Abstract
The present invention provides a prewashing treatment composition for clothes ensuring that superb washing ability is obtained by washing after it is applied to materials to be washed. The prewashing treatment composition comprises (a) a surfactant, (b) a chelating agent having a specified calcium-chelating capacity and a specified stability constant of calcium complex and a molecular weight of 1000 or less, (c) water and (d) an alkali agent in each specified ratio, and has a pH of 7.5 to 12 at 20° C.
Claims10
A prewashing treatment composition for clothes, comprising:
- (a) 0.05 to 10 mass % of a surfactant;
- (b) 1 to 30 mass % of a chelating agent having a calcium-chelating capacity of 200 to 600 CaCO3 mg/g, a stability constant of calcium complex of 4 to 10 and a molecular weight of 1000 or less;
- (c) 50 to 95 mass % of water;
- and (d) 1 to 30 mass % of an alkali agent, and having a pH of 7.5 to 12 when measured at 20° C.
