  • Fabric care composition
    Publication number: 20010034316
    Abstract: Fabric care compositions for application to a fabric comprise a fabric softening and/or conditioning compound and a polymer, which is capable of self cross-linking and/or reacting with cellulose. The polymer is present in the composition in an amount of from 0.002% to 0.45%, preferably from 0.005% to 0.010% by weight based on the weight of the fabric. The polymers and the compositions may be used to enhance the delivery of perfume to a fabric from a fabric care composition, which comprises a perfume, and/or to enhance the softening of fabric by a fabric care composition, which comprises a fabric softening and/or conditioning compound.

  • Fabric care composition
    Patent number: 6255271
    Abstract: A fabric care composition comprises an amine or amide-epichlorohydrin resin or derivative thereof, a silicone component and, optionally, a textile compatible carrier. The textile compatible carrier facilitates contact between the resin and a fabric. The composition is adapted for use in the rinse cycle of a laundering process and may be used, as part of such a process, in the treatment of fabric to reduce creasing of the fabric.
