PURPOSE:To provide the title high-quality composition containing, as the main active ingredient, an alpha-sulfofatty acid alkyl ester or its water-soluble salt. CONSTITUTION:A water-base slurry with a pH of <=10 containing (A) an alpha- sulfofatty acid alkyl ester or its water-soluble salt, (B) zeolite, and (C) sodium sulfate at the weight ratios A/B=(1:0.5)-(1:5) and A/C=(1:0.3)-(1:3) with the ingredients A, B and C accounting for >=70wt.% of the total solid content, is put to spray drying. The resulting dry powder is kneaded under pressurized densification in a kneader together with an alkali builder and a binder component, and the resulting densified form is ground and granulated, thus obtaining the objective composition. |
