Description
Die Erfindung betrifft die Verwendung von Fettsäure-N-alkyl glykosylamiden zur Herstellung von Hautpflegemitteln.The invention relates to the use of fatty acid N-alkyl Glycosylamides for the preparation of skin care products.
Für die Elastizität und das Aussehen der Haut spielt ein aus balancierter Wasserhaushalt in den einzelnen Hautschichten eine wichtige Rolle. In der Dermis und in der Grenzschicht der Epidermis nahe der Basalmembran ist der Gehalt an gebun denem Wasser am größten. Die Hautelastizität wird entschei dend durch die Collagenfibrillen in der Dermis geprägt, wobei die spezifische Konformation des Collagens durch den Einbau von Wassermolekülen erreicht wird. Eine Zerstörung der Lipid barriere im Stratum Corneum (SC) beispielsweise durch Tenside führt zu einem Anstieg des transepidermalen Wasserverlustes, wodurch die wäßrige Umgebung der Zellen gestört wird. Da das in tieferen Hautschichten gebundene Wasser nur über Gefäße über die Körperflüssigkeit, nicht aber von außen zugeführt werden kann, wird deutlich, daß der Erhalt der Barrierefunk tion des Stratum Corneum essentiell für den Gesamtzustand der Haut ist [vgl. S.E. Friberg et al, C.R. 23. CED-Kongress, Barcelona, 1992, 5.29].For the elasticity and the appearance of the skin one plays out balanced water balance in the individual skin layers an important role. In the dermis and in the boundary layer the epidermis near the basal membrane is the content of gebun largest water. The skin elasticity is decided characterized by the collagen fibrils in the dermis, wherein the specific conformation of collagen through incorporation of water molecules is achieved. A destruction of the lipid barrier in the stratum corneum (SC), for example, by surfactants leads to an increase in transepidermal water loss, whereby the aqueous environment of the cells is disturbed. Since that Water bound in deeper skin layers only via vessels via the body fluid, but not supplied from the outside it becomes clear that the receipt of the barrier radio Stratum corneum is essential for the overall condition of the Skin is [cf. S.E. Friberg et al, C.R. 23rd CED Congress, Barcelona, 1992, 5.29].
Ceramide stellen liphophile Amide langkettiger Fettsäuren dar, die sich im allgemeinen von Sphingosin bzw. Phytosphin gosin ableiten. Erhebliche Bedeutung hat diese Klasse von körpereigenen Fettstoffen gewonnen, seitdem man sie zusammen mit den Corneocyten als Schlüsselkomponenten für den Aufbau des Lipid-Bilayers, also der Permeabilitätsbarriere, im Stra tum Corneum der menschlichen Haut erkannt hat. Ceramide haben Molekulargewichte von deutlich unter 1000, so daß bei äußerer Zufuhr in einer kosmetischen Formulierung das Erreichen des Wirkortes möglich ist. Die externe Applikation von Ceramiden führt zur Restaurierung der Lipidbarriere, wodurch den ge schilderten Störungen der Hautfunktion ursächlich entgegenge wirkt werden kann [vgl. R.D. Petersen, Cosm. Toil. 107, 45 (1992)).Ceramides are lipophilic amides of long-chain fatty acids which are generally sphingosine or phytosphine derive gosine. Significant importance of this class of The body's own fats have been extracted ever since with the corneocytes as key components for the construction the lipid bilayer, so the permeability barrier, in the Stra Tum Corneum has recognized the human skin. Have ceramides Molecular weights of well below 1000, so that when external Feed in a cosmetic formulation achieving the Place of action is possible. The external application of ceramides leads to the restoration of the lipid barrier, whereby the ge described disorders of the skin function causal opposite can be acted [vgl. R.D. Petersen, Cosm. Toil. 107, 45 (1992)).
Dem Einsatz von Ceramiden sind infolge ihrer mangelnden Ver fügbarkeit bislang Grenzen gesetzt. Es hat daher bereits Ver suche gegeben, ceramidanaloge Strukturen, sogenannte synthetische Lipidbarrieren ("synthe tic barrier lipids (SBL)" oder "Pseudoceramide") zu syntheti sieren und zur Hautpflege einzusetzen [vgl. G. Imokawa et al. J. Soc. Cosmet. Chem. 40, 273 (1989)].The use of ceramides are due to their lack Ver Availability has hitherto been limited. It therefore already has Ver search, ceramide analogous structures, so-called synthetic lipid barriers ("synthe tic barrier lipids (SBL) "or" pseudoceramides ") to syntheti and to use for skin care [cf. G. Imokawa et al. J. Soc. Cosmet. Chem. 40, 273 (1989)].
