Abstract
Abstract Hydrophilic cotelomers having a terminal sulphonate group, and having the formula: ##STR1## wherein R 1 , R 2 , R 3 and R 4 are each independently H or C 1-4 alkyl; M is H or an alkali metal; M' is an alkali metal; 8≦a≦40 and 1≦b≦20. These cotelomers may also contain one or more of the following structural units, A; ##STR2## wherein R 3 , R 4 , R 5 and R 6 are each independently H or C 1-4 alkyl; R 7 is C 1-8 alkyl; R 8 and R 9 are each independently H or C 1-2 alkyl; Y is aryl; M is H or an alkali metal; Z is M or C 1-8 alkyl; 0≦c≦2; 0≦d≦3; 0≦e≦2; and 0≦f≦10. Detergent powders containing from 10 to 50% by weight of these hydrophilic cotelomers instead of sodium tripolyphosphate have good detergent and anti-redeposition powers.
