Description

Production of fragrance-containing enamel body

The present invention relates to a process for producing fused bodies, which comprises preparing 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 thus-obtained melt dispersion with at least one esthetic in a subsequent container and reforming the resulting melt dispersion to obtain solid pastilles. The present invention is further directed to the fins produced by this method, to a detergent or cleaning composition containing them, to the use of such a detergent or cleaner for cleaning textiles or hard surfaces, and to corresponding processes for cleaning textiles or hard Surfaces using such a detergent or cleaning agent.

In the use of detergents and cleaners, the consumer not only aims to wash, cleanse or care for the objects to be treated, but also desires that the treated objects, e.g. Textiles, after the treatment, for example after the wash, smell pleasant. For this reason in particular, most commercially available detergents and cleaners contain fragrances.

Most of the fragrances, however, are volatile. For this reason, when using conventional washing or cleaning agents after use, especially after washing, only a small proportion of the fragrance used remains on the treated object.

As a result, often only a faint scent of the treated object, especially the laundry, goes out, which then already weaker after a short time. Thus, the pleasant feeling of freshness of the treated object disappears after a short time.

Often fragrances are used in the form of perfume pastilles either as an integral part of a washing or cleaning agent, or dosed directly into the washing drum at the beginning of a wash cycle in a separate form. In this way, the consumer can control the fragrance of the laundry to be washed by individual dosage.

Such fragrance pastilles are usually prepared from melt dispersions whose

Main component is a water-soluble or water-dispersible carrier material having a suitable melting temperature. In addition to the likewise containing fragrance components and optionally other excipients, such as detergent substances, such

Melted dispersions and solids are added, for example, to influence the viscosity of the dispersion to be processed. In the prior art manufacturing methods are common in which initially a melt consisting of the carrier material and optionally

Solids and other ingredients is produced and the melt thus obtained directly with the fragrance component and possibly other ingredients such as dyes, is mixed. The finished melt is then transformed. However, such manufacturing processes give enamel bodies, which in terms of their density and the desired

Scope are not optimal.

Thus, there is a need for an improved fused body manufacturing method which allows the density to be adjusted on an application basis.

International patent publication WO 2016/205586 A1 already describes methods and apparatuses which introduce gas into a melt in order to determine the density of the latter

Adjust moldings. The entry of the gas takes place here via a gas line directly into the feed line of the melt, wherein gas and melt are mixed, for example by being introduced together into a mill, for example of the rotor-stator type. As part of this process, the active ingredients used, in particular perfumes and fragrances are exposed to excessive thermal stress.

The object of this application was therefore to provide a manufacturing method for enamel bodies, which allow in a simple manner to adjust the density of these bodies without exposing the active substances and active ingredients used to excessive thermal stress.

This object has been achieved according to the invention by a multi-stage process, in the framework of which a solid and a gas are incorporated into the molten support material used for the production of fused bodies.

In a first aspect, therefore, the present invention is directed to a process for preparing perfume-containing fusible articles, comprising the following steps:

i) preparing a melt dispersion comprising at least one water-soluble or water-dispersible melted carrier material having a melting temperature of> 30 ° C as a continuous phase and at least one solid as a disperse phase in a first container;

ii) mixing the melt dispersion of step i) with at least one esthetic; and iii) transforming the mixture obtained in step ii) to obtain solid fused bodies, characterized in that in step i) in the molten carrier material and / or the melt dispersion, a gas is incorporated.

In another aspect, the present invention is directed to a fuser made in a process as described herein.

In a further aspect, the present invention is also directed to the use of the fused bodies, prepared by a process as described herein, as fabric care agents, preferably fragrances and / or fabric softeners, for perfuming and / or conditioning fabrics.

In yet another aspect, the present invention is further directed to a laundry or cleaning composition comprising a fuser made by a process as described herein.

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. Any feature of one aspect of the invention may be employed in any other aspect of the invention. Further, it is to be understood that the examples contained herein are intended to describe and illustrate the invention, but not to limit it, and in particular that the invention is not limited to these examples.

"Melt" as used herein refers to fusible, water-soluble or water-dispersible solids at standard conditions (20 ° C, 1013 mbar) which are obtainable by solidification and remodeling of the melts described herein.

