Patent number: 6335313Abstract: In the detergent granules including 10% by weight or more of a nonionic surfactant and 1% by weight or more of a crystalline alkali metal silicate having an average particle size of from 1 to 60 &mgr;m, the detergent granules characterized in that a proportion of the nonionic surfactant to the crystalline alkali metal silicate is in a weight ratio of from 20/1 to 1/20, and that the iron content calculated as Fe in the crystalline alkali metal silicate is 140 ppm or less. The granular detergent composition characterized in that the granular detergent composition includes the detergent granules described above.Type: GrantFiled: April 28, 1998Date of Patent: January 1, 2002Assignee: Kao CorporationInventors: Katsuhiko Kasai, Shu Yamaguchi, Hitoshi Takaya, Taiji Nakamae, Itsuro Tsukahara
