摘要：
An aqueous post-foaming composition comprising (i) 2-20% wt of anionic surfactant(s), (ii) 1-10% wt of amine oxide surfactant(s), (iii) 0.5-3% wt of a hydrophobically modified alkali-swellable acrylic emulsion (HASE) polymer, as polymer solids and (iv) a foaming agent comprising a non-polar saturated aliphatic hydrocarbon having 3-6 carbon atoms, wherein the composition is capable of suspending water insoluble solid particles or liquid droplets. The HASE polymer may be an acrylate/steareth-20 methacrylate copolymer, an acrylate/beheneth-25 methacrylate copolymer or an acrylate/palmeth-25 acrylate crosspolymer, preferably at an amount of 1-2% by weight. A preferred anionic surfactant is sodium laureth sulphate (SLES), 5-15% wt, and preferred amine oxide surfactants are lauramine oxide, myristamine oxide, cocamine oxide, lauramidopropyl amine oxide, myristamidopropyl amine oxide and cocamidopropyl amine oxide, at an amount of 1-5% wt. The foaming agent may be n-butane, isobutane, n-pentane, isopentane or neopentane, at an amount of 2-20% wt. The composition may be packaged in an aerosol container. It is in gel or cream form and it may be used as a body, facial or hand wash, for washing hair or as a shaving gel. It may also serve as a vehicle for the delivery of various ingredients to the skin or hair.