The fusible bodies can have any shape. The shaping takes place in particular in step iii) of the described method. Preferred are solid, particulate forms, such as substantially spherical, figurative, scale, cuboid, cylindrical, conical, kugelkalotten- or lenticular, hemispherical, disc or needle-shaped enamel bodies. For example, the fusible bodies may have a gummy-like, figurative design. Because of their packaging properties and their performance profile, hemispherical fusible bodies are particularly preferred.

Preferred enamel bodies have in any spatial direction a maximum diameter of between 4 and 15 mm, preferably between 5 and 10 mm. Particularly preferred fusible bodies are characterized by a maximum diameter of 2 to 8 mm, more preferably 4 to 6 mm. On the one hand, such enamel bodies are particularly readily soluble in water and, on the other hand, have a size that is visually appealing to the consumer. 100% hemispheric (hemispherical) particles are characterized by a height to diameter ratio of 0.5. According to the invention, those enamel bodies are also referred to as hemispherical having a height to diameter ratio of 0.25 to 0.49. Particular preference is given to enamel bodies having a height to diameter ratio of 0.35 to 0.45.

The weight of the individual enamel bodies is usually between 2 and 150 mg,

preferably between 5 to 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 support material can be dispersed in water at 20 ° C by known methods.

All percentages are by weight unless otherwise specified. Numeric ranges indicated in the format "from x to y" include the above values. If multiple preferred numeric ranges are specified in this format, it is understood that all ranges resulting from the combination of the various endpoints are also captured.

"At least one" as used herein refers to 1 or more, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9 or more. In particular, this indication refers to the nature of the agent / compound rather than the absolute number of molecules. "At least one perfume" therefore means that at least one type of perfume is detected but also contains two or more different types of perfume can.

The present invention is directed to a fumed body manufacturing process such as fragrance pastilles wherein a melt dispersion is prepared in an uninterrupted process sequence and reshaped in a final step. The method as described herein is characterized in that product changes, i. changed composition of the melt dispersion, for example by using a different fragrance and / or

Color component, without much effort are possible, moreover, the accumulation of unsaleable product quantities can be largely avoided. Another advantage of the method as described herein is that it can be made into the

Melt dispersion incorporated, temperature-sensitive aesthetic one, in comparison to known in the prior art manufacturing process, short residence time at elevated temperatures (corresponding to the melting temperature of the respective support material), whereby after the lozenges made in accordance with the method described herein have an improved color effect and / or improved fragrance when used.

A first subject of the present invention is therefore a process for the production of enamel bodies. According to the present invention, the method comprises the steps described below:

In a first step i), in a first container, a perfume-free melt dispersion comprising at least one water-soluble or water-dispersible carrier material and at least one solid is prepared. The used water-soluble or

water-dispersible molten support material has a melting temperature of> 30 ° C, preferably> 40 ° C and in particular> 50 ° C.

Containers which are suitable for this purpose are generally familiar to the person skilled in the art.

However, the applicability in a method as described herein is that the container permits thorough mixing of the components of the melt dispersion to be produced in step i) and further comprises at least one regulatable aperture through which the components of the melt dispersion to be produced in step i) the container can be introduced, and in addition at least one further adjustable opening through which the melt dispersion prepared in step i) can be discharged from the container. Through these openings, inlet and / or outlet stream can be controlled quantity. The first container may be, for example, a mixing unit. The constituents of the melt are heated to a temperature above the melting point of the support 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 in the first container with the at least one solid.

In some embodiments, the melt dispersion is transferred from the first container into the subsequent container by pressure, so that the melt dispersion is pumped / pressed from the first container into the subsequent container. Such a thing

Pumping out the melt has the advantage that a largely complete, rapid transfer of the melt is ensured from one container to the next, so that as little as possible residual material, which remains as a residue in the respective outlet container, lost. The same applies to the outlet of the melt dispersion prepared in step ii). The transfer of the melt dispersion from the first into the subsequent container or from the following container for forming can also be effected directly by means of suitable mixing units. In order to ensure a process-economic replacement of the carrier material, the melting of the carrier material can be carried out in an additional, the first container upstream container. In various embodiments, the melting of the

Carrier material in principle by heating it to a temperature which is not more than 20 ° C above the melting point of the support material. This also applies if the melting of the carrier material takes place in the first container already described. The melting can be carried out using all customary methods and devices known to the person skilled in the art. According to some embodiments, the thus melted substrate may then be transferred to the first vessel in step i) of the process step a) upstream as described herein to produce the melt dispersion of step i). It is correspondingly desirable that the first container additionally comprises at least one adjustable opening, which allows the introduction of such a melted carrier material. According to some embodiments, the method described herein is characterized

Accordingly, characterized in that the carrier material in a step i) upstream step a) is melted.

