Document Type and Number:
Japanese Patent JPS6015679
Kind Code:
B2
Abstract:
Fabric, particularly soiled fabrics containing calcium carbonate crystal growth poisons, may be washed in hard water to which has been added a detergent active material and an alkali metal carbonate if a secondary detergency builder is added after a defined critical state of the system is reached. The secondary builder may be a precipitating, sequestering or ion exchange builder, and is added in such an amount which would be insufficient, in the absence of the carbonate, to reduce the free calcium ion concentration to less than 10-5 molar. The delayed addition can be achieved by separate dosing, coating the secondary builder, dosing the composition in the form of a two-compartment sachet or forming the secondary builder material in situ. The composition may include a material, such as calcite, to promote the occurrance of the critical state.
