Abstract
Description
Die Erfindung betrifft die Verwendung von Cholesterin, cholesterinhaltigen Substanzen oder von den Cholesteringehalt der menschlichen Haut erhöhenden Substanzen in kosmetischen und dermatologischen Zubereitungen. The invention relates to the use of cholesterol, cholesterol-containing substances or from the cholesterol content of the human skin enhancing substances in cosmetic and dermatological preparations.
Cholesterin, das auch als 5-Cholesten-3β-ol oder Cholesterol
bezeichnet wird, ist als eine der Familie der Lipide zuzuordnende
Substanz bereits bestens bekannt. Mit der Summenformel C27H46O
und einem Molekulargewicht von 386,64 g/mol kristallisiert es in Form
farbloser Blättchen, die unter Normalbedingungen eine Dichte von
1,052 g/cm3 sowie einen Schmelzpunkt von 148,5 C aufweisen. Sein
Siedepunkt liegt bei 360°C. Als Lipid ist Cholesterin in polaren
Lösungsmitteln wie Wasser praktisch nicht löslich. In unpolaren
Lösungsmitteln wie Benzol oder Ether liegt hingegen eine gute
Löslichkeit vor. Es folgt eine Strukturformel von Cholesterin:
Cholesterol, also known as 5-cholesten-3β-ol or cholesterol, is already well known as a substance belonging to the family of lipids. With the molecular formula C 27 H 46 O and a molecular weight of 386.64 g / mol, it crystallizes in the form of colorless leaflets which, under normal conditions, have a density of 1.052 g / cm 3 and a melting point of 148.5 C. Its boiling point is 360 ° C. As a lipid, cholesterol is practically insoluble in polar solvents such as water. In contrast, there is good solubility in non-polar solvents such as benzene or ether. The following is a structural formula of cholesterol:
Cholesterin kommt in nahezu allen tierischen Zellen vor. Fischöle und Wollfett sind die bekanntesten Vertreter Cholesterin enthaltender Substanzen. Cholesterol is found in almost all animal cells. Fish oils and Wool fat are the best known representatives of cholesterol Substances.
Der Cholesteringehalt menschlicher Zellen beträgt im Mittel 0,32%, wobei sich Cholesterin beispielsweise im Gehirn, Rückenmark, in den Nebennieren oder im Blut findet. In großen Mengen ist es auch in den Gallensteinen vorhanden, aus denen es auch erstmals isoliert wurde. Cholesterin liegt entweder in freier Form vor oder ist mit höheren Fettsäuren verestert. The cholesterol content of human cells is 0.32% on average, where cholesterol is found in the brain, spinal cord, in the Adrenal glands or found in the blood. It is also available in large quantities in the Gallstones from which it was isolated for the first time. Cholesterol is either free or high Fatty acids esterified.
Die Gewinnung erfolgt durch Extraktion cholesterinhaltiger Substanzen wie beispielsweise gepulverter Gallensteine. Technisch wird Cholesterin beispielsweise aus Wollfett oder tierischem Rückenmark erhalten. The extraction takes place by extraction of cholesterol Substances such as powdered gallstones. Technically For example, cholesterol is made from wool fat or animal Preserved spinal cord.
Die Biosynthese von Cholesterin erfolgt ausgehend von Acetyl-CoA über Mevalonsäure, Squalen und Lanosterin hauptsächlich in der Leber aber auch in der Nebenrinde (Römpps Chemie Lexikon, 9. Auflage, Hrgs. Jürgen Falbe und Mafred Regitz, 1995, Thieme Verlag, Stuttgart). Cholesterol is biosynthesized from acetyl-CoA about mevalonic acid, squalene and lanosterol mainly in the Liver also in the minor cortex (Römpps Chemie Lexikon, 9. Edition, Hrgs. Jürgen Falbe and Mafred Regitz, 1995, Thieme Verlag, Stuttgart).
Es ist bekannt Cholesterin als Emulgator für kosmetische und pharmazeutische Präparate, Textilwaren, Lederpflegemittel, Haarwuchsmittel und für die Vitamin-D-Synthese zu verwenden. It is known as an emulsifier for cosmetic and cholesterol pharmaceutical preparations, textile goods, leather care products, Hair restorer and use for vitamin D synthesis.