In preparing both the melt of step i) and the melt of step ii), the individual flows (all material inlets / outlets as described herein) may optionally be measured by measuring the flow rate of the individual feed streams, i. the melt, the

Perfume stream and possibly other streams are controlled. This also allows, for example, adjust the proportions of the individual components.

The inventive method is preferably characterized in that the melt dispersion prepared in step i) is transferred from the first container directly into the subsequent container.

The production process according to the invention is a sequential one

Process sequence. A process sequence as described herein may be continuous or as a batch process, with a continuous process being preferred. The continuous process management makes it possible to change the amount or chemical nature of the esthetics used during operation, for example to stop the supply of perfume in step ii) and to switch the production to an alternative process product. Due to the late-stage metering of the esthetics in step ii), the residual amounts of such a change by the subsequent melt dispersion only from a part of the

Production plant (the part of the dosing station for the Aesthetic subsequent part of the

Production plant) are rinsed out. The corresponding lead, which contains an undesirable mixture of several esthetics or an incorrect concentration of the desired esthetics, can be discarded or recycled as a blending material (in step i) or ii). As already mentioned, an advantage of the method as described herein is that production changes are made possible without great expense. Due to the sequential process flow, the components to be supplied in the individual process steps, ie carrier material, solid, dye, perfume and possibly other ingredients, can be exchanged largely separately for alternatives, without the entire

Production process must come to a standstill. In addition, in this way the accumulation of large quantities of unsuitable product quantities can be avoided. If, for example, a fragrance and / or dye change take place, the supply of the fragrance and / or dye is first stopped and the melt dispersion prepared in step i) further transferred from the first container in the second container and forwarded from this for forming. As a result, the system is "flushed" with the fragrance and / or dye-free melt, as it were, and fragrance and / or dye residues are removed. The resulting blend can be recycled later in a reuse of the same fragrance and / or dye in the process. Subsequently, another dye and / or fragrance can be supplied, wherein the flow can in turn be discarded or recycled as waste material in the process. There

continuously melt is generated, the change of the fragrance and / or dye takes place, so to speak in the running process and the blending quantities are relatively low.

According to some embodiments, the method described herein is characterized in that waste material which is obtained after step ii) in step i) or ii), preferably in step i) is recycled.

According to the invention, a gas is incorporated into the melt dispersion in step i).

The gas that is introduced may be, for example, air or an inert gas. In various embodiments, it is selected from air, oxygen, nitrogen,

Carbon dioxide, argon or helium, preferably from air, nitrogen or helium, more preferably air. Air is preferred because it is readily available, inexpensive and the interaction with the components of the melt is well understood. Inert gases may be preferred when the melt contains sensitive ingredients, for example, those that are sensitive to the action of oxygen. Melt bodies made by the methods of the invention and containing gas typically have a density that is less than the density of the solid and liquid materials that form the fuser body. The melt body may have gas inclusions and a density of less than about 0.95 g / cm ³ in various embodiments. When substantially all the particles have a density of less than 0.95 g / cm ^3, this means that they float with the use in for example a detergent. This can provide benefits in terms of fragrance release. In various embodiments, the density may also be about 0.9 g / cm ³ or less. Generally, each fuser may be between about 0.5 to about 50 Vol .-% of the particle of gas, preferably between 1 and 20 vol .-%, more preferably between 2 and 15 vol .-%, most preferably between 4 and 12 vol .-%. When the proportion of gas becomes too high, the mechanical properties of the fused bodies suffer. The gas inclusions are preferably as small as possible, typically in the range of 1 to 2000 pm, preferably between 5 and 1000, more preferably between 5 and 200, most preferably between 25 to 50 pm in diameter.

