Abstract
A detergent composition adopted for the washing of a fibrous textile substrate, notably a textile substrate comprising fibers of a synthetic organic polymer, includes an anti-redepositon effective amount of at least one hydrophilic/hydrophobic anti-redeposition copolymer which comprises at least one of the recurring units ethylene oxide and alkylene oxide, said copolymer being such as to reduce the zeta potential of the fibers of said textile substrate to a value of 0.5 times or less the zeta potential of the bare fiber content thereof, and said effective amount being such that at least 0.02 mg of said copolymer is adsorbed onto said textile fibers per gram of substrate.