Insbesondere ist bekannt, dass Cholesterin Bestandteil der Zellmembran ist, wobei dessen diesbezügliche Wirkungsweise und Bedeutung noch nicht vollständig aufgeklärt werden konnte. Es wurde jedoch nachgewiesen, dass ein Ansteigen des Cholesteringehalts zu einer Erhöhung der Viskosität der Zellmembran und damit zu einer Verringerung ihrer Durchlässigkeit für Wassermoleküle führt. In diesem Zusammenhang spielt offensichtlich auch die Orientierung der Moleküle an der Lipid/Wasser-Phasengrenze eine Rolle. Die Änderung der Membrandurchlässigkeit kann weiterhin die Aktivität oberflächenaktiver Enzyme oder zellmembranassoziierter Rezeptoren beeinflussen. In particular, it is known that cholesterol is a component of Cell membrane is, its related mode of action and Meaning could not be fully elucidated. It was however, it has been shown that an increase in cholesterol increases an increase in the viscosity of the cell membrane and thus to a Reducing their permeability to water molecules leads. In the orientation of the Molecules at the lipid / water phase boundary play a role. The Change in membrane permeability can continue activity surface-active enzymes or cell membrane-associated receptors influence.
In der Haut stellt Cholesterin einen wichtigen Bestandteil der epidermalen Permeabilitätsbarriere dar. Die teilungsfähigen Keratinozyten der Haut im Stratum Basale enthalten nur geringe Mengen an Lipiden, die hauptsächlich zu der Gruppe der Phospholipide, Cholesterine und Triglyceride gehören. Bei der Teilung und Differenzierung der Keratinozyten steigt deren Lipidgehalt durch eine Synthese von Fettsäuren, Phospholipiden, Glucosylceramiden und Cholesterin an. Die Lipide akkumulieren zu Lamellengranula, die bei der Umwandlung der Keratinozyten des Stratum granulosum in Korneozyten des Stratum corneum mit der Zellmembran fusioniern. Hierbei ergießt sich der aus Glycoproteinen, Glycolipiden, Phospholipiden, freien Sterolen und verschiedenen Hydrolasen bestehende Inhalt der Granula in den Interzellularraum. In the skin, cholesterol is an important component of the epidermal permeability barrier. The divisible Keratinocytes of the skin in the stratum basale contain only a small amount Amounts of lipids that mainly belong to the group of Phospholipids, cholesterols and triglycerides include. At the division and differentiation of the keratinocytes increases their lipid content a synthesis of fatty acids, phospholipids, glucosylceramides and cholesterol. The lipids accumulate into lamellar granules that in the conversion of the keratinocytes of the stratum granulosum into Merge coronocytes of the stratum corneum with the cell membrane. This pours out of glycoproteins, glycolipids, Phospholipids, free sterols and various hydrolases existing contents of the granules in the intercellular space.
Im Hinblick auf eine hautbezogene Verwendung ist es bekannt, Cholesterin oder cholesterinhaltige Substanzen wie Lanolin, das auch als Wollwachs bezeichnet wird, als Emulgator in kosmetischen oder dermatologischen Zubereitungen einzusetzen. With regard to skin-related use, it is known Cholesterol or cholesterol-like substances like lanolin, that too is referred to as wool wax, as an emulsifier in cosmetic or use dermatological preparations.
Aus der DE 43 28 828 ist beispielsweise ein Cholesterin enthaltendes Händedesinfektionsmittel bekannt, wobei das Cholesterin eine dahingehende Wirkung aufweist, dass ein starke Entwässerung der Haut auf Grund eines häufigen Desinfizierens der Hände vermieden wird. DE 43 28 828, for example, contains cholesterol Hand disinfectant known, the cholesterol one has the effect that a strong drainage of the Avoid skin due to frequent hand disinfection becomes.
Williams et al. beschreiben in Arch. Dermatol. Res. 123 (1987) auf den Seiten 1535-1538, dass die Verwendung von cholesterinsenkenden Mitteln wie Fluvastatin und Lovastatin zu Hyperplasie mit Abschälen und Entschuppung der Epidermis führt. Dabei hemmen die cholesterinsenkenden Mittel die HMG-CoA-Reductase als Leitenzym der Cholesterin-Synthese. Williams et al. describe in Arch. Dermatol. Res. 123 (1987) pages 1535-1538 that the use of cholesterol-lowering drugs such as fluvastatin and lovastatin to cause hyperplasia Peeling and desquamation of the epidermis leads. The inhibit cholesterol-lowering agent the HMG-CoA reductase as the leading enzyme cholesterol synthesis.
