BUILDER COMPOSITION WITHOUT ZEOLITES OR PHOSTATES COMPRISING A SYSTEM REDUCING CALCIUM INCRUSTATIONS, ITS USE IN DETERGENT COMPOSITIONS AND DETERGENT COMPOSITIONS

摘要

Detergent builder composition comprising a fully soluble zeolite and phosphate-free builder composition containing cogranulates comprising an alkali metal carbonate; an alkali metal silicate nSiO2-M2O, wherein M is an alkali metal, the SiO2-M2O molar ratio = n being 1.5-3.5; and silicate-bound water, the weight ratio (silicate-bound water)/(dry silicate) being greater than 33:100. The detergent builder composition also comprises an anti-incrustation system comprising a phosphonate or a mixture of organic phosphonates in an amount wherein the weight ratio of phosphate to carbonate is 0.007-0.05. The invention also concerns the use of said detergent builder composition in association with at least one detergent in washing machine detergent compositions, and also these washing compositions.
