Description

Die Erfindung betrifft Verbindungen, die als Hautpflegeadditiv in Reinigungs- und Pflegeprodukten insbesondere aus dem kosme­ tiknahen und dem kosmetischen Bereich eingesetzt werden können.The invention relates to compounds useful as a skin care additive in cleaning and care products especially from the kosme tiknahen and the cosmetic field can be used.

Veränderte Lebensgewohnheiten verbunden mit einem gestiegenen Hygienebewußtsein haben in jüngerer Zeit zur vermehrten Anwendung von kosmetischen Reinigungs- und Pflegeprodukten, wie z. B. Seifen, Dusch- und Badepräparaten geführt. Je häufiger derartige seifen- bzw. tensidhaltige Produkte auf der Haut angewandt werden, desto deutlicher treten deren nachteilige Wirkungen, nämlich die Entfettung und Austrocknung der Haut durch die Zerstörung des Hydro-Lipid-Mantels, in den Vordergrund.Changing lifestyles associated with a risen Hygiene awareness has recently become more widespread of cosmetic cleaning and care products, such. B. Soaps, shower and bathing preparations. The more common such soap or surfactant-containing products applied to the skin the more obvious are their adverse effects, namely the degreasing and dehydration of the skin through the Destruction of the hydro-lipid coat, in the foreground.

Für eine optimale dermatologische Verträglichkeit derartiger Produkte sind daher pflegende Zusätze mit rückfettenden und feuchtigkeitsspendenden Eigenschaften notwendig.For optimal dermatological compatibility of such Products are therefore caring additives with moisturizing and moisturizing properties necessary.

Nach Anwendung der oben erwähnten Reinigungs- und Pflegeprodukte sorgen Emulsionen des o/w- (Öl in Wasser) oder w/o- (Wasser in Öl) Typs für eine Regulierung des Lipid- und Feuchtigkeits­ haushalts der Haut. Auch für diese Produkte ist eine sorgfältige Auswahl der Lipid-Komponenten und weiterer pflegender Zusätze, abgestimmt auf bestimmte Hauttypen, erforderlich.After applying the above-mentioned cleaning and care products Ensure emulsions of o / w (oil in water) or w / o (water in Oil) type for regulation of lipid and moisture Household of the skin. Also for these products is a careful  Selection of lipid components and other care additives, matched to certain skin types, required.

Der Erfindung liegt die Aufgabe zugrunde, insbesondere kosmeti­ sche, ein geeignetes Hautpflegeadditiv enthaltende Reinigungs- und Pflegeprodukte zur Verfügung zu stellen, bei denen das Hautpflegeadditiv selbst bei häufiger Produktanwendung ein Austrocknen der Haut verhindert und den Feuchtigkeitsgehalt reguliert, gleichzeitig aber die Haut in ausreichendem Ausmaß rückfettet und darüber hinaus auch noch ein angenehmes Hautgefühl vermittelt.The invention is based on the object, in particular cosmeti containing a suitable skin care additive To provide cleaning and care products in which the Skin care additive even with frequent product use Drying of the skin prevents and the moisture content regulates, but at the same time the skin sufficiently Greases and also a pleasant skin feeling taught.

Diese Aufgabe wird dadurch gelöst, daß als Hautpflegeadditiv Glycerinmonoalkylether verwendet werden.This object is achieved in that as skin care additive Glycerol monoalkyl ethers are used.

Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Preferred embodiments of the invention are the subject of Dependent claims.

Die erfindungsgemäß verwendeten Glycerinmonoalkylether besitzen die allgemeine FormelThe glycerol monoalkyl ethers used according to the invention have the general formula

in der R ein gerad- oder verzweigtkettiger Alkylrest mit 3 bis 14, insbesondere 5 bis 12 und vorzugsweise 7 bis 12 Kohlenstoff­ atomen ist. Hierzu gehören beispielsweise 1-Heptylglycerinether, 1-(2-Ethylhexyl)glycerinether, 1-Octylglycerinether, 1-Decyl­ glycerinetherund 1-Dodecylglycerinether, wobei 1-(2-Ethylhexyl)­ glycerinether besonders bevorzugt ist. Diese Verbindungen sind leicht zugänglich. Ihre Herstellung ist in der Literatur beschrieben, z. B. in JP 80-19 253, JP 58-1 34 049, DE 33 43 530 und E. Baer, H.O.L. Fischer in J. Biol. Chem. 140 397 (1941).in the R a straight or branched chain alkyl radical with 3 bis 14, in particular 5 to 12 and preferably 7 to 12 carbon is atoms. These include, for example, 1-heptylglycerol ether, 1- (2-ethylhexyl) glycerol ether, 1-octyl glycerol ether, 1-decyl glycerol ether and 1-dodecylglycerol ether, wherein 1- (2-ethylhexyl) glycerol ether is particularly preferred. These connections are easy to access. Their production is in the literature described, for. In JP 80-19 253, JP 58-1 34 049, DE 33 43 530 and E. Baer, H.O.L. Fischer in J. Biol. Chem. 140, 397 (1941).

