Abstract:
An aerosol pressurized device comprising a pressurized receptacle, said receptacle containing a propellant gas and a foaming pressurizable oil-in-water emulsion comprising:(A) from 10 to 30% by weight of at least one cosmetic oil; (B) from 2 to 10% by weight of at least one non-ionic emulsifier having an HLB from 9 to 12, wherein said non-ionic emulsifier is: (i) an addition product of ethylene oxide and a fatty alcohol containing 6 to 30 carbons, or (ii) an addition product of ethylene oxide and a partial ester of a C3-C16 polyol and a C14-C22 fatty acid, (C) from 5 to 15% by weight of at least one anionic, cationic, non-ionic or amphoteric foaming surfactant, wherein said foaming surfactant is a polyglyceryl alkyl ether, an alkylglucoside, an alkylphosphate, an alkyl taurate, a sulphosuccinate, an alkyl sulfate, a sarcosinate, an alkyl ether sulphate, an isethionate, an alkyl ether carboxylate, an amine oxide, a quaternary ammonium salt, or a betaine, (D) from 40 to 60% by weight of water, wherein the oil phase of the oil-in-water emulsion comprises oil particles having a particle size ranging from 50 to 1000 nm, and the ratio of the weight of the oil to the weight of the foaming surfactant is greater than or equal to 1.
