Abstract
The present invention relates to the use of polymers comprising a block copolymer containing at least one group A and at least one group B in which each group A is a polymeric block built up from an ethylenically unsaturated polymerisable monomer and each group B is a polymeric block built up from an alkylene oxide, alkylene glycol or cyclic ether monomer or a mixture thereof for promoting soil release during laundering of a textile fabric and processes for their preparation. Laundry cleaning compositions comprising such polymers, a method of promoting soil release during laundering of a textile fabric and the use of such polymers in the manufacture of a laundry cleaning composition for effecting soil release from a laundry item form other aspects of the invention.
