Zusammenfassung: | An emulsifier combination free of ethoxylated emulsifiers and containing less than 20 wt.% water comprising an 8-14C alkyloligoglycoside (a); a polyolpolyhydroxystearate (b); and a 6-22C acyl glutamate (c), is new. An independent claim is also included for production of a nanoemulsion by stirring an aqueous phase containing component (c) and optionally further water-soluble components into an oil phase containing emulsifier components (a) and (b) and optionally further oil-soluble components and emulsifying the mixture.
Die Erfindung betrifft eine Emulgatorkombination, welche frei ist von ethoxylierten Emulgatoren, weniger als 20 Gew.-% Wasser enthält und C¶8¶-C¶14¶-Alkyloligoglucosid, Polyolpolyhydroxystearat und Acylglutamat umfasst. Die Emulgatorkombination eignet sich zur Herstellung von Nanoemulsionen in herkömmlichen Kalt/Kalt- oder Heiß/Heiß-Verfahren. Die Nanoemulsionen sowie ein Verfahren zu deren Herstellung sind ebenfalls Gegenstand der Erfindung. |
