A detergent composition especially suitable for washing coloured fabrics includes a polymer mixture comprising
a) an alkalimetal carboxymethyl cellulose;
b) a vinylpyrrolidone polymer such as PVP with a molecular weight of 40,000; and
c) a carboxylate polymer such as polyacrylate or maleic acid/acrylic acid copolymer.
The compositions optionally contain a peroxyacid bleach system. Improved colour care of fabrics is obtained compared with any one or two of these polymers.  
                            一种特别适用于洗涤有色织物的洗涤剂组合物包括一种聚合物混合物,其中包括
a) 烷基亚甲基
羧甲基纤维素;
b) 
乙烯基吡咯烷酮聚合物,如分子量为 40,000 的 PVP;以及
c) 
羧酸聚合物,如聚
丙烯酸酯或
马来酸/
丙烯酸共聚物。
组合物可选择含有过氧酸漂白系统。与上述任意一种或两种聚合物相比,可改善织物的护色效果。
