  • Publication number: 20020052302
    Abstract: 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.

  • Patent number: 6358903
    Abstract: A laundry treatment composition comprising peroxygen bleach and a water-soluble or water dispersible rebuild agent for redeposition onto a fabric during the laundry process, wherein the fabric rebuild agent undergoes during the laundry process, a chemical change by which change the affinity of the material for the fabric is increased. The peroxygen bleach was found to increase the deposition of the fabric rebuild agent.

  • Publication number: 20020013248
    Abstract: A fabric rebuild polymer comprising a cellulose or other &bgr;-1,4 linked polysaccharide backbone with acetate groups pendant thereto, the average degree of substitution of acetate groups on the saccharide groups of the backbone being 0.55-0.70, with a molecular weight in the range 12,000-20,000 gives particularly effective fabric rebuild effect in a laundry treatment process at a pH in the range 9.5-11.0.

  • Publication number: 20010055574
    Abstract: A cosmetic composition is a structured emulsion of a continuous phase containing water-immiscible liquid carrier plus a structurant, and a disperse phase which is a solution of antiperspirant active in a more polar, probably aqueous, solvent. The structurant is a material which forms a network of fibers in the continuous phase, thereby gelling it. The structurant has an enthalpy of gelation in the carrier liquid or a test liquid with a magnitude of at least 30 kJ/mole. This minimum enthalpy of gelation facilitates processing at conveniently accessible temperatures and promotes stability.

  • Publication number: 20010039252
    Abstract: A fiber rebuild polymer comprising a cellulose or other &bgr;-1, 4 linked polysaccharide backbone with acetate groups pendant thereto, the average degree of substitution of acetate groups on the saccharide groups of the backbone being 0.55-0.70, is used to inhibit wrinkling and improve ironability of cloth during a laundry process.
