"E ulgatorkonzentrat""E ulgator concentrate"
Die Erfindung betrifft ein klares, flüssiges, bei Temperaturen von 10 bis 35 °C gegen Austrübung stabiles Emulgatorkonzentrat auf Basis von Sterinen und/oder Wollwachsalkoholen sowie verzweigten, gesättigten Alkoholen mit 16 bis 20 C-Atomen.The invention relates to a clear, liquid, at temperatures of 10 to 35 ° C. stable emulsifier concentrate based on sterols and / or wool wax alcohols and branched, saturated alcohols with 16 to 20 carbon atoms.
Sterine und Wollwachsalkohole sind bekannte Hilfsmittel zur Herstellung kosmetischer und pharmazeutischer Zubereitungen. Insbesondere finden sie Verwendung zur Herstellung von Wasser-in-Öl- und Öl-in-Wasser-Emulsionen, die zum Beispiel in Form von Cremes in den Handel kommen. Zur Herstellung derartiger Zubereitungen werden häufig handelsübliche Emulgatorkonzentrate eingesetzt, die Sterine oder Wollwachsalkohole in einem aus Paraffinöl bestehenden Träger enthalten. Derartige Konzentrate sind jedoch bei Nor¬ maltemperatur trübe und müssen vor der weiteren Verarbeitung gleichmäßig verrührt und erhitzt werden. D. Kruse et al. haben nun zwar gezeigt, daß sich die Löslichkeit von Lanolin, das chemisch ein komplexes Gemisch von Estern darstellt, in pharmazeutischen Weißölen durch Hexadecylalkohol bei Raumtemperatur (25 °C) verbessern läßt (Seifen-Öle-Fette-Wachse, 1971 [97] 827). Sie haben jedoch keine Untersuchungen zur Löslichkeit von Lanolin¬ alkoholen (Wollwachsalkoholen) in Hexadecylalkohol durchgeführt. Ebenso¬ wenig liegen Erkenntnisse bei Temperaturen unterhalb Raumtemperatur vor. Es wäre jedoch wünschenswert, die Einsatzmöglichkeiten von Emulgatorkon- zentraten auf Basis von Sterinen und Wollwachsalkoholen dadurch zu ver¬ bessern, daß sie in einem weiten Temperaturbereich gegen Austrübungen stabil sind und dadurch vorteilhaft verarbeitet werden können.Sterols and wool wax alcohols are known auxiliaries for the production of cosmetic and pharmaceutical preparations. In particular, they are used for the production of water-in-oil and oil-in-water emulsions, which are commercially available, for example, in the form of creams. Commercial emulsifier concentrates which contain sterols or wool wax alcohols in a carrier consisting of paraffin oil are frequently used to produce such preparations. However, such concentrates are cloudy at normal temperature and must be stirred and heated evenly before further processing. D. Kruse et al. have now shown that the solubility of lanolin, which is a chemically complex mixture of esters, in pharmaceutical white oils can be improved by hexadecyl alcohol at room temperature (25 ° C) (soap-oil-fat waxes, 1971 [97] 827) . However, they have not carried out any studies on the solubility of lanolin alcohols (wool wax alcohols) in hexadecyl alcohol. There is also no knowledge at temperatures below room temperature. However, it would be desirable to improve the possible uses of emulsifier concentrates based on sterols and wool wax alcohols in that they are stable against clouding over a wide temperature range and can therefore be processed advantageously.
Es bestand daher die Aufgabe, klare, flüssige, bei Normaltemperatur gegen Austrübung stabile Emulgatorkonzentrate mit einem Gehalt an Sterinen und/oder Wollwachsalkoholen zur Verfügung zu stellen. Unter Normaltempe¬ ratur wird dabei ein Temperaturbereich von 10 bis 35 °C verstanden.It was therefore an object to provide clear, liquid emulsifier concentrates which are stable at normal temperature against clouding and contain sterols and / or wool wax alcohols. Normal temperature is understood to mean a temperature range from 10 to 35 ° C.
Diese Aufgabe wurde erfindungsgemäß gelöst durch ein klares, flüssiges, bei Normaltemperatur gegen Austrübung stabiles Emulgatorkonzentrat umfas¬ sendThis object has been achieved according to the invention by a clear, liquid emulsifier concentrate which is stable at normal temperature against clouding
(A) 7 bis 15 Gew.-% eines Alkohols ausgewählt aus der Gruppe der Sterine und Wollwachsalkohole(A) 7 to 15% by weight of an alcohol selected from the group of sterols and wool wax alcohols
(B) 85 bis 93 Gew.-% eines verzweigten, gesättigten Alkohols mit 16 bis 20 C-Atomen.(B) 85 to 93% by weight of a branched, saturated alcohol having 16 to 20 carbon atoms.
