PROBLEM TO BE SOLVED: To provide an aerosol composition partially converted to a foamed viscous liquid or a paste when discharged on the skin, etc., foaming slowly thereafter to spontaneously generate large spit-spat noise by bubble breakage and larger spit-spat bubble-breaking noise when shearing force is applied to the extruded material with finger tips or palm to give the bubble-breaking noise and the comfortable feeling caused by the bubble breakage, and continuing the bubble-breaking effect over a long time.SOLUTION: The aerosol composition is composed of a stock solution containing an oily base, a water-soluble polymer, a surfactant and water and a liquefied gas, wherein the IOB value (inorganic/organic balance) of the oily base is 0.2-0.5, the amount of the oily base is 3-30 wt.% in the stock solution and the compounding ratio of the stock solution to the liquefied gas is 50/50 to 10/90.COPYRIGHT: (C)2009,JPO&INPIT【課題】皮膚などに吐出すると一部が発泡した粘稠液やペースト状となり、その後徐々に発泡して自発的にパチパチと大きな破泡音を発し、この吐出物に指先や手のひらなどでせん断を加えた場合には、さらに大きくパチパチと破泡音を発し、破泡時の音と泡のはじけによる心地よい感触が得られ、かつ、これら破泡効果が長時間持続するエアゾール組成物を開発する。【解決手段】油性基剤、水溶性高分子、界面活性剤、水とを含有する原液と、液化ガスとからなり、前記油性基剤のIOB値(無機性/有機性バランス)が0.2~0.5、油性基剤の配合量が原液中3~30重量%であり、原液と液化ガスの配合比が50/50~10/90(重量比)であるエアゾール組成物。【選択図】なし