The incorporation of the gas can be incorporated, for example by means of a feed line in the melt dispersion, for example by means of a supply line, for example by means of a

Gas distributor, which the gas flow within the melt, ie below the

Melt surface releases. If the gas is incorporated into the melt by means of a feed line, then the introduction of the gas is preferably carried out at a pressure above 1.1 bar, in particular above 2 bar.

Preferably, however, the gas is incorporated by means of an agitator in the molten carrier material and / or in the melt dispersion.

The agitators are preferably selected from dissolvers, gassing mixers, jet stirrers, propeller stirrers, blade stirrers, preferably dissolvers,

Gassing agitators and jet agitators. The latter have the advantage that they allow easy incorporation of both gases and solids.

A dissolver is a disc stirrer, which is characterized in that a toothed stirrer disc is mounted on a vertical stirrer shaft, which is in the stirred product, i. here the melt is dipped. The disc settles in rotary motion

thereby shear forces, enter the gases or solids and thereby split resulting Festagg lomerate. For a sufficiently high power transmission, the size ratio of

Stirring disc and agitator, as well as the speed and level are observed, with the appropriate parameters for the expert can be selected based on his expertise. As already described above, ideal dispersion is achieved when a torus-like flow pattern is established in the stirred material. The gas to be incorporated is preferably above the melt. For example, when the container is open, the gas may be ambient, or a gas is introduced, which is heavier than air, such as carbon dioxide. Alternatively, a closed container can be used, in which the gas can be introduced so that it is above the material to be stirred. Such an arrangement also allows the incorporation of other gases than air.

Jet mixers or jet mixers (jet mixers / jet mix) are characterized by a fast rotating rotor and a Deflektorrohr surrounding the rotor. All the above agitators can be used in special embodiments for the incorporation of gas, for example in the form of agitators, which feed the gas via a hollow shaft or into which the gas is introduced via a hollow shaft. such

Gassing agitators have a rotatable hollow shaft and at least one arranged on this hollow shaft hollow stirring member, wherein the cavity of the stirring member is in communication with the hollow shaft and the melt towards openings.

Preferably, the molten carrier material and / or the melt dispersion in step i) is stirred in a manner which causes the formation of a trombe in the melt.

The term "T", as used herein, refers to the flow pattern generated at the liquid surface by a stirrer, also referred to as a donut / donut effect. It comes here by the stirring to form a Torusform the Rührguts, ie a 360 ° -Driftdrehung on the spot. The product is stirred by the rotating

Stirring tool, e.g. a dissolver disc, set in motion and conveyed by the centrifugal force to the outside. At the container wall, the material flow is divided and is deflected towards the center. One part runs back to the stirrer at the bottom of the container, the other forms the "donut" on the surface. As a result, parts of the stirring tool are released and become visible, which is referred to herein as a "trumpet that extends into the area of the agitator".

Such a process procedure, for which in particular dissolvers and Leitstrahlrührwerke are suitable, allows the simultaneous homogenization and gas treatment of the melt or melt dispersion.

The stirrers used may consist of any material customary for such stirrers, but in particular of metal or plastic, for example stainless steel or PTFE

Be made (polytetrafluoroethylene). Thankfully, for example, the use of

plastic coated metal / stainless steel stirrers.

In general, agitators with a vertical agitator shaft are preferred.

In summary, a solid and a gas are added to the molten carrier material in step i). The addition of solid and gas makes it possible to adjust the density of the melt dispersion and thus also the density of the resulting melt body. While the density of the melt dispersion for a given material system is directly related to its viscosity, which in turn has an influence on the deformation behavior of the melt and thus on the final spatial form of the fusible bodies, the density of the fusible bodies is Bulk density and thus for the packing volume of the packaging material used for the packaging of the packaging material of importance.

The method makes it possible to adjust the density of the melt before the addition of the esthetics in step ii). In this way, an unnecessarily long processing of the esthetic melt dispersion and thus an unnecessary temperature load on temperature-sensitive aesthetics can be avoided.

In a second step ii), the melt dispersion prepared in step i) is mixed with at least one esthetic. In this case, step ii) is preferably carried out either (1) in a container downstream of the first container or (2), particularly preferably directly in the outlet stream emerging from the first container. The first and subsequent containers are in communication with each other in accordance with the present invention. About this compound, according to the present invention, the produced in the first container

"Subsequent" or "subsequent", as used in this context, means that the container in question is downstream from the first container, i. the volume flow from the first container passes into this subsequent container at a later process time. But it is quite possible that the exiting from the first container volume flow before other, intermediate container passes.

