedeutet beispielsweise, dass eine Zusammensetzung, die 50 Gew.-% wasserfreies Natriumacetat und kein Hydrat davon enthält, mindestens 19,8 Gew.-% Wasser (60% von 33 Gew.-%, die theoretisch notwendig wären, um das gesamte Natriumacetat in das Trihydrat zu überführen), enthält.A particularly suitable hydrate is sodium acetate trihydrate (Na(CH 3 COO).3H 2 O), since it dissolves in its own water of crystallization in the particularly preferred temperature range of 55 to 80° C., specifically at about 58° C. The sodium acetate trihydrate can be used directly as such, but alternatively the use of anhydrous sodium acetate in combination with free water is also possible, the trihydrate then being formed in situ . In such embodiments, the water is used in less than or more than the stoichiometric amount based on the amount necessary to convert all of the sodium acetate to sodium acetate trihydrate, preferably in an amount of at least 60% by weight, preferably at least 70% by weight %, more preferably at least 80%, most preferably 90%, 100% or more by weight of the amount theoretically required to convert all the sodium acetate to sodium acetate trihydrate (Na(CH 3 COO) · 3H 2 O). The more than stoichiometric use of water is particularly preferred. Based on the compositions according to the invention, this means that if (anhydrous) sodium acetate is used alone or in combination with a hydrate thereof, preferably the trihydrate, water is also used, the amount of water being at least the amount that would be stoichiometrically necessary. to ensure that at least 60% by weight of the total amount of sodium acetate and its hydrates, preferably at least 70% by weight, more preferably at least 80% by weight, even more preferably at least 90% by weight, most preferably at least 100% by weight, is in the form of sodium acetate trihydrate. As already described above, it is particularly preferred that the amount of water exceeds the amount that would theoretically be necessary to convert all of the sodium acetate into the corresponding trihydrate. This means, for example, that a composition containing 50% by weight anhydrous sodium acetate and no hydrate thereof contains at least 19.8% by weight water (60% of the 33% by weight that would theoretically be necessary to contain all the sodium acetate into the trihydrate).
Alle im Folgenden beschriebenen Ausführungsformen sind explizit mit beiden der vorgenannten Alternativen kombinierbar.All of the embodiments described below can be explicitly combined with both of the aforementioned alternatives.
In verschiedenen Ausführungsformen wird das mindestens eine Trägermaterial aus der Gruppe der wasserhaltigen Salzen, deren Wasserdampf-Partialdruck bei einer Temperatur im Bereich von 30 bis 100°C dem H2O-Partialdruck der gesättigten Lösung dieses Salzes bei derselben Temperatur entspricht, in einer Menge eingesetzt, dass der resultierende Schmelzkörper, von 30 bis 95 Gew.-%, vorzugsweise von 40 bis 90 Gew.-%, beispielsweise 45 bis 90 Gew.-%, basierend auf dem Gesamtgewicht des Schmelzkörpers, des Trägermaterials enthält.In various embodiments, the at least one carrier material is from the group of water-containing salts whose water vapor partial pressure at a temperature in the range from 30 to 100° C. is the H 2 O partial pressure of the saturated solution of this salt at the same temperature corresponds, used in an amount that the resulting melted body contains from 30 to 95% by weight, preferably from 40 to 90% by weight, for example 45 to 90% by weight, based on the total weight of the melted body, of the carrier material .

