PROBLEM TO BE SOLVED: To provide a solid foaming bath agent composition efficiently dissolving carbon dioxide gas in bath water by adjusting the foaming behavior of the bath agent, suppressing its floating on a warm water surface and increasing the ratio (in-water foaming time)/(total dissolution time).SOLUTION: This solid foaming bath agent includes the following components (A) to (C) and used by an amount so as to make the concentration of the component (A) in bath water become 0.0008 to 4 ppm. (A) is a 0.01 to 0.5 mass% nonionic surfactant having &ge2 and <6 HLB, (B) is an organic acid, and (C) is a carbonate.COPYRIGHT: (C)2011,JPO&INPIT【課題】浴用剤の発泡挙動を調節し、湯面への浮上を抑制し、水中発泡時間/全溶解時間を高めることにより、炭酸ガスを浴水中に効率的に溶解せしめることが可能な固形発泡浴用剤組成物を提供する。【解決手段】次の成分(A)~(C)を含有し、当該成分(A)の浴水中の濃度が0.0008~4ppmになる量使用される固形発泡浴用剤組成物。(A)HLB2以上6未満の非イオン界面活性剤:0.01~0.5質量%(B)有機酸(C)炭酸塩【選択図】図1
