Description

Verfahren zur Konservierung nichtionischer, kosmetischer und pharmazeutischer Emulsionen Die Erfindung bezieht sich auf ein Verfahren zur Konservierung nichtionischer, kosmetischer und pharmazeutischer Emulsionen, wie Salbengrundlagen u. ä. Sie besteht darin, daß als Konservierungsmittel Alkylester der Sorbinsäure verwendet werden.Process for the preservation of nonionic, cosmetic and pharmaceutical Emulsions The invention relates to a method for preserving nonionic, cosmetic and pharmaceutical emulsions, such as ointment bases and the like in that alkyl esters of sorbic acid are used as preservatives.

Es ist an sich bekannt, daß phenolische Konservierungsmittel, wie die bekannten, auch in der Lebensmittelindustrie zugelassenen p-Hydroxybenzoesäureester durch nichtionogene Emulgatoren vom Typ der polyoxäthylierten Fettsäureester weitgehend inaktiviert werden. Eine Inaktivierung der eingangs erwähnten phenolischen Konservierungsmittel tritt aber auch durch andere makromolekulare Verbindungen, wie Polyäthylenglykole, Polyvinylpyrrolidon, Methylcellulose, Gelatine usw., ein. Es ist daher ein Problem der einschlägigen Technik, kosmetische und pharmazeutische Zubereitungen mit einem Gehalt an nichtionogenen Emulgatoren oder anderen makromolekularen Verbindungen dauernd, sicher und im pH-Bereich über 7 gegen Schimmelpilz- und Bakterienbefall zu schützen. Die in der Lebensmitteltechnik vielfach als Konservierungsmittel noch benutzte Sorbinsäure ist bei Anwesenheit makromolekularer bzw. nichtionischer Emulgatoren nur im sauren Bereich wirksam, sie versagt aber bei der Konservierung von neutralen und alkalischen Emulsionen.It is known per se that phenolic preservatives such as the well-known p-hydroxybenzoic acid esters, also approved in the food industry largely by non-ionic emulsifiers of the polyoxyethylated fatty acid ester type be inactivated. Inactivation of the phenolic preservatives mentioned at the beginning but also occurs through other macromolecular compounds, such as polyethylene glycols, Polyvinyl pyrrolidone, methyl cellulose, gelatin, etc. It is therefore a problem the relevant technology, cosmetic and pharmaceutical preparations with one Content of non-ionic emulsifiers or other macromolecular compounds permanent, safe and in the pH range above 7 against mold and bacterial attack to protect. In food technology, they are still often used as preservatives The sorbic acid used is in the presence of macromolecular or nonionic emulsifiers only effective in the acidic range, but it fails to preserve neutral ones and alkaline emulsions.

Es war überraschend und darin besteht die Erfindung, daß sich kosmetische und pharmazeutische Zubereitungen, insbesondere Emulsionen durch Zusatz von 0,1 bis 1%, vorwiegend 0,3%, von Alkylestern der Sorbinsäure auch im neutralen und alkalischen pH-Bereich konservieren lassen.It was surprising and that is the invention that cosmetic and pharmaceutical preparations, especially emulsions with the addition of 0.1 up to 1%, predominantly 0.3%, of alkyl esters of sorbic acid, also in neutral and alkaline acids Allow the pH range to be preserved.

Die vorwiegend in Frage kommenden Äthyl-, Propyl- und Isopropylester der Sorbinsäure werden nach an und für sich bekannten Verfahren hergestellt und stellen wasserklare Flüssigkeiten mit einem angenehmen, leicht fruchtigen Geruch dar, der der erfindungsgemäßen Verwendung in keiner Weise entgegensteht.The predominantly suitable ethyl, propyl and isopropyl esters the sorbic acid are prepared and according to processes known per se represent water-clear liquids with a pleasant, slightly fruity smell represents, which in no way precludes the use according to the invention.
