Abstract:
A hydroalcoholic 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 emulsifiers, wherein at least one of the emulsifiers is solid at ambient temperature and each is present 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 quatemnary 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.
