Abstract

The invention relates to cosmetic and pharmaceutical creams in the form of an oil-in-water emulsion containing at least one polar oil as the oil component, said polar oil having an interfacial tension (&ggr;1) with water of less than 30 mN/m at 25° C., and at least one plant protein as the emulsifier, a 1 wt % aqueous solution of said plant protein having an interfacial tension (&ggr;2) with the oil component at 25° C. which is less than the interfacial tension &ggr;1 between oil and water. Protein or protein-containing meals consisting of oats, wheat or peas are preferred as emulsifiers, whilst the oil components preferably belong to the group of C8-C22 fatty acid esters of monovalent or polyvalent C2-C22 alkanol esters of monovalent or polyvalent C2-C6 hydroxycarboxylic acids.
