Patent ID: 7481996

Claim:
An aerosol cosmetic composition containing, in a pressure container, a stock solution comprising the following components (A) to (D): (A) 0.5 to 10 wt. % of a hair styling polymer, (B) 1 to 25 wt. % of a solvent having at least 2 hydroxy groups, having a molecular weight of 62 or greater but not greater than 1000 and being in a liquid form at 30° C., (C) 0.1 to 20 wt. % of a nonionic surfactant having an HLB of from 2.8 to 20 and being in a liquid form at 30° C. which is at least one selected from the group consisting of oleic acid monoglyceride, palm kernel diethanolamide, caprylic acid monoglyceride, sorbitan monooleate, isostearyl glyceryl ether, sorbitan monolaurate, tetraoleic acid polyoxyethylene sorbit, tetraoleic acid polyoxyethylene sorbitol and polyoxyethylene (9) tridecyl ether, and (D) ethanol and/or water, and (E) a propellant, a weight ratio of said components (A)/(B) falling within a range of from 0.42 to 2.3 wherein said hair styling polymer is at least one selected from the group consisting of alkylacrylamide/acrylate/alkylaminoalkylacrylamide/polyethylene glycol methacrylate copolymers, alkylacrylamide/alkylaminoalkylacrylamide/polyethylene glycol methacrylate copolymers, (methacryloyloxyethylcarboxybetaine/alkyl methacrylate) copolymers, (acrylates/lauryl acrylate/stearyl acrylate/ethylamine oxide methacrylate) copolymers, (vinylamine/vinyl alcohol) copolymers, acrylic resin alkanolamine solution, acrylic acid/acrylamide/ethyl acrylate copolymers, alkyl acrylate/methacrylic acid/silicone copolymer solution, polyurethane-1, polyvinylcaprolactam, alkyl acrylate copolymers, (octylacrylamide/hydroxypropyl acrylate/butylaminoethyl methacrylate) copolymers, (alkyl acrylate/octylacrylamide) copolymers, (VA/crotonic acid/vinyl neodecanoate) copolymers, polyurethane-14·AMP-acrylates copolymers, polyquatanium-28,(vinyl methyl ether/ethyl maleate) copolymers, (PVP/vinylcaprolactam/DMAPA acrylate) copolymers), (isobutylene/ethylmaleimide/hydroxyethylmaleimide) copolymers, polyquaternium-55, and (vinylpyrrolidone/DMAPA acrylate) copolymers, wherein a viscosity of said stock solution of component (A) to (D) ranges from 1 to 12 mPa·s and wherein an average particle size of droplets formed upon spraying of said stock solution from a container is 10 μm or greater but not greater than 40 μm.
