Abstract:
A method of maintaining or improving skin condition, the method comprising applying to skin a composition comprising:a) a lower alcohol and water in a weight ratio of about 35:65 to about 95:5; and b) a thickener system present in an amount of about 0.5% by weight to about 8% by weight, based on the total weight of the composition; wherein the thickener system comprises at least two solid emulsifiers, each in an amount of at least about 0.05% by weight, based on the total weight of the composition; wherein at least one emulsifier comprises: (i) at least one hydrophobic group selected from the group consisting of: (A) an alkyl group of at least 16 carbon atoms; (B) an alkenyl group of at least 16 carbon atoms; and (C) an aralkyl or an aralkenyl group of at least 20 carbon atoms; and (ii) at least one hydrophilic group selected from the group consisting of: (A) an amide group; (B) a short chain ester of a long chain alcohol or acid; (C) a polyglucoside group having 1-10 glucose units; (D) a polyglycerol ester group having 1-15 glycerol units; (E) a secondary amine group; (F) a tertiary amine group; (G) a quaternary amine group; (H) an anionic group; (I) a zwitterionic group; and (J) combinations of these groups; wherein the composition has a viscosity of at least about 4,000 centipoise at 23Â° C. in the absence of auxiliary thickeners.
