PURPOSE: To obtain the subject composition having excellent solubility even after preserving for a long period under severe conditions or when washing at a high temperature by mixing a specific amorphous aluminosilicate and a specific fatty acid mixture into a nonionic surfactant. CONSTITUTION: This composition is composed of (A) 12-35wt.% of a nonionic surfactant (preferably, a polyoxyethylene alkylether type having an average carbon chain length of 11-14 and an average EO adding mol number of 4-9), (B) 10-40wt.% of an amorphous aluminosilicate having moisture content of 25-30wt.% when dried at 800 deg.C for 1 hour [preferably a compound of formula I (M' is Na or K; (x) is 0.7-2; (y) is 1.8-6; (w) is a positive number)], (C) 10-30wt.% of a crystalline aluminosilicate [preferably a compound of formula II (M' is an alkali metal; M" is an alkaline earth metal changeable with Ca; (x) is 0.7-1.5; (y) is 1.8-6; (w) is a positive number)] and (D) 0.1-5wt.% of a 10-20C saturated and/or unsaturated fatty acid mixture, where the total of the components B and C is <=50wt.%. |
