Abstract:
A bleaching detergent composition in a form of granules or powders containing an organic peracid precursor which produces an organic peracid upon reaction with hydrogen peroxide in water, the organic peracid having an alkyl group with 7 to 19 carbon atoms, and a hydrogen peroxide releasing material, wherein the bleaching detergent composition comprises the following components a) to c):a) one or more surfactants, including at least one nonionic surfactant;b) one or more crystalline alkali metal silicates having an SiO.sub.2 /M.sub.2 O ratio of from 0.5 to 2.6, wherein M is an alkali metal atom; andc) one or more agents for capturing metal ions other than the crystalline alkali metal silicates b), wherein a total amount of the above a), b), and c) components in the bleaching detergent composition occupies from 70 to 99% by weight, and wherein the weight ratio of component b) to component a) is b/a=90/10 to 45/55, and the weight ratio of component b) to component c) is b/c=7/93 to 75/25, and wherein the weight ratio of the organic peracid precursor to said at least one nonionic surfactant in component a) is from 15/85 to 50/50, and wherein the amount of said at least one nonionic surfactant is 70 to 100 % by weight of the entire surfactant component a).
