PURPOSE:To obtain the title composition which needs only immersion to exhibit a cleansing effect without the necessity for any mechanical force by using a specified acidic substance and an alkaline substance which react with each other to foam and an active detergent component as constituents. CONSTITUTION:The title composition comprises an active detergent component, acidic particles which have a mean particle diameter (A) of preferably 300-1000mum, and contain an acidic substance (e.g. boric acid), and alkaline particles which have a mean particle diameter (B) and contain an alkaline substance (e.g. NaHCO3), wherein said acidic particles and alkaline particles react with each other to foam, A is greater than B by 100-500mum, the total amount of said acidic substance and alkaline substance is preferably 10-40wt.% based on the composition, and the pH of the composition when diluted 150-fold is 5.0 to 9.0. |
