Transparentes kosmetisches Gel Transparent cosmetic gel
Die vorliegende Erfindung betrifft durch ein transparentes kosmetisches Gel mit einer Viskosität von mindestens 15000 mPas, enthaltend a) Xanthangummi (INCI: Xanthan gum) und/oder iota-Carrageenan (INCI: Carrageenan) und b) Carboxymethylcellulose (INCI: Cellulose gum), wobei die Zubereitung frei ist von Polyacrylaten und Carbomeren. The present invention relates to a transparent cosmetic gel with a viscosity of at least 15,000 mPas, containing a) xanthan gum (INCI: xanthan gum) and / or iota-carrageenan (INCI: carrageenan) and b) carboxymethylcellulose (INCI: cellulose gum), wherein the preparation is free from polyacrylates and carbomers.
Der Wunsch, schön und attraktiv auszusehen, ist von Natur aus im Menschen verwurzelt. Auch wenn das Schönheitsideal im Laufe der Zeit Wandlungen erfahren hat, so ist das Streben nach einem makellosen Äußeren, immer das Ziel der Menschen gewesen. Einen wesentlichen Anteil an einem schönen und attraktiven Äußeren hat dabei der Zustand und das Aussehen der Haut. The desire to look beautiful and attractive is inherently rooted in people. Even if the ideal of beauty has changed in the course of time, striving for a flawless appearance has always been the goal of people. The condition and appearance of the skin play a key role in a beautiful and attractive appearance.
Damit die Haut ihre biologischen Funktionen im vollen Umfang erfüllen kann, bedarf sie der regelmäßigen Reinigung und Pflege. Hautpflegeprodukte, in der Regel Cremes, Salben oder Lotionen, dienen meist der Befeuchtung und Rückfettung der Haut. Häufig sind ihnen Wirkstoffe zugesetzt, welche die Haut regenerieren und beispielsweise ihre vorzeitige Alterung (z.B. das Entstehen von Fältchen, Falten) verhindern und vermindern sollen. In order for the skin to be able to fully fulfill its biological functions, it needs regular cleaning and care. Skin care products, usually creams, ointments or lotions, are mostly used to moisturize and re-oil the skin. Often, active ingredients are added to them that regenerate the skin and, for example, prevent and reduce its premature aging (e.g. the appearance of fine lines and wrinkles).
Neben der Reinigung und Pflege der Haut haben Kosmetika auch eine ästhetische Aufgabe. Sie sollen das äußere Erscheinungsbild des Anwenders entsprechend den jeweiligen kulturellen Vorstellungen „verbessern“. Kosmetika erfüllen damit eine psychologisch-soziale Funktion, da sie die (optische) Attraktivität der Anwender erhöhen. In diesen Bereich fällt vor allen Dingen die „dekorative“ Kosmetik, die mit Hilfe von auf die Haut aufgetragenen Farbstoffen das Erscheinungsbild der Anwender verändert. Indirekt haben aber auch Reinigungs- und Pflegeprodukte einen positiven Einfluss, da eine saubere, gesunde Haut dem Schönheitsideal der Menschen entspricht. l
In jüngerer Zeit gibt es einen verstärkten Trend hin zu „natürlichen“ Kosmetika, deren Inhaltsstoffe möglichst nicht mehr aus Erdölprodukten stammen oder chemisch synthetisiert sein sollen. Dabei stellt die Suche nach alternativen Inhaltsstoffen, welche diese Kriterien erfüllen, die Produktentwickler vor besondere Herausforderungen. Denn der Austausch der bekannten Inhaltstoffe wie Mineralöle, Silikonöle, Polyacrylate wird praktisch immer mit Nachteilen im Hinblick auf die Anwendung der Produkte erkauft. Die Zubereitungen werden sensorisch unattraktiv, was sich beispielsweise beim Verteilen der Zubereitung auf der Haut und dem mangelnden Einzugsvermögen unangenehm bemerkbar macht. So führt unter anderem der Austausch von Mineralölen, Silikonölen und Acrylat-Polymeren wie Polyacrylaten, Carbomeren, Acrylates/C 10-30 Alkylacrylate Crosspolymer zu einem verstärkten „Weißein“ beim Verreiben der Zubereitung auf der Haut. In addition to cleaning and caring for the skin, cosmetics also have an aesthetic function. They should "improve" the external appearance of the user according to the respective cultural ideas. Cosmetics thus fulfill a psychological and social