Abstract

The invention relates to a method for the production of a solid fragrance concentrate, by absorption of a liquid fragrance or fragrance mixture in a solid or solid mixture, using one or several surfactants and/or co-surfactants, solid at normal temperatures as solid or solid mixture, whereby the liquid fragrance or fragrance mixture is dissolved in the above at a temperature above the solidification temperature of the solid or solid mixture and the solution subsequently solidified by cooling. The solid or solid mixture comprises fatty alcohol(s) or a mixture of fatty alcohol(s) and fatty acid(s) and/or fatty alcohol ethoxylate and/or polyethylene glycol.

Description

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 process for the preparation of a solid fragrance concentrate, which z. B. for perfuming solid soaps, solid washing and rinsing agents in powder, granule, chip or tablet form and other solid household chemical or cosmetic products is advantageously used.

Eine große Zahl von Riechstoffen oder Riechstoffinischungen 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 volatile substances whose introduction into solid household chemical or cosmetic products such. As solid soaps or in powder, granular, chip or tablet detergent and detergent 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 of solid soaps based z. B. on an intensive blending the piled raw soap with liquid fragrance concentrate before extruding and cutting and repressing to individual soap bars. If the liquid fragrances are introduced in large quantities into the pilfered raw soap, the consistency of the soap is adversely 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.It is also disadvantageous that the fragrances introduced into the solid soaps volatilize relatively quickly, because the soap base can actually bind the fragrances only in small amounts, so that after prolonged storage most of the solid soaps produced in this way make up a large part of the solids Have lost their fragrance.

Pulverförmige feste Wasch- und Spülmittel wurden 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.Powdered solid washing and rinsing agents were intensively mixed according to the prior art prior to packaging or before their formation into tablets, chips, etc. with finely sprayed liquid fragrance concentrate. When the fragrances are sprayed, high losses of substance occur during evaporation due to evaporation. In addition, the often volatile and combustible fragrances together with air form explosive gas-air mixtures, which can lead to deflagrations and fires in the production plants.

Um diese Nachteile zu vermeiden, wurde bereits versucht, feste Riechstoffkonzentrate herzustellen, indem z. B. pulverförmige gefällte Kieselsäure oder andere pulverförmige 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.To avoid these disadvantages, attempts have been made to produce solid fragrance concentrates by z. As powdered precipitated silica or other powdery carrier materials having a large inner surface were wetted with the liquid fragrances or fragrance mixtures, whereby the liquid fragrance or the liquid fragrance mixtures were adsorbed by the powdery materials and bonded to the inner surfaces of these materials , Although these powdery carrier materials are able to absorb relatively large amounts of liquid fragrances and bind, but since they are sparingly soluble in water, they represent unwanted dietary fiber, especially for solid soaps and for washing and rinsing, which leads to harmful deposits on the washing and ware as well as in the equipment and lines, and they are therefore unsuitable as carrier materials for the introduction of fragrances, especially in solid soaps and solid detergents and detergents. In addition, the adhesion of these known substances due to their large inner surfaces is sometimes so great that the fragrances can not dissolve and unfold during washing or rinsing and thus be washed away unused.

Aus der DE 19735783 A1 ist ferner ein hochdosierter Duftstoff-Formkörper mit einem Gehalt von 20 bis 50 Gew.-% Duftstoff und der Restmenge, d. h. mindestens 50 % Trägermaterial aus Fettsäure und fettsaurem Salz bekannt. Von diesem Anteil des Trägermaterials von mindestens 50 Gew.-% an der Gesamtmasse des Duftstoff-Formkörpers können bis zu 50 Gew.-% durch übliche Inhaltsstoffe von Wasch- und Reinigungsmitteln, wie z. B. Enzyme, Bleichmittel, Schauminhibitoren, Farbstoffe, pH-Stellmittel usw. ersetzt werden, wobei diese Inhaltsstoffe nur teilweise Trägermaterialeigenschaften besitzen.From DE 19735783 A1 is also a high-dose perfume molding with a content of 20 to 50 wt .-% perfume and the balance, d. H. at least 50% carrier material of fatty acid and fatty acid salt known. Of this proportion of the support material of at least 50 wt .-% of the total mass of the perfume molding can be up to 50 wt .-% by conventional ingredients of detergents and cleaners, such as. As enzymes, bleaches, foam inhibitors, dyes, pH adjusters, etc. are replaced, these ingredients have only partial carrier material properties.

Letztgenannte Duftstoff-Formkörper sind auf eine Duftstoffaufnahme von 50 Gew.-% beschränkt. Außerdem sind die als Trägermaterialien verwendeten Fettsäuren und fettsauren Salze nur bedingt biologisch abbaubar.The latter perfume moldings are limited to a perfume uptake of 50 wt .-%. In addition, the fatty acids and fatty acid salts used as support materials are only partially biodegradable.

Aus dem französischen Patent FR-A-2123824 ist eine feste Duftstoffzusammensetzung bekannt, die ein Seifengel, ein organisches Lösungsmittel und einen Duftstoff beinhaltet. Ein solcher Duftstoff ist von gelartiger Konsistenz und nicht wirklich fest.French Patent FR-A-2123824 discloses a solid fragrance composition comprising a soap gel, an organic solvent and a fragrance. Such a fragrance is gelatinous and not really firm.

