PROBLEM TO BE SOLVED: To provide a solid soap essentially consisting of a fatty acid soap having improved foamability and foam quality.SOLUTION: The fact that the foam quality of a solid soap is remarkably improved has been found. In a solid soap including a fatty acid soap by 20 to 70 mass%, dimethyl diallyl ammonium chloride/an acrylamide polymer and high polymerization polyethylene glycol are contained. Further, the solid soap contains a saccharide and polyol part by 30 to 70 mass%. The blending amount of ammonium dimethyl diallyl ammonium chloride/acrylamide polymer is 0.15 to 1.0 mass% to the whole quantity, the molecular weight of the high polymerization polyethylene glycol is 4,000,000 to 8,000,000, the blending amount thereof is 0.0005 to 0.002 mass% to the whole quantity of the solid soap.COPYRIGHT: (C)2016,JPO&INPIT【課題】起泡性及び泡質の改善した脂肪酸石鹸を主成分とする固形石鹸の提供。【解決手段】泡質が大きく改善されることを見出した。脂肪酸石鹸を20~70質量%含む固形石鹸において、塩化ジメチルジアリルアンモニウム/アクリルアミドポリマーと、高重合ポリエチレングリコールと、を含む固形石鹸。亦、更に糖・ポリオール部を30~70質量%を含む透明固形石鹸。塩化ジメチルジアリルアンモニウム/アクリルアミドポリマーの配合量は全量に対し0.15~1.0質量%であり、高重合度ポリエチレングリコールの分子量は400万~800万であり、その配合量は固形石鹸全量に対し0.0005~0.002質量%である固形石鹸。【選択図】なし