function, as they increase the (visual) attractiveness of the user. This area primarily includes "decorative" cosmetics, which change the appearance of the user with the help of dyes applied to the skin. But cleaning and care products also have a positive influence indirectly, since clean, healthy skin corresponds to people's ideal of beauty. l In recent times there has been an increased trend towards “natural” cosmetics, the ingredients of which no longer come from petroleum products or should be chemically synthesized. The search for alternative ingredients that meet these criteria poses particular challenges for product developers. Because the exchange of the known ingredients such as mineral oils, silicone oils, polyacrylates is practically always paid for with disadvantages with regard to the application of the products. The preparations become unattractive from a sensory point of view, which becomes unpleasantly noticeable, for example, when the preparation is distributed on the skin and the lack of absorption capacity. Among other things, the exchange of mineral oils, silicone oils and acrylate polymers such as polyacrylates, carbomers, acrylates / C 10-30 alkyl acrylate cross-polymer leads to increased "whiteness" when the preparation is rubbed on the skin.
Eine besondere Herausforderung stellt dabei vor allem die Entwicklung transparenter, wässriger Gele dar, denn diese werden üblicherweise mit Polymeren auf der Basis von Acrylat-Polymeren verdickt. Nach dem Stande der Technik lässt sich mit keiner anderen Verbindungsklasse transparenter verdicken. A particular challenge is the development of transparent, aqueous gels, because these are usually thickened with polymers based on acrylate polymers. According to the state of the art, no other class of compounds can be used to thicken more transparently.
Bei den transpatenten wässrigen Gelen, die im Rahmen der vorliegenden Offenbarung der Einfachheit halber als transparente Gele bezeichnet werden, tritt neben der Frage, wie man auf „natürliche“ Weise transparent verdicken (= die Viskosität erhöhen) kann auch noch das Problem auf, dass die mikrobielle Stabilität der Produkte gewährleistet werden muss, damit das Produkt nicht verkeimt oder sich mikrobiell zersetzt. Nach dem Stande der Technik werden bei wässrigen Gelen üblicherweise Parabene und andere synthetische, antimikrobiell wirksame Substanzen eingesetzt, da „natürliche“ Konservierungsmethoden, wie das „ansäuern“ (d.h. eine pH-Wert Erniedrigung) beim Einsatz von Acrylat-Polymeren ausscheidet. Werden Polyacrylate unter Bildung der Polyacrylssäure „angesäuert“ bricht das die Viskosität erhöhende Gelnetzwerk zusammen. In the case of the transparent aqueous gels, which are referred to as transparent gels for the sake of simplicity in the context of the present disclosure, in addition to the question of how to thicken transparently in a “natural” way (= increase the viscosity), the problem can also arise that the microbial stability of the products must be guaranteed so that the product does not germinate or decompose microbially. According to the state of the art, parabens and other synthetic, antimicrobial substances are usually used in aqueous gels, since "natural" preservation methods such as "acidification" (i.e. lowering the pH value) are not necessary when using acrylate polymers. If polyacrylates are "acidified" with the formation of polyacrylic acid, the gel network that increases the viscosity breaks down.
Es war daher die Aufgabe der vorliegenden Erfindung, ein transparentes, wässriges kosmetisches Gel zu entwickeln, das auf der Basis natürlicher Rohstoffe verdickt und konserviert werden kann. Auf den Einsatz von Acrylat-Polymeren, Parabenen, Methylisothiazolinon, Chlormethyl- isothiazolinon sowie DMDM-Hydantoin und anderen Formaldehyd-Abspaltern sollte verzichtet werden können. It was therefore the object of the present invention to develop a transparent, aqueous cosmetic gel which can be thickened and preserved on the basis of natural raw materials.
