PROBLEM TO BE SOLVED: To provide nonionic surfactant-containing particles whose adhesion to a granulator is inhibited, when produced, and which does not cause caking, even when preserved at high temperature and at high humidity, and prevents the hydrolysis of an ester structure-having nonionic surfactant component. SOLUTION: The nonionic surfactant-containing particles are characterized by comprising (a) a nonionic surfactant represented by the below-mentioned formula (I) in an amount of 10 to 40 wt.% based on the total weight of the particles, (b) water-soluble inorganic powder in an amount of 5 to 40 wt.%, (c) aluminosilicate powder in an amount of 20 to 60 wt.%, and (d) slightly water-soluble carbonate powder in an amount of 1 to 20 wt.%, wherein (d)/(c)≥5/95. R1CO(OX)nOR2 (I) [R1 is a 5 to 39C alkyl or alkenyl; R2 is a 1 to 4C alkyl or alkenyl; X is a 2 to 4C alkylene; (n) is a larger positive number than 0]. COPYRIGHT: (C)2007,JPO&INPIT
