Abstract

Cosmetic and dermatological emulsions having at least one aqueous phase, comprising(a) an effective amount of one or more interface-active substances, selected from the group consisting of alkyl glucosides, which are characterized by the structural formula  in which R is a branched or unbranched alkyl radical having from 4 to 24 carbon atoms,(b) where in at least one of the aqueous phases one or more electrolytes is present in dissolved form, the ionic strength of the aqueous phases in which the electrolyte(s) is/are present in dissolved form being at least 0.075 mol/l,(c) and where {overscore (DP)} is an average degree of glucosylation of up to 2.
