Description

Verfahren zur Herstellung eines festen Riechstoffkonzentrates Process for the preparation of a solid fragrance concentrate
Die Erfindung betrifft ein Verfahren zur Herstellung eines festen Riechstoffkonzentrates, welches z. B. zur Parfümierung von festen Seifen, von festen Wasch- und Spülmitteln in Pulver-, Granulat-, Chip- oder Tablettenform und von anderen festen haushaltchemischen oder kosmetischen Produkten vorteilhaft einsetzbar ist.The invention relates to a method for producing a solid fragrance concentrate, which, for. B. for perfuming solid soaps, solid detergents and dishwashing detergents in powder, granulate, chip or tablet form and other solid household chemical or cosmetic products.
Eine große Zahl von Riechstoffen oder Riechstoffmischungen sind bei Normaltemperatur flüssige und oftmals leicht flüchtige Substanzen, deren Einbringung in feste haushaltchemische oder kosmetische Produkte wie z. B. feste Seifen bzw. in pulver-, granulat-, chip- oder tablettenförmige Wasch- und Spülmittel Probleme bereitet.A large number of fragrances or fragrance mixtures are liquid at normal temperature and often highly volatile substances, the introduction of which into solid household chemical or cosmetic products such as e.g. B. solid soaps or in powder, granule, chip or tablet detergent and dishwashing problems.
Die bekannten Technologien zur Parfümierung von Festseifen basieren z. B. auf einem intensiven Vermengen der pilierten Rohseife mit flüssigem Riechstoffkonzentrat vor dem Strangpressen und dem Schneiden sowie dem Nachpressen zu einzelnen Seifenstücken. Werden die flüssigen Riechstoffe in größeren Mengen in die pilierte Rohseife eingebracht, wird die Konsistenz der Seife negativ beeinflusst.The known technologies for perfuming solid soaps are based, for. B. on an intensive blending of the piliert raw soap with liquid fragrance concentrate before extrusion and cutting and re-pressing to individual bars of soap. If the liquid fragrances are introduced into the piled raw soap in larger quantities, the consistency of the soap is negatively affected.
Auch ist es nachteilig, dass sich die in dieser Weise in die Festseifen eingebrachten Riechstoffe relativ rasch verflüchtigen, weil der Seifengrundstoff die Riechstoffe nur in geringen Mengen tatsächlich binden kann, so dass nach längerer Lagerung die meisten der in dieser Weise hergestellten Festseifen einen großen Teil des Wohlgeruches eingebüßt haben. Pulverformige feste Wasch- und Spülmittel werden nach dem Stand der Technik vor dem Verpacken bzw. vor ihrer Formung zu Tabletten, Chips usw. mit fein versprühtem flüssigen Riechstoffkonzentrat intensiv vermengt. Bei dem Versprühen der Riechstoffe entstehen durch Verdunsten bereits in der Fertigung hohe Substanzverluste. Außerdem können die oftmals leichtflüchtigen und brennbaren Riechstoffe zusammen mit Luft explosive Gas- Luft-Gemische bilden, wodurch es in den Fertigungsanlagen zu Verpuffungen und Bränden kommen kann.It is also disadvantageous that the fragrances introduced into the solid soaps evaporate relatively quickly, because the base soap can only bind the fragrances in small amounts, so that after prolonged storage most of the solid soaps produced in this way absorb a large part of the Have lost fragrance. Powdery solid detergents and dishwashing agents are intensively mixed with finely sprayed liquid fragrance concentrate before packaging or before they are formed into tablets, chips, etc. When the fragrance is sprayed, evaporation causes high losses of substance during production. In addition, the often volatile and flammable fragrances together with air can form explosive gas-air mixtures, which can lead to deflagrations and fires in the manufacturing plants.
