Laundry treatment compositions, especially detergent compositions or rinse conditioners, which deposit cellulosic polymers or related polysaccharide fabric rebuild agents onto textile fabrics are described. Such agents are used for laundering cellulosic fabrics such as cotton, to compensate for gradual loss of fibrous material on repeated washing. Preferred rebuild agents are cellulose monoacetate, cellulose hemisuccinate and other cellulose esters.
A water-soluble or water-dispersible material for deposition onto a substrate during a treatment process, the material comprising: (i) a deposition enhancing part having a polymeric backbone; and (ii) a benefit agent attached to the deposition enhancing part by a hydrolytically stable bond; The material undergoes during the treatment process, a chemical change which does not involve the hydrolytically stable bond and by which change the affinity of the material onto the substrate is increased.
A composition comprising a silicone and a substituted polysaccharide comprising .beta..sub.1-4 linkages having covalently bonded on the polysaccharide moiety thereof, at least one deposition enhancing group which undergoes a chemical change in water at a use temperature to increase the affinity of the substituted polysaccharide to a substrate, the substituted polysaccharide further comprising one or more independently selected silicone chains.
A method of reducing dye loss during the laundry treatment of dyed fabrics using a laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the material undergoes during the treatment process, a chemical change by which change the affinity of the material for the fabric is increased.
The invention relates to polysaccharide graft polymers useful for incorporation as benefit agents in laundry detergent and fabric treatment compositions, and their preparation. The invention also relates to substituted polysaccharides useful as macroinitiator intermediates for the preparation of the polysaccharide graft polymers, and the preparation of the macroinitiators. The polysaccharide graft polymers may be used, for example, to impart soil release and/or fabric care benefits to laundry detergent or fabric treatment compositions.
A method of conferring one or more benefits during the laundering of textile fabrics is disclosed. The method includes contacting the fabric with a modified naturally occurring polysaccharide gum having .beta.1-4 linkages, and a weight average molecular weight of 250,000 or less.