Pandy et al. konnten mir ihrer im ind. J. of Dermatol., Venerol and Leprology 60 (1994) auf den Seiten 130 bis 132 erschienenen Veröffentlichung eine clofazamininduzierte Ichthiose als Nebenwirkung einer Lepratherapie feststellen, die ebenfalls eine Folge der Hemmung der Cholesterinsynthese darstellt. Pandy et al. could you give me in ind. J. of Dermatol., Venerol and Leprology 60 (1994) on pages 130 to 132 Publication of a clofazamine-induced ichthiosis as Find a side effect of lepratherapy, which is also a Represents the inhibition of cholesterol synthesis.
Weiterhin ist bekannt, die Nebenwirkungen von den Cholesteringehalt senkenden Medikamenten durch topische Zugabe von Cholesterin zu behandeln. In diesem Zusammenhang sei auf die oben erwähnte Veröffentlichung von Pandy et al. sowie auf Menon et al. in J. Invest. Dermatol. 98 (1992), Seiten 209 bis 219 und auf Feingold et al. J. Invest. Dermatol. 96 (1991), Seiten 201 bis 209 verwiesen. It is also known the side effects of the cholesterol content lowering medication by adding cholesterol topically to treat. In this context, let's refer to the above Publication of Pandy et al. and on Menon et al. in J. Invest. Dermatol. 98 (1992), pages 209 to 219 and on Feingold et al. J. Invest. Dermatol. 96 (1991), pages 201 to 209.
Ghadially et al. offenbaren in J. Clin. Invest. 95 (1995) auf den Seiten 2281 bis 2290, dass bei älteren Menschen die Reparaturfähigkeit der Haut auf Grund einer abnehmenden Syntheserate gestört ist. Zettersen et al. beschrieben darauf hin in J. Am. Acad. Dermatol. 37 (1997) auf den Seiten 403 bis 408, dass Lipidzubereitungen mit einem hohen Cholesteringehalt die Reparaturfähigkeit der Haut bei älteren Menschen erhöhen. Ghadially et al. disclose in J. Clin. Invest. 95 (1995) on the pages 2281 to 2290 that in the elderly the repairability of the Skin is disturbed due to a decreasing synthesis rate. Zettersen et al. thereupon described in J. Am. Acad. Dermatol. 37 (1997) on pages 403 to 408 that lipid preparations with a high cholesterol the repairability of the skin in older Increase people.
Quiec et al. beschreiben in Biochem. J. 310 (1995) auf den Seiten 305 bis 309, dass der HMG-CoA-Reductase-Hemmstoff Lovastatin die Phototoxizität von UVA-Strahlung in kultivierten humanen Kreatinozyten erhöht. Dies konnte in diesen Experimenten sowohl durch Cholesterin als auch durch einen Cathepsin-Inhibitor wie E 64 verhindert werden. Quiec et al. describe in Biochem. J. 310 (1995) on the pages 305 to 309 that the HMG-CoA reductase inhibitor lovastatin the phototoxicity of UVA radiation in cultured human Creatinocytes increased. This could be done in both of these experiments by cholesterol as well as by a cathepsin inhibitor such as E 64 be prevented.
Wird die menschliche Haut einer langandauernden Sonnenstrahlung ausgesetzt, kann dies zu Licht- oder Photodermatosen in den unterschiedlichsten Formen führen. Beispielhaft seien hier Sonnenbrand, lichtinduzierte Hautalterung und Hautkrebs genannt. Die Photodermatosen auslösende Wirkung des Sonnenlichts wird unter anderem auf die in dem Sonnenlichtspektrum enthaltene UVA- Strahlung zurückgeführt, die darüber hinaus auch von künstlichen Strahlungsquellen beispielsweise eines Solariums ausgesandt wird. The human skin becomes a long-lasting sun radiation exposed to light or photodermatosis in the different forms. Examples are here Called sunburn, light-induced skin aging and skin cancer. The photodermatosis-triggering effect of sunlight is among other things on the UVA contained in the sunlight spectrum Radiation returned, moreover, also from artificial Radiation sources, for example a solarium, is emitted.
Zum Schutz vor UVA-Strahlung enthalten übliche Sonnenschutzmittel zur Ausbildung einer undurchlässigen Schicht auf der Haut Substanzen, die UV-Strahlung im Bereich von 280 bis 400 Nanometern absorbieren. Solche photoprotektive Substanzen sind beispielsweise Titandioxid oder Zimtsäurederivate. Common sunscreens are used to protect against UVA radiation to form an impermeable layer on the skin Substances that emit UV radiation in the range of 280 to Absorb 400 nanometers. Such photoprotective substances are, for example, titanium dioxide or cinnamic acid derivatives.
