Abstract: An aqueous surfactant composition containing one or more alpha-sulfo fatty acid disalts (A) of the general formula (I), R1CH(SO3M1)COOM2??(I) in which the radical R1 is a linear or branched alkyl or alkenyl radical with 6 to 16 carbon atoms and the radicals M1 and M2—independently of one another—are selected from the group H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamine, one or more alkyl glycosides (B) of the general formula (II), R2O-[G]p??(I) in which R2 is an alkyl and/or alkenyl radical with 8 to 18 carbon atoms, G is a sugar radical with 5 or 6 carbon atoms and p is numbers between 1 and 10, and water are disclosed. The composition has excellent foaming ability and is suitable for use in cosmetic products.

Abstract: Disclosed is the use of (A) an ester of levulinic acid with a fatty alcohol as solubilizing agent for oil soluble organic UV filters (B).

Abstract: The present invention relates to an alkyl glycoside sulfomethylsuccinate having the formula R1-O-Sn-R2 wherein R1 is an alkyl radical having 6 to 30 carbon atoms, S is a monosaccharide moiety, and R2 is a sulfomethylsuccinate moiety. Furthermore the present invention relates to a process for making this alkyl glycoside sulfomethylsuccinate and to an alkyl glycoside itaconate which is a useful intermediate for use in this process. Furthermore the present invention relates to a cosmetic composition comprising the alkyl glycoside sulfomethylsuccinate and to the use of the alkyl glycoside sulfomethylsuccinate for improving the foam stability of a cosmetic composition.

Abstract: What is proposed is aqueous surfactant compositions comprising one or more alpha-sulfo fatty acid disalts (A) of the general formula (I), R1CH(SO3M1)COOM2 ??(I) in which the radical R1 is a linear or branched alkyl or alkenyl radical with 6 to 16 carbon atoms and the radicals M1 and M2—independently of one another—are selected from the group H, Li, Na, K, Ca/2, Mg/2, ammonium and alkanolamine, one or more alkyl glycosides (B) of the general formula (II), R2O-[G]p ??(I) in which R2 is an alkyl and/or alkenyl radical with 8 to 18 carbon atoms, G is a sugar radical with 5 or 6 carbon atoms and p is numbers between 1 and 10, and water, where specific limiting conditions are to be observed. These compositions have excellent foaming ability and are suitable for use in cosmetic products.
