According to the present invention, a solidified detergent composition is provided. The solidified detergent composition is characterized by having a reduced-pressure dried substance obtained by reduced-pressure drying a solution of (a) a silicon-containing compound with the addition of (b) at least one of surfactant to the silicon-containing compound, or a reduced-pressure dried substance obtained by reduced-pressure drying a solution of (a) a silicon-containing compound and (b) at least one of surfactant added to the resultant reduced-pressure dried substance, the silicon-containing compound being represented by the following general formula (1):
(wherein R1 shows a hydrocarbon group having 6 or more carbon atom number, R2 and R3 show a lower hydrocarbon group which may be same or different each other, R4 shows a bivalent lower hydrocarbon group, R5, R6 and R7 show a lower alkyl group or lower alkoxy group which may be same or different each other, X shows a halogen ion or organic carbonyloxy ion) and the surfactant being selected from the group consisting of (b1) a cationic surfactant (but excluding the above silicon-containing compound) and (b2) a nonionic surfactant.
根据本发明,提供了一种固化洗涤剂组合物。该固化洗涤剂组合物的特点是:通过减压干燥(a)含硅化合物的溶液并在含硅化合物中添加(b)至少一种表面活性剂而得到的减压干燥物质,或通过减压干燥(a)含硅化合物的溶液并在所得减压干燥物质中添加(b)至少一种表面活性剂而得到的减压干燥物质,含硅化合物由以下通式(1)表示:
(其中 R1 表示具有 6 个或更多碳原子数的烃基,R2 和 R3 表示彼此相同或不同的低级烃基,R4 表示二价低级烃基,R5、R6 和 R7 表示彼此相同或不同的低级烷基或低级烷氧基,X 表示卤素离子或有机碳酰氧离子),表面活性剂选自(b1)阳离子表面活性剂(但不包括上述含硅化合物)和(b2)非离子表面活性剂组成的组。