Um diese Nachteile zu vermeiden, wurde bereits versucht, feste Riechstoffkonzentrate herzustellen, indem z. B. pulverformige gefällte Kieselsäure oder andere pulverformige Trägermaterialien, die eine große innere Oberfläche aufweisen, mit den flüssigen Riechstoffen bzw. Riechstoffmischungen benetzt wurden, wodurch der flüssige Riechstoff bzw. die flüssigen Riechstoffmischungen von den pulverförmigen Materialien adsorbiert und an die inneren Oberflächen dieser Materialien gebunden wurden. Diese pulverförmigen Trägermaterialien sind zwar in der Lage, relativ große Anteile von flüssigen Riechstoffen aufzunehmen und zu binden, da sie jedoch im Wasser schlecht löslich sind, stellen sie vor allem für feste Seifen sowie für Wasch- und Spülmittel unerwünschte Ballaststoffe dar, die zu schädlichen Ablagerungen auf dem Wasch- und Spülgut sowie in den Geräten und Leitungen führen, und sie sind deshalb als Trägermaterialien zur Einbringung von Riechstoffen vor allem in feste Seifen sowie in feste Wasch- und Spülmittel ungeeignet. Außerdem ist das Haftvermögen dieser bekannten Stoffe auf Grund ihrer großen inneren Oberflächen zum Teil so groß, dass sich die Riechstoffe beim Wasch- oder Spülvorgang nicht lösen und entfalten können und somit ungenutzt fortgespült werden.In order to avoid these disadvantages, attempts have already been made to produce solid fragrance concentrates by, for. B. powdered precipitated silica or other powdered carrier materials, which have a large inner surface, were wetted with the liquid fragrance or fragrance mixtures, whereby the liquid fragrance or the liquid fragrance mixtures were adsorbed by the powdery materials and bound to the inner surfaces of these materials , These powdered carrier materials are able to absorb and bind relatively large amounts of liquid fragrances, but because they are poorly soluble in water, they represent unwanted fiber, especially for solid soaps as well as detergents and detergents, which lead to harmful deposits lead on the items to be washed and washed, as well as in the appliances and lines, and are therefore unsuitable as carrier materials for introducing fragrances, especially in solid soaps and in solid detergents and dishwashing detergents. In addition, due to their large inner surfaces, the adhesiveness of these known substances is in part so great that the odoriferous substances cannot dissolve and develop during the washing or rinsing process and are therefore washed away unused.
Es ist deshalb Aufgabe der Erfindung, ein Verfahren zur Herstellung eines festen Riechstoffkonzentrates durch Aufnahme eines flüssigen Riechstoffes in einem festen Stoff oder einem Feststoffgemisch zu entwickeln, bei welchem der feste Stoff oder das Feststoffgemisch in der Lage ist, den flüssigen Riechstoff bzw. die flüssigen Riechstoffe in größeren Mengen aufzunehmen, ohne diese(n) in zu hohem Maße zu binden, und ohne dass der feste Stoff oder das Feststoffgemisch, einen unlöslichen Ballaststoff darstellt. Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausfüthrungsformen der Erfindung bilden die Merkmale der Unteransprüche 2 bis 10.It is therefore an object of the invention to develop a process for the production of a solid fragrance concentrate by taking up a liquid fragrance in a solid substance or a mixture of solids, in which the solid substance or the mixture of solids is capable of the liquid fragrance or the liquid fragrances in larger quantities, without binding them too much, and without the solid or mixture of solids constituting an insoluble fiber. The object is achieved by the characterizing features of patent claim 1. Advantageous embodiments of the invention form the features of subclaims 2 to 10.
Die Erfindung soll im Weiteren anhand von bevorzugten Ausführungsbeispielen näher erläutert werden.The invention is to be explained in more detail below on the basis of preferred exemplary embodiments.
Die meisten Riechstoffe befinden sich bei Normaltemperatur von 20 °C im flüssigen Aggregatzustand. Für den Verbraucher anwendungsbereite Riechstoffe sind in den meisten Fällen Riechstoffgemische aus bis zu 40, in Einzelfällen sogar noch mehr einzelnen Riechstoffkomponenten. Um diese bei Normaltemperatur flüssigen Riechstoffe oder Riechstoffgemische in relativ hohen Konzentrationen und in bequemer Weise in feste Seifen, in Pulver- oder in anderen festen Formen vorliegende Wasch- und Spülmittel oder andere feste haushaltchemische oder kosmetische Produkte einbringen zu können, ohne dass die Qualität der Produkte merklich beeinträchtigt wird oder dass im Fertigungsablauf Nachteile oder Gefahren eintreten, werden die flüssigen Riechstoffe erfmdungsgemäß in bei Normaltemperatur festen Tensiden oder Kotensiden gelöst. Dies geschieht durch Erwärmung von geeigneten festen Tensiden oder Kotensiden bzw. von Tensid- bzw. Kotensidgemischen auf Temperaturen, die nur geringfügig oberhalb der Erstarrungspunkte dieser Stoffe liegen, darauf folgendes Einbringen der flüssigen Riechstoffe oder Riechstoffgemische in die verflüssigten Tenside oder Kotenside bzw. Tensid-Kotensid-Gemische und nachfolgendes Abkühlen, wobei sich die Tenside oder Kotenside bzw. das Tensid-Kotensid-Gemisch mit dem darin gelösten mindestens einem Riechstoff unterhalb einer bestimmten Erstarrungstemperatur, die oberhalb der Normaltemperatur von 20 °C liegt, zu einem erfindungsgemäßen festen Riechstoffkonzentrat verfestigt.Most fragrances are in the liquid state at a normal temperature of 20 ° C. Fragrances ready for use by the consumer are in most cases mixtures of up to 40, in some cases even more, individual fragrance components. In order to be able to introduce these fragrances or fragrance mixtures, which are liquid at normal temperature, in relatively high concentrations and conveniently into solid soaps, powder or other solid detergents and dishwashing detergents or other solid household chemical or cosmetic products, without affecting the quality of the products is noticeably impaired or that disadvantages or dangers occur in the production process, the liquid fragrances are dissolved according to the invention in surfactants or cosurfactants which are solid at normal temperature. This is done by heating suitable solid surfactants or cosurfactants or surfactant or cosurfactant mixtures to temperatures which are only slightly above the solidification points of these substances, then introducing the liquid fragrance or fragrance mixtures into the liquefied surfactants or cosurfactants or surfactant-cosurfactant Mixtures and subsequent cooling, wherein the surfactants or surfactants or the surfactant-surfactant mixture with the at least one fragrance dissolved therein solidifies below a certain solidification temperature, which is above the normal temperature of 20 ° C., to give a solid fragrance concentrate according to the invention.
