Description
Verfahren zur Herstellung von wäßrige, niedere Alkohole enthaltenden gelartigen Massen durch Zusatz von Fettsäuren und Polyglykoläthern Es ist bekannt, daß niedere Alkohole (Athyl-, Methyl-, Isopropylalkohol u. a.) bzw. ihre wäßrigen Lösungen verschiedener Konzentration dadurch zu Gallerten oder Pasten verfestigt »geliert« werden können, daß höhere Alkohole von der Art des Cetylalkohols und höherer in ihnen in Gegenwart von schutzkolloidartig wirkenden Stoffen, z. B. Sulfaten solcher höheren Alkohole oder auch Alkyl-Aryl-Sulfonaten, unter Erwärmen gelöst werden, worauf sich beim Abkühlen die Lösung zu einer Gallerte verfestigt, geliert. Process for the preparation of aqueous, lower alcohols containing gel-like masses by adding fatty acids and polyglycol ethers It is known that lower alcohols (ethyl, methyl, isopropyl alcohol and others) or their aqueous This solidifies solutions of various concentrations to form jellies or pastes That higher alcohols of the type of cetyl alcohol and higher can be "gelled" in them in the presence of protective colloid-like substances such. B. sulfates such higher alcohols or alkyl aryl sulfonates can be dissolved with heating, whereupon, on cooling, the solution solidifies to form a jelly, gels.
Es ist weiter bekannt, daß auch Acetale und Ather solcher höheren Alkohole bzw. ihre Gemische mit den höheren Alkoholen mit oder ohne Beisein eines besonderen, schutzkolloidartig wirkenden Stoffes, z. B. eines Alkoholsulfates, die beschriebene Gelierung der niederen Alkohole bzw. ihrer Lösungen bewirken. It is also known that acetals and ethers of such higher Alcohols or their mixtures with the higher alcohols with or without the presence of one special, protective colloid-like substance, z. B. an alcohol sulfate, the cause described gelation of the lower alcohols or their solutions.
Es ist ferner bekannt, daß Ester, z. B. Stearylacetat, Arachylacetat u. a., einerseits die Konsistenz und Haltbarkeit derartiger Gallerten, insbesondere solcher aus hochprozentigen niederen Alkoholen, wesentlich verbessern, wenn sie den Gelierungsgemischen zugesetzt werden, daß sie aber andererseits auch allein die Gelierung von Alkohollösungen bewirken, wenn sie dafür zusammen mit einem schutzkolloidartig wirkenden Stoff verwendet werden. It is also known that esters, e.g. B. stearyl acetate, arachyl acetate inter alia, on the one hand the consistency and shelf life of such jellies, in particular those made from high-proof lower alcohols, improve significantly if they are added to the gelation mixtures, but on the other hand they can also be added on their own cause the gelation of alcohol solutions if they are used together with a protective colloid acting substance can be used.
Schließlich ist bekannt, daß dabei als schutzkolloidartig wirkende Stoffe an Stelle von Alkoholsulfaten oder/bzw. Alkyl-Aryl-Sulfonaten auch Alkyl- bzw. Finally, it is known that it acts as a protective colloid Substances instead of alcohol sulfates and / or. Alkyl aryl sulfonates also alkyl respectively.
Arylpolyglykoläther verwendet werden können.Aryl polyglycol ethers can be used.
Es wurde gefunden, daß wenn man höhere Fettsäuren wie Palmitin-, Stearin-, Arachin-, Behensäure im Verein mit Alkylpolyglykoläthern in niederen Alkoholen unter Erwärmen löst, diese Mischung beim Abkühlen zu einer festen gelartigen Masse erstarrt. It has been found that if one uses higher fatty acids such as palmitic, Stearic, arachidic and behenic acids in combination with alkyl polyglycol ethers in lower alcohols when heated, this mixture dissolves into a solid gel-like mass on cooling stiffens.
Dies ist überraschend, denn Alkylpolyglykoläther, mit einer C8- bis Cj2-Kette ergeben, zu etwa 40 O/<> in reinem Wasser gelöst, eine glasklare, feste Masse. This is surprising, because alkyl polyglycol ethers, with a C8 bis Cj2 chain, dissolved to about 40 O / <> in pure water, results in a crystal clear, solid mass.
