POWDERY DETERGENT COMPOSITION IMPROVED IN SOLUBILITY AT LOW TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a powdery detergent composition capable of efficiently preventing production of detergent aggregate which occurs when washed under low-temperature water and in a state in which agitating force is insufficient and exhibiting excellent solubility during washing. SOLUTION: The powdery detergent composition comprises (P) a complex particles obtained by treating the surface of (A) surface active agent particles containing 10-40% surface active agent and having≥150μm average particle diameter with (B) aluminosilicate particles having <30μm average particle diameter and (C) particles containing≥50% organic substance, having <30μm average particle diameter and having≥50°contact angle and has 1.01-20 ratio of relative area intensity before and after pulverization of IR intensity derived from the organic substance to IR intensity derived from an aluminosilicate in aluminosilicate particles.