Wie dargelegt, umfasst die in Schritt i) herzustellende Schmelzdispersion neben dem mindestens einen Trägermaterial mindestens einen Feststoff, beispielsweise einen Füllstoff. Damit sichergestellt ist, dass dieser mindestens eine Feststoff in der gewünschten Partikelgröße in den ersten Behälter eingebracht wird, kann es von Vorteil sein, wenn dem ersten Behälter zu diesem Zwecke mindestens eine Siebvorrichtung vorgeschaltet ist, die der mindestens eine Feststoff durchläuft, bevor er in den ersten Behälter eingebracht wird. Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren folglich dadurch aus, dass der mindestens eine Feststoff in einem Schritt i) vorgeschalteten Schritt b) mindestens eine Siebvorrichtung durchläuft. Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren dadurch aus, dass der mindestens eine Feststoff ausgewählt ist aus der Gruppe bestehend aus Polysacchariden, wie Stärke, insbesondere Maisstärke, Kieselsäuren, wie pyrogener Kieselsäure, Silikaten, insbesondere Alkalisilikaten, Sulfaten, insbesondere Alkalimetallsulfaten, wie Natriumsulfat, Phosphaten, insbesondere Alkalimetallphosphaten, wie Pentanatrium- bzw. Pentakaliumtriphosphat, Halogeniden und Carbonaten, insbesondere Alkalicarbonaten, wie beispielsweise Natriumcarbonat.As explained, the melt dispersion to be produced in step i) comprises at least one solid, for example a filler, in addition to the at least one carrier material. In order to ensure that this at least one solid is introduced into the first container in the desired particle size, it can be advantageous if at least one screening device is installed upstream of the first container for this purpose, through which the at least one solid passes before it enters the first container is introduced. According to some embodiments, the method described herein is therefore characterized in that the at least one Solid in a step i) upstream step b) passes through at least one screening device. According to some embodiments, the method described herein is characterized in that the at least one solid is selected from the group consisting of polysaccharides, such as starch, in particular corn starch, silicic acids, such as pyrogenic silicic acid, silicates, in particular alkali silicates, sulfates, in particular alkali metal sulfates such as sodium sulfate , phosphates, especially alkali metal phosphates, such as pentasodium or pentapotassium triphosphate, halides and carbonates, especially alkali metal carbonates, such as sodium carbonate.
Der mindestens eine Feststoff kann in einer Menge von 0,01 bis 30 Gew.-%, vorzugsweise 1 bis 20 Gew.%, bezogen auf das Gesamtgewicht der Schmelzkörper, eingesetzt werden. Der mindestens eine Feststoff weist eine Schmelztemperatur auf, die über der Schmelztemperatur des Trägermaterials und der in dem beschriebenen Verfahren herrschenden Temperatur liegt, um so eine Schmelzdispersion bereitzustellen.The at least one solid can be used in an amount of 0.01 to 30% by weight, preferably 1 to 20% by weight, based on the total weight of the melted bodies. The at least one solid has a melting temperature that is above the melting temperature of the carrier material and the temperature prevailing in the method described, in order to provide a melt dispersion in this way.
Wie ebenfalls bereits voranstehend erwähnt, besteht ein weiterer Vorteil des wie hierin beschriebenen Verfahrens darin, dass die eingesetzten Ästhetika eine vergleichsweise geringe Verweildauer bei erhöhten Temperaturen, d.h., Temperaturen entsprechend der Schmelztemperatur des jeweiligen Trägermaterials, hat. Da die Duft- und Farbkomponente temperaturempfindlich ist, kann durch eine geringe Verweildauer bei erhöhten Temperaturen die Beduftungs- und Farbqualität besagter Komponente verbessert werden, wodurch ein überlegenes Endprodukt erzielt wird. Gemäß dem vorliegenden Verfahren wird dieser Vorteil gewährleistet, indem die Duft- und/oder Farbkomponente erst unmittelbar vor der Umformung mit dem aufgeschmolzenen Material in Berührung kommt.As also already mentioned above, a further advantage of the method as described herein is that the aesthetics used have a comparatively short residence time at elevated temperatures, i.e. temperatures corresponding to the melting temperature of the respective carrier material. Because the fragrance and color component is temperature sensitive, a short residence time at elevated temperatures can improve the fragrance and color quality of said component, resulting in a superior end product. According to the present method, this advantage is ensured in that the fragrance and/or color component only comes into contact with the melted material immediately before the forming process.
Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren des Weiteren dadurch aus, dass, indem der nachfolgende Behälter bzw. die Leitung, in welchem die in Schritt i) hergestellte Schmelzdispersion mit dem mindestens einen Ästhetikum (sowie ggf. weiteren Komponenten) vermischt wird, ein vergleichsweise geringes Fassungsvolumen aufweist. Auf diese Weise werden, im Falle eines Anlagenstillstandes, nur vergleichsweise geringe Mengen Duftstoff durch ein übermäßig langes Verweilen bei erhöhten Temperaturen temperaturgeschädigt und es entstehen folglich nur geringe Mengen Verschnittmaterial. Insbesondere weist der nachfolgende in Schritt ii) eingesetzte Behälter, wie hierin beschrieben, ein vergleichsweise geringes Fassungsvolumen auf, wenn sein Fassungsvolumen maximal 1500 I, vorzugsweise maximal 1300 I, insbesondere maximal 1000 I, am meisten bevorzugt maximal 200 I misst. Gemäß einigen Ausführungsformen zeichnet sich das hierin beschriebene Verfahren dadurch aus, dass der Behälter aus Schritt ii) ein statischer oder dynamischer Mixer mit einem Fassungsvolumen von ≤200 l oder ein Rührkessel mit einem Fassungsvolumen von ≤1200 l ist.According to some embodiments, the method described herein is further characterized in that the subsequent container or the line in which the melt dispersion produced in step i) is mixed with the at least one aesthetic agent (and optionally other components), a has a comparatively small capacity. In this way, in the event of a plant standstill, only comparatively small amounts of fragrance are thermally damaged by staying at elevated temperatures for an excessively long time, and consequently only small amounts of waste material are produced. In particular, the subsequent container used in step ii), as described herein, has a comparatively small capacity if its capacity is at most 1500 l, preferably at most 1300 l, in particular at most 1000 l, most preferably at most 200 l. According to some embodiments, the method described herein is characterized in that the container from step ii) is a static or dynamic mixer with a capacity of ≦200 l or a stirred tank with a capacity of ≦1200 l.
Eine weitere Komponente der wie hierin beschrieben hergestellten Schmelzkörper ist mindestens ein Ästhetikum, Bevorzugte Ästhetika sind die Duft- und Farbstoffe.A further component of the melting bodies produced as described herein is at least one esthetic. Preferred esthetics are the fragrances and colorants.
Bei einem Duftstoff handelt es sich um eine den Geruchsinn anregende, chemische Substanz. Um den Geruchssinn anregen zu können, sollte die chemische Substanz zumindest teilweise in der Luft verteilbar sein, d.h. der Duftstoff sollte bei 25°C zumindest in geringem Maße flüchtig sein. Ist der Duftstoff nun sehr flüchtig, klingt die Geruchsintensität dann schnell wieder ab. Bei einer geringeren Flüchtigkeit ist der Gerucheindruck jedoch nachhaltiger, d.h. er verschwindet nicht so schnell. In einer Ausführungsform weist der Duftstoff daher einen Schmelzpunkt auf, der im Bereich von -100°C bis 100°C, bevorzugt von -80°C bis 80°C, noch bevorzugter von -20°C bis 50°C, insbesondere von -30°C bis 20°C liegt. In einer weiteren Ausführungsform weist der Duftstoff einen Siedepunkt auf, der im Bereich von 25°C bis 400°C, bevorzugt von 50°C bis 380°C, mehr bevorzugt von 75°C bis 350°C, insbesondere von 100°C bis 330°C liegt.A fragrance is a chemical substance that stimulates the sense of smell. In order to be able to stimulate the sense of smell, the chemical substance should be at least partially airborne, i.e. the fragrance should be at least slightly volatile at 25°C. If the fragrance is now very volatile, the odor intensity then quickly fades away. With a lower volatility, however, the odor impression is more lasting, i.e. it does not disappear as quickly. In one embodiment, the fragrance therefore has a melting point in the range from -100°C to 100°C, preferably from -80°C to 80°C, more preferably from -20°C to 50°C, in particular from - 30°C to 20°C. In a further embodiment, the fragrance has a boiling point which is in the range from 25° C. to 400° C., preferably from 50° C. to 380° C., more preferably from 75° C. to 350° C., in particular from 100° C. to 330°C.