Die erfindungsgemäß eingesetzten Glycerinether können ins­ besondere als Hautpflegeadditiv für Produkte aus dem kosmetischen und kosmetiknahen Bereich verwendet werden. Hierzu gehören z . B. Reinigungs- und Pflegeprodukte wie feste oder flüssige Seifen, Duschbäder, Duschgele, Schaumbäder, Shampoos, Waschlotionen, Tagescremes, Pflegecremes, Pflegeemulsionen, Aftershave-Lösungen bzw. -emulsionen und Handgeschirrspülmittel.The glycerol ethers used in the invention can in Special as skin care additive for products from the cosmetic  and cosmetics-related area. These include z. B. Cleaning and care products such as solid or liquid soaps, Shower baths, shower gels, bubble baths, shampoos, washing lotions, Day creams, care creams, care emulsions, aftershave solutions or emulsions and hand dishwashing detergents.

Im allgemeinen kommen für derartige Systeme nur hinreichend hydrophile Lipid-Komponenten als Rückfetter in Frage, weil stärker lipophile Substanzen wie Öle und Fette in derartigen Systemen eine zu geringe Löslichkeit aufweisen.In general, such systems are only adequate hydrophilic lipid components as a moisturizer in question, because more lipophilic substances such as oils and fats in such Systems have too low a solubility.

Nachdem die Alkanolamide wegen der Nitrosamin-Problematik weniger gern eingesetzt werden, werden als hydrophile Rückfetter für tensidhaltige Produkte u. a. ethoxylierte Alkohole sowie ethoxy­ lierte Mono-, Diglyceride und Triglyceride verwendet.After the alkanolamides because of the nitrosamine problem less like to be used as a hydrophilic moisturizer for surfactant-containing products u. a. ethoxylated alcohols and ethoxy lated mono-, diglycerides and triglycerides used.

Die erfindungsgemäß verwendeten Glycerinmonoalkylether nehmen aufgrund ihres ambiphilen Charakters ähnlich wie die Monoglyceri­ de eine Mittelstellung bezüglich der Hydrophilie/Lipophilie zwischen den oben erwähnten hydrophilen Komponenten und den reinen Fetten ein.Take the glycerol monoalkyl ethers used in the invention because of their ambiphilic character similar to the monoglyceri de an intermediate position with respect to the hydrophilicity / lipophilicity between the above-mentioned hydrophilic components and the pure fats.

Daraus resultiert, daß insbesondere die Glycerinmonoalkylether, bei denen der Alkylrest 8 bis 14, insbesondere 8 bis 12 Kohlen­ stoffatome enthält, in tensidhaltigen Produkten eine ausgeprägte rückfettende Wirkung zeigen, die nach der Anwendung zu einem an­ genehmen Hautgefühl führt. In den erforderlichen Einsatzkonzen­ trationen besitzen die genannten Glycerinmonoalkylether in den Zielprodukten eine gute Löslichkeit.As a result, in particular the glycerol monoalkyl ethers, in which the alkyl radical 8 to 14, in particular 8 to 12 carbon atoms contains, in surfactant-containing products a pronounced moisturizing effect, which after the application to a feels good. In the required operational plans The mentioned glycerol monoalkyl ethers have the abovementioned Target products have good solubility.

Darüber hinaus kommt den erfindungsgemäß verwendeten Additiven als weitere hautpflegende Eigenschaft ein gewisses Feuchthalte­ vermögen zu. Dieser Effekt ist bei den kürzerkettigen Derivaten, bei denen R ein Alkylrest mit 3 bis 8, insbesondere 5 bis 8 Kohlenstoffatomen ist, besonders ausgeprägt. In addition, the additives used in the invention comes as a further skin care property a certain moisturizing properties able to. This effect is with the shorter-chain derivatives, in which R is an alkyl radical having 3 to 8, in particular 5 to 8 Carbon atoms is, especially pronounced.  

Bei den erfindungsgemäß eingesetzten Glycerinethern handelt es sich um in chemisch reiner Form herstellbare farb- und geruchs­ neutrale Verbindungen. Derivate mit einem Alkylrest mit bis zu 9 Kohlenstoffatomen sind bei Raumtemperatur flüssig und lassen sich daher besonders leicht in die Produkte einarbeiten.The glycerol ethers used according to the invention are to be produced in chemically pure form color and smell neutral connections. Derivatives with an alkyl radical with up to 9 carbon atoms are liquid at room temperature and leave Therefore, it is particularly easy to work into the products.