Die erfindungsgemäßen Emulgatorkonzentrate liegen in einem weiten Tempe¬ raturbereich von 10 bis 35 °C in klarer, flüssiger Form vor. Dies bedeutet eine erhebliche Verbesserung gegenüber den herkömmlichen Emulgatorkonzen- traten auf Basis von Sterinen bzw. Wollwachsalkoholen in einem Träger aus Mineralöl, da die letztgenannten Produkte erst bei höheren Temperaturen in klarer Form vorliegen.The emulsifier concentrates according to the invention are in a clear, liquid form in a wide temperature range from 10 to 35 ° C. This means a considerable improvement over the conventional emulsifier concentrates based on sterols or wool wax alcohols in a mineral oil carrier, since the latter products are only in a clear form at higher temperatures.
Unter den erfindungsgemäß einzusetzenden Ster nen sind Steroide zu ver¬ stehen, bei denen sich am dritten C-Atom des Steroidgerüstes eine Hydro¬ xylgruppe befindet und die daher chemisch den Alkoholen zuzurechnen sind. Die Steroide treten in allen tierischen und pflanzlichen Zellen auf. Nach ihren Vorkommen teilt man sie in Zoosterine, zum Beispiel Cholesterin, und Phytosterine, die vorwiegend in höheren Pflanzen vorkommen, auf. Unter Wollwachsalkoholen sind im Sinne des Deutschen Arzneimittelbuches (9. Ausgabe) komplexe Gemische von Sterinen und aliphatischen Alkoholen aus dem Wollwachs zu verstehen.The stars to be used according to the invention are steroids in which there is a hydroxyl group on the third carbon atom of the steroid structure and which are therefore chemically attributable to the alcohols. The steroids occur in all animal and plant cells. According to their occurrence, they are divided into zoosterols, for example cholesterol, and phytosterols, which are predominantly found in higher plants. In the sense of the German Medicinal Products Book (9th edition), wool wax alcohols are understood to mean complex mixtures of sterols and aliphatic alcohols from wool wax.
Als verzweigte, gesättigte Alkohole (B) kommen beispielsweise 2- Hexyldecanol, 2-0ctyldodecanol oder andere verzweigte, gesättigte Alkohole mit 16 bis 20 C-Atomen in Frage. Bevorzugt geeignet ist z.B. 2- Hexyldecanol, das von der Anmelderin unter der Bezeichung Eutanol G 16 vertrieben wird. Besonders gut geeignet sind aber diejenigen erfindungsgemäßen Emulgatorkonzentrate, worin der Alkohol (B) 2- Octyldodecanol ist und von der Anmelderin unter der Bezeichnung Eutanol G vertrieben wird.Examples of suitable branched, saturated alcohols (B) are 2-hexyldecanol, 2-0ctyldodecanol or other branched, saturated alcohols having 16 to 20 carbon atoms. Preferably, e.g. 2- Hexyldecanol, which is sold by the applicant under the name Eutanol G 16. However, those emulsifier concentrates according to the invention in which the alcohol (B) is 2-octyldodecanol and are marketed by the applicant under the name Eutanol G are particularly well suited.
Die erfindungsgemäßen Emulgatorkonzentrate lassen sich vorteilhaft zur Herstellung kosmetischer oder pharmazeutischer Zubereitungen verwenden. Insbesondere eignen sie sich zur Herstellung von Zubereitungen in der Form von Emulsionen, vorzugsweise vom Typ der Wasser-in-Öl-Emulsionen. Die auf Basis der erfindungsgemäßen Emulgatorkonzentrate hergestellten kosmeti¬ schen oder pharmazeutischen Emulsionen zeichnen sich insbesondere durch eine gute Lagerstabilität aus. Unter Lagerstabilität wird dabei verstan¬ den, daß die Emulsionen nach mehrmonatiger Lagerung keine Trennungs- bzw. Aufrahmerscheinungen zeigen und daß die Konsistenz nahezu unverändert ist; dies bedeutet insbesondere, daß die Viskosität der Emulsionen auf Basis der erfindungsgemäßen Emulgatorkonzentrate im Laufe der Lagerung annähernd konstant bleibt.The emulsifier concentrates according to the invention can advantageously be used for the production of cosmetic or pharmaceutical preparations. They are particularly suitable for the preparation of preparations in the form of emulsions, preferably of the water-in-oil type. The cosmetic or pharmaceutical emulsions produced on the basis of the emulsifier concentrates according to the invention are distinguished in particular by good storage stability. Storage stability means that after several months of storage the emulsions show no signs of separation or creaming and that the consistency is almost unchanged; This means in particular that the viscosity of the emulsions based on the emulsifier concentrates according to the invention remains approximately constant in the course of storage.
