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.
Aus der JP 30 14 505-A, Derwent Abstract 91-067928/10, ist ein Mittel bekannt, das niedere Glycerin-α-mono alkylether enthält und verwendet werden kann, um die Haut zu pflegen und Feuchtigkeit zurückzuhalten. Als geeignete Glycerinether werden die Methyl-, Ethyl-, Propyl- und Isopropylether genannt, die zur Gruppe der C₁-C₃-Alkylglycerinether gehören.From JP 30 14 505-A, Derwent Abstract 91-067928 / 10, is a known agent, the lower glycerol α-mono contains alkyl ether and can be used to skin maintain and retain moisture. As suitable glycerol ethers become the methyl, ethyl, propyl and isopropyl ethers mentioned belonging to the group of C₁-C₃ alkyl glycerol ethers.
In der JP 5 51 27 133, Derwent Abstract 80-81608 C/46, ist eine Emulgatorzusammensetzung für die kosmetische Verwendung beschrieben. Sie enthält unter anderem α,β-Hydroxydiol, wofür beispielhaft Glycerinmonoalkylether mit 8 bis 40 Kohlenstoffatomen in der Alkylgruppe angegeben sind. Über eine Funktion des Diols, abgesehen von dem Beitrag zur Emulgierwirkung, ist nichts ausgesagt. Vielmehr werden zusätzlich "Feuchthalte mittel" als weitere, gegebenenfalls vorhandene Bestandteile auf geführt, so daß davon auszugehen ist, daß die genannten Diol verbindungen nicht als "Feuchthaltemittel" angesehen werden.In JP 5 51 27 133, Derwent Abstract 80-81608 C / 46, is an emulsifier composition for the cosmetic Use described. It contains, inter alia, α, β-hydroxydiol, exemplified by glycerol monoalkyl ethers of 8 to 40 Carbon atoms are indicated in the alkyl group. Over a Function of the diol, apart from the contribution to the emulsifying effect, Nothing is stated. Rather, in addition "moistures medium "as further, optionally present constituents so that it can be assumed that the diol mentioned compounds are not considered to be "humectants".
Der Erfindung liegt die Aufgabe zugrunde, insbesondere kosmetische, 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 cosmetic, containing a suitable skin care additive cleaning and to provide 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 durch die Verwendung von 1-(2-Ethylhexyl)gly cerinether als Hautpflegeadditiv bzw. eine Reinigungs- und Pflege zusammensetzung gelöst, die neben den jeweils üblichen Bestandteilen 0,01 bis 10 Gew.-% 1-(2-Ethylhexyl)glycerinether als Hautpflegeadditiv enthält. This object is achieved by the use of 1- (2-ethylhexyl) gly cerinether as a skin care additive or a cleaning and care Composition solved in addition to the usual components 0.01 to 10 wt .-% 1- (2-ethylhexyl) glycerol ether as Skin care additive contains.
Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Preferred embodiments of the invention are the subject of Dependent claims.
Der erfindungsgemäß verwendete Glycerinmonoalkylether ist 1-(2-Ethylhexyl)glycerinether. Diese Verbindung ist leicht zugänglich. Ihre Herstellung ist in der Literatur beschrieben, z. B. in JP 80-19253, JP 58-134049, DE 33 43 530 und E. Baer, H. O. L. Fischer in J. Biol. Chem. 140, 397 (1941).The glycerol monoalkyl ether used in the invention is 1- (2-ethylhexyl) glycerol ether. This connection is easy to access. Their production is in the literature described, for. In JP 80-19253, JP 58-134049, DE 33 43 530 and E. Baer, H.O.L. Fischer in J. Biol. Chem. 140, 397 (1941).
Der Glycerinether wird erfindungsgemäß als Hautpflegeadditiv für Produkte aus dem kosmetischen und kosmetiknahen Bereich verwendet. 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 ether is according to the invention as skin care additive for products from the cosmetic and cosmetics-related area used. 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.
Der erfindungsgemäß verwendete Glycerinmonoalkylether nimmt aufgrund seines ambiphilen Charakters ähnlich wie die Monoglyceride eine Mittelstellung bezüglich der Hydrophilie/Lipophilie zwischen den oben erwähnten hydrophilen Komponenten und den reinen Fetten ein.The glycerol monoalkyl ether used according to the invention increases similar to monoglycerides due to its ambiphilic character a middle position with respect to the hydrophilicity / lipophilicity between the above-mentioned hydrophilic components and the pure fats.
Daraus resultiert, daß er in tensidhaltigen Produkten eine ausgeprägte rückfettende Wirkung zeigt, die nach der Anwendung zu einem an genehmen Hautgefühl führt. In den erforderlichen Einsatzkonzen trationen besitzen der genannte Glycerinmonoalkylether in den Zielprodukten eine gute Löslichkeit.As a result, he in surfactant-containing products a pronounced moisturizing effect, which after the application to a feels good. In the required operational plans the said glycerol monoalkyl ethers are present in the Target products have good solubility.
Darüber hinaus kommt dem erfindungsgemäß verwendeten Additiv als weitere hautpflegende Eigenschaft ein gewisses Feuchthalte vermögen zu. Dieser Effekt ist besonders ausgeprägt. In addition, the additive used in the invention comes as a further skin care property a certain moisturizing properties able to. This effect is particularly pronounced.
Bei dem erfindungsgemäß eingesetzten Glycerinether handelt es sich um eine in chemisch reiner Form herstellbare farb- und geruchs neutrale Verbindung. Es ist bei Raumtemperatur flüssig und läßt sich daher leicht in die Produkte einarbeiten.The glycerol ether used according to the invention is It is a color and smell that can be produced in a chemically pure form neutral connection. It is liquid at room temperature and leaves therefore easy to incorporate into the products.
Von besonderem Vorteil ist die im Vergleich zu Fettsäureestern, z. B. Mono- und Diglyceriden, größere chemische Stabilität des Glycerinmonoalkylethers. Bedingt durch seine Etherstruktur ist das erfindungsgemäße Hautpflegeadditiv 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 dem Glycerinmonoalkylether nicht zu befürchten.Of particular advantage compared to fatty acid esters, z. As mono- and diglycerides, greater chemical stability of Glycerol monoalkyl ether. Due to its ether structure that is skin care additive of 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 may occur is not the case with the glycerol monoalkyl ether fear.
Die Einsatzkonzentration des Glycerinmonoalkylethers liegt, bezogen auf das Produkt, im allgemeinen im Bereich von 0,01 bis 10 Gew.-%, bevorzugter 0,05 bis 5 Gew.-%. Wenn der Glycerin monoalkylether in erster Linie als Rückfetter in tensidhaltigen Formulierungen eingearbeitet ist, liegt er 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 ether 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 is incorporated, it is 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 kommt der erfindungsgemäße Glycerinmonoalkylether auch als Lipid-Komponenten für o/w- oder w/o-Emulsionen wie Pflegecremes und -emulsionen in Betracht. Der Glycerinmono alkylether wird 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 is the 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 ether is 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 des Glycerinmonoalkylethers 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 Glycerinmonoalkylethers as a lipid component and as moisturizing component particularly to advantage.
