Abstract:
An aqueous aerosol or foam hair styling composition comprising:(a) from 1 to 15 weight percent of at least one acrylic hair fixative resin, based on total weight of the aqueous aerosol or foam hair styling composition, wherein the acrylic hair fixative resin comprises as polymerized units from 5 to 95 weight percent of at least one (C1-C12)alkyl (meth)acrylate, and from 2 to 50 weight percent of at least one C3-C8 monoethylenically unsaturated monocarboxylic acid monomer, based on total weight of the acrylic hair fixative resin; (b) from 10 to 70 weight percent of at least one propellant, based on total weight of the aqueous hair styling composition; and (c) from 0.1 to 2 weight percent of a phosphate ester emulsifier selected from the group consisting of (C8-C18)alkylaryloxypoly(alkyleneoxide) monoesters of phosphoric acid, (C8-C18)alkylaryloxypoly(alkyleneoxide)diesters of phosphoric acid, (C10-C18)alkyloxypoly(alkyleneoxide) monoesters of phosphoric acid, (C10-C18)alkyloxypoly(alkyleneoxide)diesters of phosphoric acid, salts thereof, and mixtures thereof, based on total weight of hair fixative resin; wherein the hair fixative resin is an emulsion polymer prepared in the absence of sulfate or sulfonate emulsifiers and in the presence of said phosphate ester emulsifier and wherein the composition has a pH from 6 to 9.5.