It is also true for the subsequent container that thorough mixing of the components introduced into the container must be ensured. Furthermore, the container comprises at least one adjustable opening, via which the melt dispersion prepared in step i) can be introduced into the container, at least one further adjustable opening, via which the aesthetic (and possibly other components) can be introduced into the container, as well In addition, in addition at least one adjustable opening through which the melt dispersion prepared in step ii) can be discharged from the container. Also, this container may, for example, a suitable mixing unit, such. a static mixer, his.

However, mixing may also be accomplished by continuously mixing the at least one esthetics into the effluent stream exiting the first vessel, i. without the

Necessity of a separate container. In this case, the opening through which the at least one esthetic is introduced into the melt dispersion is preferably adjustable. Although in the following the invention with reference to the mixing in a

subsequent container is described, it is understood that the described

Embodiments also to the above-described alternative of mixing in

Outflow of the first container can be transferred. The mixing volume of the following container also be the volume of the conduit in which the outlet stream is passed from the first container.

In a preferred aspect, the present invention is directed to a method for

Production of fragrance-containing enamel bodies, comprising the following steps:

ii) mixing the melt dispersion of step i) with at least one esthetic, wherein (1) the melt dispersion is transferred to a subsequent container and mixed therein with at least one esthetic, or (2) the at least one esthetics continuously into the outlet stream of the first Container is admixed; and

iii) forming the mixture obtained in step ii) to obtain solid fusible materials, characterized in that in step i) in the molten carrier material and / or the melt dispersion, a gas is incorporated.

Aesthetic, as used herein, refers to an active or adjuvant which is temperature-sensitive at the temperature used to prepare the melt dispersion in step i), ie which is chemically or physically disintegrated at that temperature.

Aesthetic, as used herein, refers more particularly to an active or adjuvant whose use in the fusible bodies is sensory by the consumer. The group of aesthetics includes in particular the fragrances and dyes.

The fragrance is preferably used in liquid form, for example as a perfume oil, solution in a suitable solvent or as a slurry of perfume capsules in a typically hydrous solvent. "Liquid" as used in this context means liquid under the conditions of use, preferably at 20 ° C liquid. However, in some embodiments, the at least one perfume is a substantially "dry", i. largely anhydrous component. According to some

Embodiments, the method described herein is characterized in that the at least one perfume in the form of perfume capsules and / or perfume oils is used.

The dyes are also preferably used in liquid form, for example in the form of an aqueous solution or slurry. In addition to water, the appropriate

Dye formulations also contain organic solvents, in particular polyols. In a third step iii), the melt dispersion obtained in step ii) is converted to obtain solid fused bodies. For example, via the above-mentioned opening, which allows the outlet of the melt dispersion produced in step ii) from the following container, the produced melt is fed to the forming.

The transformation of the melt obtained after step ii) can be carried out by customary shaping processes. Suitable methods of forming are known to those skilled in the art and involve cooling the melt to a temperature which is below the melting temperature of the support material, so that the melt solidifies and / or then obtains its final shape. Examples include pastillation, dripping, flashing, casting followed by

Molding, casting into water-insoluble molds without molding, melt extrusion,

Prilling method and others. According to preferred embodiments, the deformation in step iii) takes place by means of a cooling belt.

With particular preference, the production of the fusible bodies by pastillation takes place. A corresponding preferred method comprises the following steps:

ii) mixing the melt dispersion of step i) with at least one esthetic, wherein (1) the melt dispersion is transferred to a subsequent container and mixed therein with at least one esthetic, or (2) the at least one esthetics continuously into the outlet stream of the first Container is admixed;

In a preferred embodiment, the melt dispersion prepared in step i) is discharged by means of a pipeline from the first container and fed to the drop former. In this case, it is further preferred that the at least one esthetic be continuously introduced into the outflow stream of the first container by means of a further pipeline from a corresponding storage container. For this purpose, in particular, a liquid preparation of the aesthetics, for example in the form of a solution. The temperature of the esthetic or the liquid

Preparation of the esthetics 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 outlet stream, prior to introduction into the outlet stream of the first container. It is further preferred, after the introduction of the esthetic into the melt dispersion, to mix the resulting mixture in the pipeline.

preferably at least 80%, more preferably at least 90% and

in particular over 100% of the length of the drum of the drop former.

