Abstract
Description
Chemisch wirksame Enthaarungsmittel, Depilatorien, weisen in der Regel einen Reduktionsmittelgehalt und einen relativ hohen Gehalt eines starken Alkalis auf. Diese Präparate werden auf die zu enthaarenden Hautflächen im allgemeinen überwiegend als Cremes oder Gele oder Schaum appliziert.Chemically active depilatories, depilators, usually have one Reducing agent content and a relatively high content of a strong alkali. These Preparations are generally predominantly applied to the skin to be depilated Applied creams or gels or foam.
Nach einer relativ kurzen Einwirkzeit, ca. 4-8 Minuten, werden die Präparate mit den entsprechenden Haarteilen entfernt.After a relatively short exposure time, approx. 4-8 minutes, the preparations with the appropriate hair pieces removed.
Nach dem Abwischen bzw. Abreiben/Abschaben des Depilatoriums werden die betreffenden Hautpartien gründlich gespült und möglichst mit einer pflegenden, neutralisierenden Creme nachbehandelt.After wiping or rubbing / scraping the depilatory, the affected skin areas thoroughly rinsed and if possible with a nourishing, neutralizing cream aftertreated.
Bei diesen Enthaarungsprozessen kommt es häufig zu Hautirritationen, die sich überwiegend in Rötungen und Hautbrennen bzw. Juckreizen äußern.These hair removal processes often result in skin irritation that can Express mostly in redness and burning skin or itching.
Ferner kann die zu enthaarende Hautfläche unzureichende Enthaarungsresultate zeigen, da die betreffenden Präparate auf Grund der beschriebenen Hautirritationen häufig zu früh entfernt werden.Furthermore, the area of skin to be depilated can show insufficient depilation results, since the preparations in question often increase due to the described skin irritation be removed early.
Um diese Nachteile wenigstens teilweise beheben zu können, wurden in verschiedenen Enthaarungsmitteln hautpflegende Zusätze, wie Proteine, Lanolinderivate, Panthenol, α-Bisabolol u. a., eingearbeitet, die jedoch auf Grund des starken bzw. hohen Alkaligehaltes keine nennenswerte Verbesserung der Hautverträglichkeit erbringen konnten.In order to at least partially remedy these disadvantages, various Depilatory skin care additives such as proteins, lanolin derivatives, panthenol, α-bisabolol u. a., incorporated, but due to the strong or high Alkali content bring no significant improvement in skin tolerance could.
Zudem bewirken diese Komponenten mehr oder weniger eine Abschwächung der reduktiven Wirkung, weshalb diese Präparate ungenügende Enthaarungseffekte erbrachten und/oder, bei längerer Einwirkzeit, dann doch wieder zu Hautunverträglichkeiten führten.In addition, these components more or less weaken the reductive effect, which is why these preparations produced insufficient depilation effects and / or, after prolonged exposure, then again led to skin intolerance.
Ferner wirken sich solche Zusätze zumeist negativ auf die Schaumkraft und Lagerstabilität von Depilatorien aus.Furthermore, such additives mostly have a negative effect on the foaming power and Storage stability from depilators.
Es wurde daher nach neuen Möglichkeiten gesucht, um ein Depilatorium mit folgenden Eigenschaften entwickeln zu können:New opportunities were therefore sought to create a depilatory with the following To be able to develop properties:
- a) Der Wirkstoffgehalt - vor allem der Alkaligehalt - sowie die Einwirkzeit sollten vermindert werden, wodurch die physiologische Verträglichkeit der Präparate gewährleistet werden würde.a) The active substance content - especially the alkali content - and the exposure time should are reduced, thereby reducing the physiological tolerance of the preparations would be guaranteed.
- b) Die Lagerstabilität der Präparate sollte verbessert werden.b) The storage stability of the preparations should be improved.
- c) Durch die Lagerstabilitätsverbesserung sollte eine langfristige Wirkungskonstanz erreicht werden.c) The improvement in storage stability should ensure long-term effectiveness can be achieved.
Überraschenderweise wurde nun gefunden, daß durch den Zusatz von N,N′- Propylenharnstoff die unter a)-c) genannten Eigenschaften realisiert werden können. N,N′-Propylenharnstoffzusätze bewirken bei physiologischer Unbedenklichkeit und ausgezeichneten Enthaarungseffekten eine Verkürzung der Enthaarungszeit und eine mögliche Verminderung des Alkaligehaltes um ca. 30-80%.Surprisingly, it has now been found that the addition of N, N'- Propylene urea the properties mentioned under a) -c) can be realized. N, N'-propylene urea additives cause physiological harmlessness and excellent hair removal effects, a shortening of the hair removal time and a possible reduction of the alkali content by approx. 30-80%.
Auf Grund der dadurch milderen Präparate und kürzeren Einwirkzeit bleiben die enthaarten Hautpartien von Hautirritationen verschont.Because of the milder preparations and shorter exposure time, they remain depilated areas of skin are spared from skin irritation.
Zudem wirkt sich der Propylenharnstoffzusatz sehr günstig auf die Schaumeigenschaften in Aerosol-Enthaarungsmitteln aus, die als Schaum appliziert werden.In addition, the propylene urea additive has a very favorable effect on the foam properties in aerosol depilatories that are applied as foam.
Ferner wird die Lagerstabilität verbessert, es treten keine Separationen auf, wodurch eine homogene Wirkungskonstanz gegeben ist.Furthermore, the storage stability is improved, and no separations occur, as a result homogeneous effectiveness is given.
Nachfolgende Beispiele sollen den Gegenstand der Erfindung verdeutlichen, ohne ihn hierauf zu beschränken:The following examples are intended to illustrate the subject matter of the invention without it to be limited to:
6,30% Cetylstearylalkohol

Das Präparat weist, im Vergleich zu auf dem Markt befindlichen Depilatorien, einen um 75% niedrigeren freien Alkaligehalt auf.Compared to depilators on the market, the preparation detracts one 75% lower free alkali content.
Die entsprechende Wirkung ist jedoch, auf Grund der Carrierkomponente N,N′- Propylenharnstoff, besser als die der lfd. Ware.The corresponding effect is, however, due to the carrier component N, N'- Propylene urea, better than that of current goods.
Der pH-Wert des Mittels liegt bei 12.The pH of the agent is 12.
Auf die zu enthaarenden Körpergegenden wird das Enthaarungsmittel so aufgetragen, meistens mit einem Spatel, daß alle zu entfernenden Haare gleichmäßig davon bedeckt werden. Nach einer Einwirkzeit von 3-6 Minuten wird das Präparat entfernt, die betreffenden Hautgegenden anschließend mit warmem Wasser gespült und ggf. mit einer pH-sauren Lösung neutralisiert. Die Einsatzmenge des Mittels kann - je nach zu enthaarender Körperfläche - stark differieren, kann jedoch im Vorzugsbereich von 5 g-100 g angesiedelt werden.This will affect the parts of the body to be depilated Depilatory applied in such a way, mostly with a spatula, that all hair to be removed is covered evenly will. After an exposure time of 3-6 minutes, it will Preparation removed the affected skin areas then rinsed with warm water and if necessary with a Neutralized pH acid solution. The amount of the agent used can - depending on the depilated body area - strong differ, but can be in the preferred range of 5 g-100 g be settled.
