Detergent composition |
(57) 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.
