  • Patent number: 9150993
    Abstract: The invention provides a method of laundering fabric which uses a pourable liquid detergent composition comprising 10-40% wt of surfactant, essentially consisting of nonionic and/or anionic surfactant (typically less than 90% wt LAS and at least 10% wt of nonionic surfactant) in which 10-40% wt of surfactant preferably passes the Calcium Tolerance Test described in the patent. The composition comprises no more than 15% wt of soap, (present as a minority in wt % terms of the total surfactant). In the method, the composition is diluted by a factor of greater than 500 to obtain a wash liquor which comprises 0.8-0.05 g/l of surfactant, and, the wash liquor is contacted with fabrics.

  • Publication number: 20050282984
    Abstract: A water-soluble, triazine-based, non-dye, cellulose cross-linking agent that has a highly flexible linking group between at least two, mono-reactive cross-linking moieties and further hydrophilic or non-hydrophilic substituents.

  • Publication number: 20050282726
    Abstract: Excellent cross-linking benefits, to improve wrinkle recovery can be obtained in laundry treatment by use of a triazine-based, cellulose cross-linking agent that has a highly flexible linking group between at least two, mono-reactive cross-linking moieties and cellulose unreactive substituent groups. The linking group acts as a ‘spring’ whereas the two end groups bind chemically to cotton fibres.
