PROBLEM TO BE SOLVED: To produce a foam which is dense and finely textured, easy to spread at an application site, and has less stickiness, and liquefied gas is generated even when the temperature rises in a state of being filled in an aerosol container. Provided is an effervescent aerosol composition that is difficult to separate, does not easily increase the internal pressure, and has excellent safety. SOLUTION: The stock solution containing an alkyl glucoside, an oil-soluble active ingredient and water, and a liquefied gas are contained, and the content of the oil-soluble active ingredient is 8 to 35% by mass in the stock solution, and the content of water is An effervescent aerosol composition which is 50 to 90% by mass in the undiluted solution. [Selection diagram] None【課題】濃密でキメが細かく、適用箇所において塗り伸ばしやすく、べたつきの少ない泡を作製することができ、かつ、エアゾール容器に充填された状態において、温度が上昇した場合であっても液化ガスが分離しにくく、内圧が上昇しにくく、安全性の優れた発泡性エアゾール組成物を提供する。【解決手段】アルキルグルコシドと油溶性有効成分と水を含む原液と、液化ガスとを含み、油溶性有効成分の含有量は、原液中、８～３５質量％であり、水の含有量は、原液中、５０～９０質量％である、発泡性エアゾール組成物。【選択図】なし