Neben reinen Absorbermolekülen weisen einige der vorbekannten Sonnenschutzmittel biologisch aktive Zusatzstoffe wie Antioxidantien, DNS-Reparaturenzyme oder Entzündungshemmer auf. Schließlich sind auch lanolinhaltige Sonnenschutzmittel bekannt. Das Cholesterin enthaltende Lanolin wird jedoch bei diesen Formulierungen lediglich als sogenanntes inertes Vehikel oder galenischer Bestandteil eingesetzt, dem als solcher keine Schutzwirkung beigelegt wird, sondern der lediglich zur Lösung oder sonstigen Aufnahme von Wirksubstanzen dient. In addition to pure absorber molecules, some of the known ones Sunscreen biologically active additives such as antioxidants, DNA repair enzymes or anti-inflammatories. Finally sunscreen agents containing lanolin are also known. The cholesterol Lanolin containing is only used in these formulations as a so-called inert vehicle or galenic component used, which as such is not accompanied by a protective effect, but only for the solution or other inclusion of Active substances serves.
Auch im Hinblick auf eine in der letzten Zeit stark zunehmende Intensität des UV-Anteils im Sonnenspektrum wäre es zur Herbeiführung eines möglichst umfassenden Hautschutzes wünschenswert, neben reinen Strahlungsabsorbern auf Substanzen zugreifen zu können, die eine abweichende oder ergänzende Schutzwirkung für die Haut entfalten. Also with regard to a recently increasing The intensity of the UV component in the sun spectrum would be To achieve the most comprehensive skin protection possible desirable, in addition to pure radiation absorbers on substances to be able to access a different or supplementary Develop protective effects for the skin.
Aufgabe der Erfindung ist es daher, den Hautschutz gegenüber schädlicher UVA-Strahlung zu verbessern. The object of the invention is therefore to protect the skin to improve harmful UVA radiation.
Zur Lösung dieser Aufgabe wird vorgeschlagen, Cholesterin, cholesterinhaltige Substanzen oder den Cholesteringehalt der menschlichen Haut erhöhende Substanzen in kosmetischen und dermatologischen Zubereitungen zur UV-Protektion zu verwenden. To solve this problem, cholesterol, cholesterol-containing substances or the cholesterol content of the human skin enhancing substances in cosmetic and use dermatological preparations for UV protection.
Die Erfindung fußt auf einer neu aufgefundenen Wirkung des Cholesterins, deren Nachweis nachfolgend umrissen werden soll. Aus der Veröffnentlichung von Grether-Beck et al. in Proc. Natl. Acad. Sci. USA 93 (1996), Seiten 14586 bis 14591, sowie von Grether-Beck et al. Biol. Chem. 378 (1997), Seiten 1231 bis 1236, ist bekannt, dass die UVA-Strahlung die Expression bestimmter Gene in den Keratinozyten auslöst. Die sich daraus ergebenden Genprodukte sind neben weiteren Einflussfaktoren maßgeblich für das unerwünschte Auftreten von Lichtdermatosen wie der polymorphen Lichtdermatose, Auftreten von Hautalterung und Hautkrebs. Beispielhaft sei die UVA- induzierte Expression des Entzündungsmarkers Interzelluläres Adhäsionsmolekül 1 genannt, auf das sich im Folgenden mit ICAM-1 bezogen wird. The invention is based on a newly discovered effect of Cholesterol, the detection of which will be outlined below. Out the publication by Grether-Beck et al. in proc. Natl. Acad. Sci. USA 93 (1996), pages 14586 to 14591, and by Grether-Beck et al. Biol. Chem. 378 (1997), pages 1231 to 1236, it is known that the UVA radiation expresses certain genes in the Triggers keratinocytes. The resulting gene products are in addition to other influencing factors decisive for the undesirable Occurrence of light dermatoses such as polymorphic light dermatosis, Occurrence of skin aging and skin cancer. The UVA induced expression of the inflammatory marker intercellular Adhesion molecule 1, referred to below with ICAM-1 is related.