In ähnlicher Weise handelt es sich bei dem US-Patent 3945950 offenbarten festen Duftstoff ebenfalls um ein gelartiges Produkt, das aus einem Gelbildner, einem Ether und einem Duftstoff besteht, wobei der Anteil des Ethers größer ist als der des Duftstoffes. Die gelartige Konsistenz macht diese Art von festen Duftstoffen des Standes der Technik zum Einbringen z. B. in pulverförmige feste Wasch- und Spülmittel ungeeignet.Similarly, the solid fragrance disclosed in US Patent 3,945,950 is also a gelatinous product consisting of a gelling agent, an ether, and a fragrance wherein the proportion of the ether is greater than that of the fragrance. The gel-like consistency makes this type of solid fragrances of the prior art for introducing z. B. in powdery solid detergents and detergents unsuitable.

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 auch 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.It is therefore an object of the invention to develop a process for the preparation of a solid fragrance concentrate by incorporating a liquid fragrance in a solid or a solid mixture in which the solid or the solid mixture is capable of the liquid fragrance or the liquid fragrances also to take up in large quantities, without binding these too high, and without the solid substance or the solid mixture, an insoluble fiber.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung bilden die Merkmale der Unteransprüche 2 bis 8.The object is solved by the characterizing features of claim 1. Advantageous embodiments of the invention form the features of the subclaims 2 to 8.

Die Erfindung soll im Weiteren anhand von bevorzugten Ausführungsbeispielen näher erläutert werden.The invention will be explained in more detail below with reference to preferred 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 erfindungsgemäß in bei Normaltemperatur festen Tensiden oder Kotensiden gelöst, die Fettalkohol(e) oder ein Gemisch von Fettalkohol(en) mit Fettsäure(n) und/oder Fettalkoholethoxylat und/oder Polyethylenglykol umfassen. Dies geschieht durch Erwärmung des Fettalkohols bzw. der Fettalkohole oder des genannten Stoffgemisches 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 verfestigen.Most odoriferous substances are in the liquid state at a normal temperature of 20 ° C. For the consumer, ready-to-use fragrances are in most cases perfume mixtures of up to 40, in some cases even more individual fragrance components. In order to introduce these at normal temperature liquid fragrances or fragrance mixtures in relatively high concentrations and conveniently present in solid soaps, in powder or other solid forms detergents and dishwashing or other solid household chemical or cosmetic products, without compromising the quality of the products According to the invention, the liquid fragrances are dissolved in normal surfactants or surfactants which contain fatty alcohol (s) or a mixture of fatty alcohol (s) with fatty acid (s) and / or fatty alcohol ethoxylate and / or or polyethylene glycol. This is done by heating the fatty alcohol or fatty alcohols or the said mixture to temperatures which are only slightly above the solidification points of these substances, then introducing the liquid fragrances or fragrance mixtures in the liquefied surfactants or fumed or surfactant-cosurfactant mixtures and the following Cooling, wherein the surfactants or cosurfactants or the surfactant-cosurfactant mixture having dissolved therein at least one fragrance below solidify a certain solidification temperature, which is above the normal temperature of 20 ° C, to a solid perfume concentrate according to the invention.

Mittels des erfindungsgemäßen Verfahrens lassen sich in den Tensiden oder Kotensiden bzw. den Tensid-Kotensid-Gemischen bis zu 60 Gew.-% flüssige Riechstoffe lösen und zu einem erfindungsgemäßen festen Riechstoffkonzentrat verfestigen.By means of the process according to the invention, up to 60% by weight of liquid fragrances can be dissolved in the surfactants or cosurfactants or the surfactant / cosurfactant mixtures and solidified to give a solid perfume 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 Abkühlen bei einer Temperatur unterhalb 54 °C zu dem erfindungsgemäßen festen Riechstofflconzentrat.In a special application, 40% by weight of a liquid fragrance mixture was dissolved in 60% by weight of a liquefied fatty alcohol C22 which had been heated to a temperature of a few degrees above the solidification point of 70 ° C. The fatty alcohol-fragrance solution solidified on cooling at a temperature below 54 ° C to 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 Erstarrungspunkt 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 another application, 40% by weight of a liquid fragrance mixture was dissolved in a liquefied mixture of 30% by weight of fatty alcohol C22 and 30% by weight of fatty acid (stearin), which had a freezing point of 68 ° C. The fatty alcohol-fatty acid fragrance solution solidified on cooling at a temperature of below 47 ° C to the solid perfume 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, 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., 40% by weight of fragrances were dissolved at a temperature of 80 ° C. The fatty alcohol-polyethylene glycol fragrance solution solidified on cooling at a temperature of below 54 ° C to the solid perfume 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 tablettenförmiger Wasch- und Spülmittel bzw. anderer fester haushaltchemischer oder kosmetischer Produkte problemlos zugeben und präzise dosieren.The solid perfume concentrates obtained in the above manner can be prepared by known methods in pastillierter or granulated form, and they can be in this form in the production of solid soaps, powder, granular or tablet detergent and rinse or other solid household chemical or easily admit and precisely dose cosmetic products.
