Abstract:
A method of improving perfume deposition onto fabrics in a laundry treatment process and/or improving retention of perfume on laundered fabrics, comprising using a laundry treatment composition comprising a perfume in an amount effective to confer a retained fragrance onto the laundered fabrics; and a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during the laundry treatment process wherein the rebuild agent undergoes during the laundry treatment process, a chemical change by which change the affinity of the rebuild agent for the fabric is increased, said chemical change resulting in the loss or modification of one or more groups covalently bonded to be pendant to a polymeric backbone of the rebuild agent via an ester linkage, the ester-linked group(s) being selected from monocarboxylic acid esters; and wherein the polymeric backbone of the rebuild agent comprises cellulose units or other &bgr;-1,4 linked polysaccharide units.
