Abstract

Immobilization of perfumes or perfume mixtures with SiO2.

Description

Die Erfindung betrifft die Immobilisierung von Duftstoffen oder Dufstoffmischungen mit Siliciumdioxid und die Verwendung der so hergestellten Parfumgele.The invention relates to the immobilization of fragrances or fragrance mixtures with silicon dioxide and the use of the perfume gels so produced.

Es bestand die Aufgabe Duftstoffe und/oder komplexe Parfumkompositionen zu immobilisieren um diese bei Bedarf durch Erwärmung freizusetzen (thermische Freisetzung). Hierfür werden Materialien benötigt, die auch bei höheren Tempera­ turen (bis 300°C) keine chemischen Zersetzungen oder Reaktionen mit Parfumölen und Trägermaterialien zeigten.The task was to create fragrances and / or complex perfume compositions immobilize to release them by heating if necessary (thermal Release). For this, materials are required, even at higher temperatures (up to 300 ° C) no chemical decomposition or reactions with perfume oils and showed substrates.

Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Immobilsierung von Duftstoffen oder Dufstoffmischungen mit Siliciumdioxid.The present invention relates to a method for immobilizing Fragrances or fragrance mixtures with silicon dioxide.

Ein weiterer Gegenstand der vorliegenden Erfindung ist die Verwendung der durch Immobilsierung von Duftstoffen oder Dufstoffmischungen hergestellten Parfümgele zur thermischen Freisetzung des Duftstoffes oder der Duftstoffe.Another object of the present invention is the use of the Immobilization of perfumes or perfume mixtures produced perfume gels for the thermal release of the fragrance or fragrances.

Aus der Pharmazie sind hochdisperse pyrogene Siliciumdioxide, die sogenannten Aerosile® (Markenname der Firma Degussa), bekannt. Diese Siliciumdioxide sind unbrennbar, nicht toxisch, geruchlos und beispielsweise in Lebensmittelbedarfs­ gegenständen, Spielwaren, Kosmetika, Pharmazeutika zugelassen. Der Schmelz­ bereich liegt bei ca. 1700°C.Pharmaceuticals are highly dispersed fumed silicas, the so-called Aerosile® (brand name of Degussa), known. These are silica non-flammable, non-toxic, odorless and for example in food needs objects, toys, cosmetics, pharmaceuticals approved. The enamel range is approx. 1700 ° C.

Unsere Versuche führten zu dem Ergebnis, dass z. B. das Aerosil V 200 der Firma Degussa ein sehr gutes "Gelierungsmittel" für fast alle Parfumkompositionen ist.Our experiments led to the result that e.g. B. the company's Aerosil V 200 Degussa is a very good "gelling agent" for almost all perfume compositions.

Ein ausreichender Gelierungseffekt wird mit einem Anteil an Aerosil V 200 von 7 bis 15 Gew.-% erreicht. Zur Herstellung wird das Aerosil vorgelegt und der Duftstoff und/oder die komplexe Parfumkomposition hinzugegeben. Anschließend wird die Mischung durch Rühren homogenisiert. A sufficient gelling effect is achieved with a proportion of Aerosil V 200 from 7 to 15 wt .-% reached. The aerosil and the fragrance are presented for manufacture and / or the complex perfume composition is added. Then the Mix homogenized by stirring.  

Mit dieser Entwicklung steht ein Parfumgel zur Verfügung, in dem der Parfumöl­ anteil 85 bis 93% beträgt. Die Freisetzung der Duftstoffe kann kontinuierlich (auch bei Raumtemperatur) erfolgen, da eine "Verkapselung" des Parfumöls nicht erzielt wird.With this development, a perfume gel is available in which the perfume oil share is 85 to 93%. The release of the fragrances can be continuous (too at room temperature) because the perfume oil is not "encapsulated" becomes.

Eine Temperaturerhöhung beschleunigt die Freisetzung des Parfumöls ähnlich wie bei einem flüssig vorliegenden Produkt. Als wichtiger zusätzlicher Effekt ist hervorzuheben, dass sich das Gel auch bei erhöhten Temperaturen nicht verflüssigt, so das ein Ver- oder Auslaufen von Parfumgel-Dosierungen nicht erfolgt. Nach vollständiger Verdampfung des Duftstoffes und/oder der komplexen Parfum­ komposition bleibt als Rückstand das Siliciumdioxid als staubähnlicher Feststoff zurück.An increase in temperature accelerates the release of the perfume oil in a similar way with a liquid product. As an important additional effect to emphasize that the gel does not liquefy even at elevated temperatures, so that perfume gel doses do not run or run out. To complete evaporation of the fragrance and / or the complex perfume The composition remains the silicon dioxide as a dust-like solid back.