The introduced into the feed channel mixture exits from the feed channel preferably located at the bottom of the feed channel bores from the feed channel on a distributor or nozzle bar, which in turn rests against the inside of the rotating, perforated outer drum. The mixture passes through the distributor or nozzle bar and is subsequently discharged from the holes of the rotating outer drum to a steel band located 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.

To further improve the mixing of the melt dispersion and the aesthetics 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 helix arranged rotatably within the feed channel.

As an alternative to the polymeric support materials described above, specific carrier salts may also be used. These specific salts are, in particular, water-containing salts whose partial pressure of water vapor has a certain value Temperature in the range of 30 to 100 ° C corresponds to the hhO partial pressure of the saturated solution of this salt.

The fuser as described herein is prepared from a solution of the carrier material in the water / water of crystallization contained in the composition, and for such a solution, the term "melt" is also used to refer to the state to designate, in which the carrier material dissolves by the elimination of water in its own water of crystallization and thus forms a liquid. The term "melt" as used herein thus refers to the liquid state of the composition which results when the temperature is exceeded at which the support material splits off water of crystallization and then dissolves in the water contained in the composition. The corresponding dispersion containing the herein described (solid) substances dispersed in the melt of the carrier material is thus also the subject of the invention. So if in the

Reference is made below to the solid, particulate composition, and the corresponding melt / melt dispersion from which it is obtainable is always included. Since these do not differ in composition except for the state of matter, the terms are used interchangeably herein.

A preferred support material is characterized in that it is selected from hydrous salts whose water vapor partial pressure at a temperature in the range of 30 to 100 ° C corresponds to the FLO partial pressure of the saturated solution of this salt at the same temperature. This results in the corresponding hydrous salt, also referred to herein as a "hydrate", reaching or exceeding that temperature in its own state

Water of crystallization dissolves and thereby passes from a solid to a liquid state of matter. Preferably, the support materials of the invention exhibit this behavior at a temperature in the range of 40 to 90 ° C, more preferably between 50 and 85 ° C, even more preferably between 55 and 80 ° C.

The water-soluble carrier materials from the group of hydrous salts described above include in particular the sodium acetate trihydrate (Na (CH 3 COO) 3H 2 O), the Glauber salt (Na 2 SO 4 IOH 2 O) and the trisodium phosphate dodecahydrate (Na 3 PO 4 12 H 2 O).

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, concretely at about 58 ° C. The sodium acetate trihydrate can be used directly as such, but it is alternatively possible to use anhydrous sodium acetate in combination with free water, the trihydrate then forming in situ. In such embodiments, the amount of water is in less than or more than stoichiometric amount relative to the amount necessary to convert all of the sodium acetate to sodium acetate trihydrate. used, preferably in an amount of at least 60 wt .-%, preferably at least 70 wt .-%, more preferably at least 80 wt .-%, most preferably 90 wt .-%, 100 wt .-% or more, of the amount theoretically required to convert all of the sodium acetate to sodium acetate trihydrate (Na (CH 3 COO) 3H ₂ O). Particularly preferred is the superstoichiometric use of water. Based on the invention

Compositions means that when (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 equal to the amount stoichiometrically necessary to ensure that at least 60% by weight of the

Total amount of sodium acetate and its hydrates, preferably at least 70 wt .-%, more preferably at least 80 wt .-%, even more preferably at least 90 wt .-%, most preferably at least 100 wt .-%, in the form of sodium acetate trihydrate is present. 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 to the corresponding trihydrate. This means, for example, that a composition containing 50% by weight of anhydrous sodium acetate and no hydrate thereof, at least 19.8% by weight of water (60% of 33% by weight, which would theoretically be necessary to remove all of the sodium acetate into the trihydrate).

All of the embodiments described below can be explicitly combined with both of the aforementioned alternatives.

In various embodiments, the at least one support material from the group of hydrous salts whose water vapor partial pressure at a temperature in the range of 30 to 100 ° C the H ₂ 0 partial pressure of the saturated solution of this salt at the same temperature corresponds, used in an amount in that the resulting fusible 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 fusible body of the carrier material.

