摘要： A detergent builder composition including (A) at least 60 wt % of a mixture of at least one alkali metal carbonate and at least one alkali metal silicate nSiO2-M2O, where M is an alkali metal and the molar ratio SiO2/M2O is 1.5-3.5 while the weight ratio of the alkali metal silicate to the alkali metal carbonate is of 5:95-45:55; (B) 0.5-5 wt % of linear sodium polymetaphosphate of formula (NaPO3)m, where m is 10-30, optionally mixed with an organic phosphonate; and (C) optionally up to around 35 wt % of an N-carboxymethylated glutamic acid derivative or a water-soluble salt thereof, optionally mixed with a polymer or copolymer derived from an acrylic monomer, is disclosed. The use of said detergent builder composition in combination with at least one detergent in detergent compositions, as well as washing compositions with a low calcium scaling level, are also disclosed.