Insgesamt sollte eine chemische Substanz eine bestimmte Molekülmasse nicht überschreiten, um als Duftstoff zu fungieren, da bei zu hoher Molekülmasse die erforderliche Flüchtigkeit nicht mehr gewährleitstet werden kann. In einer Ausführungsform weist der Duftstoff eine Molekülmasse von 40 bis 700 g/mol, noch bevorzugter von 60 bis 400 g/mol auf.Overall, a chemical substance should not exceed a specific molecular mass in order to function as a fragrance, since the required volatility can no longer be guaranteed if the molecular mass is too high. In one embodiment, the fragrance has a molecular mass of 40 to 700 g/mol, more preferably 60 to 400 g/mol.
Der Geruch eines Duftstoffes wird von den meisten Menschen als angenehm empfunden und entspricht häufig dem Geruch nach beispielsweise Blüten, Früchten, Gewürzen, Rinde, Harz, Blättern, Gräsern, Moosen und Wurzeln. So können Duftstoffe auch dazu verwendet werden, um unangenehme Gerüche zu überlagern oder aber auch um einen nicht riechenden Stoff mit einem gewünschten Geruch zu versehen. Als Duftstoffe können einzelne Riechstoffverbindungen, z.B. die synthetischen Produkte vom Typ der Ester, Ether, Aldehyde, Ketone, Alkohole und Kohlenwasserstoffe verwendet werden.The smell of a fragrance is perceived as pleasant by most people and often corresponds to the smell of, for example, blossoms, fruits, spices, bark, resin, leaves, grass, moss and roots. Fragrances can also be used to mask unpleasant odors or to provide a non-smelling substance with a desired smell. Individual fragrance compounds, for example synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type, can be used as fragrances.

Die Verwendung von Polysiloxanen und/oder kationischen Polymeren als Textil-pflegende Verbindung in der Schmelzkörper-Zusammensetzung ist vorteilhaft, da diese nicht nur einen weichmachenden Effekt zeigen, sondern auch den Parfümeindruck auf der Wäsche verstärken. Die Verwendung von weichmachenden Tonen als Textil-pflegende Verbindung in der Schmelzkörper-Zusammensetzung ist vorteilhaft, da diese zusätzlich einen Wasser-enthärtenden Effekt aufweisen und so beispielsweise Kalkablagerungen auf der Wäsche verhindert werden können. Um eine optimale Leistung zu erzielen, kann es bevorzugt sein, dass eine Schmelzkörper-Zusammensetzung eine Kombination von wenigstens zwei Textil-pflegenden Verbindungen enthält.The use of polysiloxanes and/or cationic polymers as a textile-care compound in the hot-melt composition is advantageous, since these not only have a softening effect, but also enhance the perfume impression on the laundry. The use of softening clays as a textile-care compound in the hot-melt composition is advantageous since they also have a water-softening effect and can thus, for example, prevent limescale deposits on the laundry. In order to achieve optimal performance, it may be preferred that a hot melt composition contains a combination of at least two fabric conditioning compounds.
Wenn die erfindungsgemäß hergestellte Schmelzkörper-Zusammensetzung derartige Textil-pflegende Verbindungen enthält, wird sie insbesondere als Textilpflegemittel oder Weichspüler oder als Bestandteil eines solchen Mittels oder auch als Bestandteil eines Waschmittels eingesetzt.If the hot-melt composition produced according to the invention contains such textile care compounds, it is used in particular as a textile care agent or fabric softener or as a component of such an agent or as a component of a detergent.