Mittels des erfindungsgemäßen Verfahrens lassen sich in den Tensiden oder Kotensiden bzw. in den Tensid-Kotensid-Gemischen bis zu 60 Gew.-% flüssige Riechstoffe lösen und zu einem erfϊndungsgemäßen festen Riechstoffkonzentrat verfestigen.Using the method according to the invention, up to 60% by weight of liquid fragrances can be dissolved in the surfactants or cosurfactants or in the surfactant-cosurfactant mixtures and solidified to form a solid fragrance concentrate according to the invention.
In einem speziellen Anwendungsfall wurden in 60 Gew.-% eines verflüssigten Fettalkohols C22 der auf eine Temperatur von wenigen Graden oberhalb des Erstarrungspunktes von 70 °C erhitzt wurde, 40 Gew.-% eines flüssigen Riechstoffgemisches gelöst. Die Fettalkohol-Riechstoff-Lösung erstarrte beim Abkülilen bei einer Temperatur unterhalb 54 °C zu dem erfindungsgemäßen festen Riechstoffkonzentrat.In a special application, 60% by weight of a liquefied fatty alcohol C22 was heated to a temperature of a few degrees above the solidification point of Was heated to 70 ° C, 40 wt .-% of a liquid fragrance mixture dissolved. The fatty alcohol fragrance solution solidified on cooling at a temperature below 54 ° C. to give the solid fragrance concentrate according to the invention.
In einem weiteren Anwendungsfall wurden in einem verflüssigten Gemisch aus 30 Gew.-% Fettalkohol C22 und 30 Gew.-% Fettsäure (Stearin), das einen Erstaπrjjngspunkt von 68 °C aufwies, 40 Gew.-% eines flüssigen Riechstoffgemisches gelöst. Die Fettalkohol-Fettsäure- Riechstoff-Lösung erstarrte beim Abkühlen bei einer Temperatur von unterhalb 47 °C zu dem erfindungsgemäßen festen Riechstoffkonzentrat.In a further application, 40% by weight of a liquid fragrance mixture were dissolved in a liquefied mixture of 30% by weight of fatty alcohol C22 and 30% by weight of fatty acid (stearin), which had an initial point of 68 ° C. The fatty alcohol-fatty acid-fragrance solution solidified on cooling at a temperature below 47 ° C. to give the solid fragrance concentrate according to the invention.
In noch einem weiteren Anwendungsfall wurden in einem verflüssigten Gemisch aus 30 Gew.-% Fettalkohol C22 und 30 Gew.-% Polyethylenglykol, das einen Erstarrungspunkt von 60 °C aufwies, bei einer Temperatur von 80 °C 40 Gew.-% Riechstoffe gelöst. Die Fettalkohol-Polyethylenglykol-Riechstoff-Lösung erstarrte beim Abkühlen bei einer Temperatur von unterhalb 54 °C zu dem erfindungsgemäßen festen Riechstoffkonzentrat.In yet another application, 40% by weight of fragrance substances were dissolved in a liquefied mixture of 30% by weight of fatty alcohol C22 and 30% by weight of polyethylene glycol, which had a solidification point of 60 ° C., at a temperature of 80 ° C. The fatty alcohol-polyethylene glycol fragrance solution solidified on cooling at a temperature below 54 ° C. to give the solid fragrance concentrate according to the invention.
Die in der vorstehenden Weise gewonnenen festen Riechstoffkonzentrate können mittels bekannter Verfahren in pastillierter oder granulierter Form hergestellt werden, und sie lassen sich in dieser Form bei der Herstellung fester Seifen, pulver-, granulat- oder tabletten- förmiger Wasch- und Spülmittel bzw. anderer fester haushaltchemischer oder kosmetischer Produkte problemlos zugeben und präzise dosieren.The solid fragrance concentrates obtained in the above manner can be produced in known form in pelletized or granulated form, and they can be used in this form in the production of solid soaps, powder, granule or tablet detergents and dishwashing detergents or other solid ones Add household chemical or cosmetic products easily and dose precisely.
