PROBLEM TO BE SOLVED: To provide a bubbling powder bathing agent composition which is excellent in a warming touch and in a carbon dioxide bubbling property, does not cause the collapse of granules even on transportation and the like in a production process, and is excellent in a granule strength capable of resisting to handling and in storage stability.SOLUTION: The bubbling powder bathing agent composition comprises: (A) 30 to 80 mass% of granules comprising an organic acid, an oily ingredient, a nonionic surfactant and a water-soluble binder and (B) 70 to 20 mass% of a carbonate. The organic acid is preferably fumaric acid, and the content of the water-soluble binder contained in the granules is 2 to 30 mass%.COPYRIGHT: (C)2011,JPO&INPIT【課題】温まり感と炭酸ガスの発泡性に優れた発泡性粉末入浴剤組成物であり、製造過程における輸送等においても顆粒が壊れず、ハンドリングに耐えうる顆粒の粒子強度及び保存安定性に優れる、発泡性粉末入浴剤組成物の提供。【解決手段】(A)有機酸、油性成分、非イオン界面活性剤、水溶性バインダーを含む造粒物30~80質量%と、(B)炭酸塩70~20質量%を含む、発泡性粉末入浴剤組成物。有機酸としては、フマール酸がこのましく用いられ、また粒物中に含まれる水溶性バインダーの含有量は2~30質量%が好ましい。【選択図】なし