Ein solcher Weichspüler kann im Hauptwaschgang eines automatischen Wasch- oder Reinigungsverfahrens eingesetzt werden. Die Schmelzkörper-Zusammensetzung kann beispielsweise zusammen mit dem Wasch- oder Reinigungsmittel in die Trommel oder die Einspülkammer einer Waschmaschine gegeben werden. Dies hat den Vorteil, dass kein zusätzlicher Spülgang notwendig ist und keine unschönen Ablagerungen in der Einspülkammer auftretenSuch a fabric softener can be used in the main wash cycle of an automatic washing or cleaning process. The melted body composition can, for example, be added to the drum or the dispensing compartment of a washing machine together with the detergent or cleaning agent. This has the advantage that no additional rinse cycle is necessary and no unsightly deposits in the dispenser compartment
Weiterhin kann eine wie hierin beschrieben hergestellte feste Schmelzkörper-Zusammensetzung im Waschgang eines Wäschereinigungsverfahrens eingesetzt werden und so die Textil-pflegende Verbindung und das Parfüm bereits direkt zu Beginn des Waschverfahrens zur Wäsche transportieren, um so ihr volles Potential entfalten zu können. Weiterhin ist diese feste Schmelzkörper-Zusammensetzung einfacher und besser zu handhaben als flüssige Zusammensetzungen, da keine Tropfen am Flaschenrand zurückbleiben, die bei der anschließenden Lagerung der Flasche zu Rändern auf dem Untergrund oder zu unschönen Ablagerungen im Bereich des Verschlusses führen. Dasselbe gilt für den Fall, dass bei der Dosierung etwas von der Schmelzkörper-Zusammensetzung versehentlich verschüttet wird. Die verschüttete Zusammensetzung kann auch einfacher und sauberer entfernt werden.Furthermore, a solid melt composition prepared as described herein can be used in the wash cycle of a laundry cleaning process and thus the fabric care compound and perfume can be applied to the laundry right at the start of the laundry process transported in order to be able to develop their full potential. Furthermore, this solid melted body composition is easier and better to handle than liquid compositions, since no drops remain on the edge of the bottle, which lead to edges on the substrate or unsightly deposits in the area of the closure during subsequent storage of the bottle. The same applies in the event that some of the melt body composition is accidentally spilled during dosing. The spilled composition can also be cleaned up more easily and cleanly.

In verschiedenen Ausführungsformen ist es bevorzugt, dass der Schmelzkörper neben dem Trägermaterial, dem mindestens einen Feststoff, dem mindestens einen Ästhetikum keine weiteren Verbindungen in nennenswerter Menge (d.h. in Mengen >1 Gew.-% bezogen auf das Gesamtgewicht des Schmelzkörpers) enthält.In various embodiments, it is preferred that the melting body contains no other compounds in significant amounts (ie in amounts >1% by weight based on the total weight of the melting body) in addition to the carrier material, the at least one solid, the at least one aesthetic agent.
Ein weiterer Gegenstand ist ein parfüm- und farbstoffhaltiger Schmelzkörper, der nach einem wie hierin beschriebenen Verfahren hergestellt wurde. Ein besonderer Vorteil eines solchen Schmelzkörpers ist die verbesserte Duft- oder Farbqualität, die durch eine vergleichsweise geringe Verweilzeit der Duft- oder Farbkomponente bei erhöhten Temperaturen, d.h. Temperaturen entsprechend der Schmelztemperatur des jeweiligen Trägermaterials, gewährleistet wird.Another object is a perfume and dye containing melt body made by a process as described herein. A particular advantage of such a melted body is the improved scent or color quality, which is ensured by a comparatively short dwell time of the scent or color component at elevated temperatures, i.e. temperatures corresponding to the melting temperature of the respective carrier material.
Bei der Hauptkomponente der wie hierin beschrieben hergestellten Schmelzkörper handelt es sich um mindestens ein wasserlösliches oder wasserdispergierbares Trägermaterial, wie bereits oben beschrieben.The main component of the melted bodies produced as described herein is at least one water-soluble or water-dispersible carrier material, as already described above.
