PURPOSE:To obtain the title composition which enables immersion cleansing and has improved detergency for various contaminants by mixing a branched anionic surface active agent, two kinds of inorganic or organic electrolytes having specified ions as the counter ion, and a solid binder. CONSTITUTION:The title composition is obtained by mixing 5-40wt.% branched anionic surface active agent (A) (e.g. a sodium alkylbenzenesulfonate), an inorganic or organic electrolyte (B) having Na<+> or K<+> as the counter ion (e.g. Na2SO4), 0.5-30wt.% binder (C) which is solid at ordinary temperature (e.g. a polyethylene glycol having an average molecular weight of 6,000), and an inorganic or organic electrolyte (D) having Mg<2+> as the counter ion (e.g. MgSO4) in an amount sufficient to provide a weight ratio of C to D of (10 to 1):(1 to 5) so that the molar ratio of component A to the total of Na<+> and K<+> in the composition is 1/4 or less and the pH of the composition when diluted 150-fold is 5.0 to 9.0. |