Von besonderem Vorteil ist die im Vergleich zu Fettsäureestern, z. B. Mono- und Diglyceriden, größere chemische Stabilität der Glycerinmonoalkylether. Bedingt durch ihre Etherstruktur sind die erfindungsgemäßen Hautpflegeadditive auch im alkalischen Bereich einsetzbar. Dies ist besonders vorteilhaft für den Einsatz in flüssigen Seifen, wo es bei hohen pH-Werten und großem Wasser­ gehalt zur Hydrolyse der Glyceride unter Freisetzung von Fett­ säuren kommt, was sich u. a. in einer schlechten Kältestabilität der entsprechenden Produkte äußert. Auch eine enzymatische Spal­ tung unter Freisetzung von Fettsäuren, die bei den Glyceriden auftreten kann, ist bei den Glycerinmonoalkylethern nicht zu befürchten.Of particular advantage compared to fatty acid esters, z. As mono- and diglycerides, greater chemical stability of Glycerol monoalkyl. Due to their ether structure are the Skincare additives according to the invention also in the alkaline range used. This is especially beneficial for use in liquid soaps, where it is at high pH and large water content to hydrolyze the glycerides to release fat acids, what u. a. in a bad cold stability corresponding products. Also an enzymatic spal under release of fatty acids, which in the glycerides can occur, is not in the Glycerinmonoalkylethern fear.

Die Einsatzkonzentration der Glycerinmonoalkylether liegt, bezogen auf das Produkt, im allgemeinen im Bereich von 0,01 bis 10 Gew.-%, bevorzugter 0,05 bis 5 Gew.-%. Wenn die Glycerin­ monoalkylether in erster Linie als Rückfetter in tensidhaltigen Formulierungen eingearbeitet sind, liegen sie vorzugsweise in einer Menge von 0,2 bis 5 Gew.-%, bevorzugter 0,5 bis 3 Gew.-% vor. Die Einsatzkonzentration richtet sich hierbei nach Art und Konzentration der waschaktiven Substanzen und der weiteren Additive sowie nach der Stärke des gewünschten rückfettenden Effekts.The use concentration of the glycerol monoalkyl ethers is based on the product, generally in the range of 0.01 to 10% by weight, more preferably 0.05 to 5% by weight. When the glycerin monoalkyl ethers primarily as backfat in surfactant-containing Formulations are incorporated, they are preferably in in an amount of 0.2 to 5% by weight, more preferably 0.5 to 3% by weight in front. The use concentration depends on the type and Concentration of the washing-active substances and the others Additives as well as according to the strength of the desired moisturizing Effect.

Neben der oben erwähnten Anwendung in Seifen oder tensidhaltigen Produkten kommen die erfindungsgemäßen Glycerinmonoalkylether auch als Lipid-Komponenten für o/w- oder w/o-Emulsionen wie Pflegecremes und -emulsionen in Betracht. Die Glycerinmono­ alkylether werden bei der Herstellung des jeweiligen Produkts der Fettphase vorzugsweise in einer Menge von 0,05 bis 5, bevorzugter 0,5 bis 3 Gew.-%, jeweils bezogen auf das Endprodukt zugegeben. Nach Anwendung der Emulsion verbleibt ein sehr angenehmes, glattes Hautgefühl.In addition to the above-mentioned application in soaps or surfactant-containing Products come Glycerinmonoalkylether invention also as lipid components for o / w or w / o emulsions such as Care creams and emulsions into consideration. The glycerol mono Alkyl ethers are used in the preparation of the respective product of Fat phase preferably in an amount of 0.05 to 5, more preferably  0.5 to 3 wt .-%, each based on the final product added. After application of the emulsion remains a very pleasant, smooth skin feeling.

Besonders vorteilhaft ist die Verwendung des erfindungsgemäßen Hautpflegeadditivs in Aftershave-Formulierungen. Hierunter fallen sowohl die viel Alkohol enthaltenden Produkte als auch die modernen Aftershave-Emulsionen. In diesen Produkten kommt die Funktion der Glycerinmonoalkylether als Lipid-Komponente und als feuchtigkeitsspendende Komponente besonders zur Geltung.Particularly advantageous is the use of the invention Skin care additives in aftershave formulations. Fall under this Both the much alcohol-containing products and the modern aftershave emulsions. In these products comes the Function of Glycerinmonoalkylether as a lipid component and as moisturizing component particularly to advantage.