The two particularly preferred support materials are polyethylene glycol and sodium acetate.

A first particularly preferred method comprises the following steps:

i) preparing a melt dispersion comprising at least one water-soluble or

water-dispersible molten polyethylene glycol having a melting temperature of> 30 ° C as a continuous phase and at least one solid as a disperse phase in a first container;

ii) mixing the melt dispersion from step i) with at least one perfume, wherein (1) the melt dispersion is transferred to a subsequent container and in this with or at least one fragrance is continuously mixed into the effluent stream of the first container;

A second particularly preferred method comprises the following steps:

i) preparing a melt dispersion comprising sodium acetate trihydrate as a continuous phase and at least one solid as a disperse phase in a first container;

ii) mixing the melt dispersion from step i) with at least one perfume, wherein (1) the melt dispersion is transferred to a subsequent container and mixed therein with at least one perfume, or (2) the at least one perfume continuously into the outlet stream of the first Container is admixed;

As stated, in addition to the at least one support material, the melt dispersion to be produced in step i) comprises at least one solid, for example a filler. To ensure that this at least one solid in the desired particle size is introduced into the first container, it may be advantageous if the first container for this purpose is preceded by at least one screening device, which passes through the at least one solid before entering the first container is introduced. Consequently, according to some embodiments, the method described herein is characterized in that the at least one solid in step i) preceding 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 maize starch, silicic acids, such as pyrogenic silicic acid, silicates, in particular alkali metal silicates, sulphates, in particular alkali metal sulphates, such as

Sodium sulfate, phosphates, especially alkali metal phosphates, such as pentasodium or

Pentakaliumtriphosphat, halides and carbonates, especially alkali metal carbonates, such as sodium carbonate.

The at least one solid may 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 fused bodies. The at least a solid has a melting temperature which is above the melting temperature of the carrier material and the temperature prevailing in the described process so as to provide a melt dispersion.

As also mentioned above, there is another advantage of as herein

in 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 has. Since the fragrance and color component is temperature sensitive, a low residence time at elevated temperatures can improve the fragrance and color quality of said component, thereby providing a superior end product. According to the present method, this advantage is ensured by the fragrance and / or color component comes into contact with the molten material only immediately before the forming.

According to some embodiments, the method described herein is further characterized in that by mixing the subsequent container or conduit in which the melt dispersion prepared in step i) is mixed with the at least one esthetic (and optionally further components) has comparatively small capacity. In this way, in the case of a plant standstill, only relatively small amounts of fragrance are temperature damaged by excessively long residence at elevated temperatures and consequently only small amounts of waste material are formed. In particular, the following container used in step ii), as described herein, has a comparatively low content

Volume volume, if its capacity volume is a maximum of 1500 I, preferably a maximum of 1300 I, especially a maximum of 1000 I, most preferably a maximum of 200 I measures. 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.

Another component of the enamel bodies prepared as described herein is at least one esthetic. Preferred aesthetics are the fragrances and dyes.

A fragrance is an odor-causing chemical substance. In order to stimulate the sense of smell, the chemical substance should be at least partially redistributable in the air, ie the fragrance should be volatile at 25 ° C, at least to a small extent. If the fragrance is now very volatile, the odor intensity then quickly decreases again. At a lower volatility, the smell impression is more sustainable, ie it does not disappear so quickly. In one embodiment, therefore, the perfume has a melting point in the range of -100 ° C to 100 ° C, preferably from -80 ° C to 80 ° C, more preferably from -20 ° C to 50 ° C, especially of 30 ° C to 20 ° C. In a further embodiment, the perfume a boiling point in the range of 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.

Overall, a chemical substance should not exceed a certain molecular weight to act as a fragrance, since too high molecular weight, the required volatility can no longer be ensured. In one embodiment, the fragrance has a molecular weight of 40 to 700 g / mol, more preferably 60 to 400 g / mol.

The smell of a fragrance is perceived by most people as pleasant and often corresponds to the smell of, for example, flowers, fruits, spices, bark, resin, leaves, grasses, mosses and roots. Thus, fragrances can also be used to superimpose unpleasant odors or even to provide a non-smelling substance with a desired odor.