Versucht man aber, diese »Wasserverfestigung« auf Lösungen von 40 und mehr l'/e Äthylalkohol zu übertragen, so führt dies zu keinem Erfolg. Alkoholische Lösungen lassen sich mit solchen Alkylpolyglykoläthern allein somit nicht verfestigen. Auch ein Zusatz von höheren Fettsäuren bedingt mit den genannten Polyglykoläthern keine Gelierung der Alkohollösung.But if you try to apply this "water solidification" to solutions of 40 and to transfer more l '/ e ethyl alcohol, this does not lead to success. Alcoholic Solutions cannot therefore be solidified with such alkyl polyglycol ethers alone. The polyglycol ethers mentioned also require the addition of higher fatty acids no gelation of the alcohol solution.
Nimmt man nun aber solche Alkylpolyglykoläther, deren Alkyl-Kohlenstoffatom-Kette etwa ebenso lang ist, wie die der zu verwendenden Fettsäure, also z. B. einen C18 H37-Polyglykoläther und dazu Stearin- oder Arachinsäure, so führt die Verwendung eines solchen Gemisches zur Gelierung der Alkohollösung. But if one takes such alkyl polyglycol ethers, their alkyl carbon atom chain is about as long as that of the fatty acid to be used, so z. B. a C18 H37 polyglycol ether and stearic or arachidic acid are used such a mixture to gel the alcohol solution.
Beispiel I 0,80 g Cl8-Polyglykoläther und 0,50 g Stearinsäure werden in 8 cm3 50°/oigem Alkohol unter Erwärmen gelöst. Beim Abkühlen erstarrt die Lösung zu einer homogenen Gelerte. Example I 0.80 g of Cl8 polyglycol ether and 0.50 g of stearic acid are used dissolved in 8 cm3 of 50% alcohol with warming. The solution solidifies on cooling a homogeneous gelatin.
Beispiel II 0,80 g C20-Polyglykoläther und 0,50 g Arachinsäure werden in 8 cm3 600/obigem Äthylalkohol unter Erwärmen gelöst. Beim Abkühlen erstarrt die Lösung bei etwa 400 C zu einer homogenen Gelerte. Example II 0.80 g of C20 polyglycol ether and 0.50 g of arachidic acid become dissolved in 8 cm3 600 / above ethyl alcohol with heating. When it cools down, it solidifies Solution at about 400 C to form a homogeneous gelatin.
Beispiel III 0,80 g C20-Polyglykoläther und 0,50 g Behensäure werden in 8 cm8 480/obigem Äthylalkohol unter Erwärmen gelöst. Beim Abkühlen erstarrt die Lösung bei 580 C zu einer homogenen Gelerte. Example III 0.80 g of C20 polyglycol ether and 0.50 g of behenic acid dissolved in 8 cm8 480 / above ethyl alcohol with heating. When it cools down, it solidifies Solution at 580 C to a homogeneous gelatin.
Natürlich können an Stelle von einer Fettsäure auch Fettsäuregemische, an Stelle eines einzigen Alkylpolyglykoläthers Gemische mehrerer treten. In sinngemäßer Abwandlung können auch andere niedere Alkohole, z. B. Methyl- oder Isopropylalkohol verfestigt werden. Die erhaltenen Produkte vertragen die verschiedensten Zusätze sowohl zum Zwecke einer eventuellen Konsistenzverbesserung, als auch zwecks Erzeugung von Präparaten besonderer kosmetischer, medizinischer oder insbesondere bactericider Wirkung. Of course, instead of a fatty acid, fatty acid mixtures, Instead of a single alkyl polyglycol ether, mixtures of several are used. In analogous Modification can also be other lower alcohols, e.g. B. methyl or isopropyl alcohol be solidified. The products obtained tolerate a wide variety of additives both for the purpose of a possible consistency improvement, as well as for the purpose of generation of preparations of particular cosmetic, medicinal or, in particular, bactericides Effect.