Fig. 1 zeigt die zeitaufgelöste Expression des ICAM-1 in primären humanen Keratinozyten im Verhältnis zur Expression von β-Actin nach einer kontinuierlichen 10 bis 15 Minuten langen UVA- Bestrahlung mit einer Energiedichte von 30 J/cm2. Die untersuchten Keratinozyten waren somit einer Strahlendosis ausgesetzt, die derjenigen des Sonnenlichtes um die Mittagszeit an einem Sommertag in 30-35° nördlicher Breite über einen Zeitraum von 1 bis 2 Stunden hinweg im Wesentlichen entspricht. Es ist erkennbar, dass bereits nach einer halben Stunde der ICAM-1-Gehalt um das drei- bis vierfache zunimmt. Diese Einflussnahme der UVA-Strahlung auf die Genexpression der Keratinozyten, hier beispielhaft für ICAM-1 dargestellt, entspricht der initialen Veränderung, die bei der Entstehung von Lichtdermatosen wie der polymorphen Lichtdermatose sowie bei der Entstehung von Lichtalterung und Hautkrebs in der menschlichen Haut zu beobachten ist. Fig. 1 shows the time-resolved expression of ICAM-1 in primary human keratinocytes 2 shows in relation to the expression of β-actin after continuous 10 to 15 minutes long UVA irradiation at an energy density of 30 J / cm. The examined keratinocytes were thus exposed to a radiation dose which essentially corresponds to that of sunlight around noon on a summer day in a latitude of 30-35 ° N for a period of 1 to 2 hours. It can be seen that after just half an hour the ICAM-1 content increases three to four times. This influence of UVA radiation on the gene expression of the keratinocytes, shown here as an example for ICAM-1, corresponds to the initial change that can be observed in the development of light dermatoses such as polymorphic light dermatosis and in the development of light aging and skin cancer in human skin ,
Fig. 2 zeigt die auf β-Actin bezogene Expression von ICAM-1 in primären humanen Keratinozyten, die vor einer entsprechenden UVA- Bestrahlung in Cholesterin präinkubiert wurden. Durch den Zusatz von Cholesterin konnte auch nach einer halben Stunde keine Zunahme der Expression von ICAM-1 nachgewiesen werden. Bei längerem Zuwarten ergab sich sogar ein Rückgang der ICAM-1-Expression. Da die UVA-induzierte Genexpression, hier am Beispiel von ICAM-1 gezeigt, ein Maß für die Wahrscheinlichkeit des Auftretens von polymorphen Lichtdermatosen, Hautkrebs oder Hautalterung ist, konnte somit erstmals nachgewiesen werden, dass eine Präinkubation von primären normalen humanen Keratinozyten mit Cholesterin zu einer völligen Hemmung der UVA-induzierten Genexpression führt. Daraus folgt, dass Cholesterin eine bislang unbekannte photoprotektive Wirkung entfaltet. FIG. 2 shows the expression of ICAM-1 related to β-actin in primary human keratinocytes which were preincubated in cholesterol before a corresponding UVA irradiation. The addition of cholesterol showed no increase in ICAM-1 expression even after half an hour. With a longer wait, there was even a decrease in ICAM-1 expression. Since UVA-induced gene expression, shown here using the example of ICAM-1, is a measure of the likelihood of the occurrence of polymorphic light dermatoses, skin cancer or skin aging, it was therefore possible to demonstrate for the first time that preincubation of primary normal human keratinocytes with cholesterol leads to one results in complete inhibition of UVA-induced gene expression. It follows that cholesterol has a previously unknown photoprotective effect.
Ausgehend von dieser neu aufgefundenen Wirkung beruht die Erfindung auf der Idee, dass die menschliche Haut gegen unerwünschte UVA-induzierte Schädigungen dadurch geschützt werden kann, dass Cholesterin, cholesterinhaltige Substanzen oder Substanzen, die den Cholesteringehalt der Haut erhöhen, als photoprotektive Substanzen in Zubereitungen für die Haut und damit zum Zwecke der UV-Protektion verwendet werden. Based on this newly discovered effect, the Invention on the idea that human skin against this protects unwanted UVA-induced damage that can be cholesterol, cholesterol-containing substances or Substances that increase the cholesterol level in the skin than photoprotective substances in preparations for the skin and thus be used for the purpose of UV protection.
Die UV-Protektion besteht vorteilhafterweise darin, das Auftreten von Lichtdermatosen wie der polymorphen Lichtdermatose, der lichtinduzierten Hautalterung oder des lichtinduzierten Hautkrebses zu verhindern. The UV protection advantageously consists in the occurrence of Light dermatoses like the polymorphic light dermatosis, the light-induced skin aging or light-induced skin cancer prevent.
