DETERGENT GRAINS AND GRANULAR DETERGENT COMPOSITION
摘要
Detergent grains containing at least 10 % by weight of a nonionic surfactant and at least 1 % by weight of a crystalline alkali metal silicate having an average particle diameter of from 1 to 60 mu m, wherein the ratio by weight of the surfactant to the alkali metal silicate is from 20/1 to 1/20 and the alkali metal silicate is contaminated with iron in an amount of 140 ppm or less in terms of Fe; and a granular detergent composition containing these detergent grains.