Bei den Ästhetika-haltigen Schmelzkörpern, die gemäß einem Verfahren wie hierin beschrieben hergestellt wurde, handelt es sich um Schmelzkörper, die bei Raumtemperatur und Temperaturen bis 30°C, vorzugsweise bis 40°C fest sind.The Aesthetics-containing fused bodies produced according to a method as described herein are fused bodies which are solid at room temperature and temperatures up to 30°C, preferably up to 40°C.
Erwähnt sei auch die Verwendung der wie hierin beschrieben hergestellten Schmelzkörper als Textilpflegemittel, vorzugsweise Beduftungsmittel und/oder Weichspüler, zum Beduften und/oder Konditionieren von textilen Flächengebilden. Die Schmelzkörper können dabei ein Textilbehandlungsmittel, wie beispielsweise ein Weichspüler oder ein Teil eines solchen Mittels sein.Mention should also be made of the use of the melt bodies produced as described herein as textile care agents, preferably scenting agents and/or fabric softeners, for scenting and/or conditioning textile fabrics. The melted bodies can be a textile treatment agent, such as a fabric softener, or part of such an agent.
Ferner offenbart ein Wasch- oder Reinigungsmittel, umfassend die erfindungsgemäßen Schmelzkörper.Furthermore, a washing or cleaning agent is disclosed, comprising the melting bodies according to the invention.
Durch das Einbringen der erfindungsgemäß hergestellten Schmelzkörper in ein Wasch- oder Reinigungsmittel steht dem Verbraucher ein Textil-pflegendes Wasch- oder Reinigungsmittel ("2in1"-Wasch- oder Reinigungsmittel) zur Verfügung und er braucht nicht zwei Mittel zu dosieren sowie keinen separaten Spülgang. Da die erfindungsgemäß hergestellten Schmelzkörper parfümhaltig sind, muss nicht auch das Wasch- oder Reinigungsmittel parfümiert werden. Dies führt nicht nur zu geringeren Kosten, sondern ist auch für Verbraucher mit empfindlicher Haut und/oder Allergien vorteilhaft.By introducing the melted bodies produced according to the invention into a detergent or cleaning agent, the consumer has a textile-care detergent or cleaning agent (“2in1” detergent or cleaning agent) available and he does not need to dose two agents or a separate rinse cycle. Since the melting bodies produced according to the invention contain perfume, the washing or cleaning agent does not have to be perfumed as well. Not only does this result in lower costs, but it is also beneficial for consumers with sensitive skin and/or allergies.
Die hierin beschriebenen Schmelzkörper eignen sich insbesondere zum Konditionieren von textilen Flächengebilden und werden dazu zusammen mit einem herkömmlichen Wasch- oder Reinigungsmittel im (Haupt)Waschgang eines herkömmlichen Wasch- und Reinigungsprozesses mit den textilen Flächengebilden in Kontakt gebracht.The melted bodies described herein are particularly suitable for conditioning textile fabrics and are brought into contact with the textile fabrics together with a conventional detergent or cleaning agent in the (main) wash cycle of a conventional washing and cleaning process.
Ist der erfindungsgemäß hergestellte Schmelzkörper Teil eines Wasch- oder Reinigungsmittels, kann ein festes Wasch- oder Reinigungsmittel vorzugsweise mit 1 bis 20 Gew.-%, insbesondere mit 5 bis 15 Gew.-%, der erfindungsgemäßen Schmelzkörper-Zusammensetzung gemischt werden.If the melted body produced according to the invention is part of a detergent or cleaning agent, a solid detergent or cleaning agent can preferably contain 1 to 20% by weight, in particular mixed with 5 to 15% by weight of the melt body composition according to the invention.
Die im Zusammenhang mit den erfindungsgemäßen Verfahren beschriebenen bevorzugten Ausführungsformen sind ebenfalls auf die Schmelzkörper als solche, die diese enthaltenden Wasch- und Reinigungsmittel sowie die hierin beschriebenen Verwendungen übertragbar und umgekehrt.The preferred embodiments described in connection with the methods according to the invention can also be applied to the melted bodies as such, the detergents and cleaning agents containing them and the uses described therein and vice versa.