Bei einer zweckmäßigen Weiterentwicklung der Erfindung ist die dermatologische Zubereitung, ein übliches Sonnenschutzmittel, dem Cholesterin, eine cholesterinhaltige Substanz oder eine den Cholesteringehalt der menschlichen Haut erhöhende Substanz zusätzlich zugesetzt ist. Übliche Sonnenschutzmittel sind beispielsweise in den Druckschriften DE 199 19 630 A1, DE 199 37 299 A1 oder DE 196 41 274 offenbart. In an expedient further development of the invention dermatological preparation, a common sunscreen, the Cholesterol, a cholesterol-containing substance or a den Substance that increases the cholesterol level of human skin is additionally added. Common sunscreens are for example in the publications DE 199 19 630 A1, DE 199 37 299 A1 or DE 196 41 274.
Bei einem weiteren Ausführungsbeispiel ist die dermatologische Zubereitung eine Salbe, Creme oder Lotion, die cholesterinhaltige flexible Liposome also Lipsome mit fluiden Membranen aufweist. In another embodiment, the dermatological Preparation of an ointment, cream or lotion that contains cholesterol has flexible liposomes, ie lipomes with fluid membranes.
Abweichend hiervon weist die Salbe, Creme oder Lotion mikrosomal verkapseltes Cholesterin auf. Dabei stellen die flexiblen Liposome beziehungsweise die mikrosomale Verkapselung sicher, dass das Cholesterin bei einer topischen Anwendung in die unteren Hautschichten einschließlich des Stratum basale vordringt, um dort seine im Sinne der Erfindung vorteilhafte Wirkung zu entfalten. In deviation from this, the ointment, cream or lotion shows microsomally encapsulated cholesterol. The flexible liposomes or the microsomal encapsulation ensures that the Cholesterol when applied topically in the lower Skin layers including the basal stratum penetrates to there to develop its advantageous effect in the sense of the invention.
Bei einer diesbezüglichen Weiterentwicklung ist es auch möglich die Salbe, Creme oder Lotion okklusiv also beispielsweise unter Verwendung von Folien, Hydrokolloidverbänden oder sogenannten Sheets zu applizieren. With a related development, it is also possible Occlusive ointment, cream or lotion, for example, under Use of foils, hydrocolloid bandages or so-called To apply sheets.
Als cholesterinhaltige Substanz kann, sollte dies zweckdienlich sein, erfindungsgemäß Lanolin zum Einsatz gelangen. As a substance containing cholesterol, should this be useful, lanolin according to the invention are used.
Die Applikation des Cholesterins oder der wirkungsgleichen Substanzen auf die Haut oder Epidermis sollte sich nach der jeweiligen Zweckmäßigkeit richten und ist in diesem Sinne erfindungsgemäß beliebig, solange die Wechselwirkung zwischen dem erfindungsgemäßen Wirkstoff und den Keratinozyten sichergestellt ist und dieser durch die gewählte Galenik nicht von den Keratinozyten isoliert wird. So kann beispielsweise Cholesterin in einer Mischung aus Propylenglykol und Ethanol im Volumenverhältnis von 7 : 3 gelöst und auf die Haut beispielsweise mit einem Pinsel aufgetragen werden. Hierbei bildet die Aklohollösung ein Vehikel zum Verteilen der geringen Cholesterinmengen in der Größenordnung von 25 Gramm pro Liter. The application of cholesterol or the equivalent Substances on the skin or epidermis should look after the judge appropriate expediency and is in this sense according to the invention as long as the interaction between the active ingredient according to the invention and the keratinocytes is ensured and this is not prevented by the selected galenics Keratinocyte is isolated. For example, cholesterol in a mixture of propylene glycol and ethanol in volume ratio of 7: 3 and applied to the skin with a brush, for example be applied. Here the alcohol solution forms a vehicle for Distribution of low cholesterol levels on the order of 25 grams per liter.
Bei einem anderen Ausführungsbeispiel der Erfindung wird eine cholesterinhaltige Substanz bestehend aus Cholesterin, Ceramid, Palmitat, Oleat im Gewichtsverhältnis von 3 : 1 : 1 : 1 in einem Alkoholgemisch aus Propylenglycol und n-Propanol im Volumenverhältnis von 7 zu 3 gelöst, wobei der Gewichtsanteil der cholesterinhaltigen Substanz 2% bezogen auf die Gesamtmasse beträgt. In another embodiment of the invention, a cholesterol-containing substance consisting of cholesterol, ceramide, Palmitate, oleate in a weight ratio of 3: 1: 1: 1 in one Alcohol mixture of propylene glycol and n-propanol in the Volume ratio of 7 to 3 solved, the weight fraction of cholesterol-containing substance 2% based on the total mass is.