So werden beispielsweise in der Europäischen Offenlegungs schriften EP-A 0 277 641 und EP-A 0 227 994 Ceramidana loge der folgenden Struktur vorgeschlagen: For example, in the European Disclosure EP-A 0 277 641 and EP-A 0 227 994 Ceramidana loge of the following structure:
Aus den Europäischen Offenlegungsschriften EP-A1 0 482 869 und EP-A1 0 495 624 sind ceramidverwandte Strukturen der folgenden Formel bekannt (zur Erklärung der Indices sei auf die Schrift verwiesen):From European published patent applications EP-A1 0 482 869 and EP-A1 0 495 624 are ceramide-related structures of following formula (to explain the indices be on the Scriptures referenced):
Für den Schutz von Haut und Haaren werden in der Europäischen Patentanmeldung EP-A2 0 455 429 ferner Zuckerderivate der folgenden Zusammensetzung vorgeschlagen (zur Erklärung der Indices sei auf die Schrift verwiesen):For the protection of skin and hair are used in the European Patent application EP-A2 0 455 429 further sugar derivatives of following composition (to explain the Indices are referred to the Scriptures):
Gemäß der Lehre der Deutschen Patentanmeldung DE-A1 42 38 032 kommen als feuchtigkeitsregulierende Stoffe schließ lich auch langkettige, ethoxylierte Bernsteinsäurederivate in Betracht.According to the teaching of German Patent Application DE-A1 42 38 032 come as moisture-regulating substances close Lich long-chain, ethoxylated succinic acid derivatives into consideration.
Ungeachtet dieser Versuche ist der Erfolg, der sich mit die sen Stoffen erzielen läßt, bislang unbefriedigend; insbeson dere wird das Leistungsvermögen natürlicher Ceramide nicht erreicht. Ferner sind die Synthesesequenzen technisch aufwen dig und daher kostspielig, was die Bedeutung der Substanzen zusätzlich relativiert.Regardless of these attempts, the success that comes with the substances, so far unsatisfactory; insbeson The performance of natural ceramides will not increase reached. Furthermore, the synthetic sequences are technically aufwen dig and therefore costly, what the importance of substances additionally relativized.
Die Aufgabe der Erfindung hat somit darin bestanden, neue leistungsstarke ceramidanaloge Strukturen zu entwickeln, die sich durch eine möglichst einfache Synthese auszeichnen. Eine weitere Aufgabe hat ferner darin bestanden, die neuen Pseudo ceramide auf Basis nicht-tierischer Rohstoffe herzustellen.The object of the invention thus consisted of new to develop powerful ceramide analogues that are characterized by the simplest possible synthesis. A another task was to pass the new pseudo ceramides based on non-animal raw materials.
Gegenstand der Erfindung ist die Verwendung von Fettsäure-N- alkylglykosylamiden der Formel (I),The invention relates to the use of fatty acid N- alkylglycosylamides of the formula (I)
in der R¹CO für einen aliphatischen Acylrest mit 12 bis 18 Kohlenstoffatomen, R² für einen Alkyl- oder Hydroxyalkylrest mit 8 bis 18 Kohlenstoffatomen und [Z] für einen Glykosylrest mit 6 bis 12 Kohlenstoffatomen steht, als "synthetische Lipidbarrieren" in Hautpflegemitteln. in the R¹CO for an aliphatic acyl radical having 12 to 18 Carbon atoms, R² is an alkyl or hydroxyalkyl radical with 8 to 18 carbon atoms and [Z] for a glycosyl radical with 6 to 12 carbon atoms, as "synthetic lipid barriers" in skin care products.
Überraschenderweise wurde gefunden, daß die im Sinne der Er findung einzusetzenden Fettsäure-N-alkylglykosylamide die natürliche Barrierefunktion der Haut stärken, die Haut festi gen und vor Austrocknung schützen. Die Stoffe sind den natür lichen Hautlipiden nachempfunden, dermatologisch und ökotoxi kologisch unbedenklich und lassen sich homogen in die Ölphase kosmetischer Mittel einarbeiten. Sie sind weiß bzw. elfen beinartig gefärbt, geruchsfrei, im Bereich des Haut-pH-Wertes hydrolysebeständig und farbstabil gegen Luftsauerstoff. Die Erfindung schließt die Erkenntnis ein, daß die Alkylglykosyl amide auf Basis pflanzlicher Fettsäuren und Zucker, also ohne Mitverwendung unerwünschter tierischer Rohstoffe, hergestellt werden können.Surprisingly, it was found that in the sense of He Fatty acid N-alkylglycosylamides to be used strengthen the natural barrier function of the skin, firm the skin protect against dehydration. The substances are natural mimicking skin lipids, dermatological and ecotoxic ecologically harmless and can be homogeneously in the oil phase to incorporate cosmetic products.
