The present invention describes high content glycerol liquid compositions comprising N-acyl amino acids and/or salts and defined sulfosuccinic acid monoesters. Although large amounts of glycerin normally destabilizes such compositions, inclusion of dialkylene glycol has been found to enhance stability. A method of enhancing stability of high content glycerin compositions comprising N-acyl amino acids or salts thereof and sulfosuccinic acid monoesters is also described.
La présente invention concerne des compostions liquides à forte teneur en glycérol contenant N-acyl aminoacides et/ou leurs sels ainsi que des monoesters d'acide sulfo-succinique définis. Bien que de grandes quantités de glycérine déstabilisent normalement ces compostions, on a constaté que l'ajout de dialkylène glycol renforce la stabilité. En outre, cette invention concerne un procédé d'augmentation de la stabilité des compositions à forte teneur en glycérine contenant N-acyl aminoacides ou leurs sels, ainsi que des monoesters d'acide sulfo-succinique.
