Abstract (en)

[origin: WO2009153184A1] 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. The composition may further comprise one or more of and preferably combinations of lipase, polyethyleneimine, a blue violet dye, preferably with an optical adsorption peak in the range 540-600nm, a fluorescer, a dye transfer inhibition polymer, a polycarboxylate anti-redeposition agent, a soil release polymer and a perfume (preferably encapsulated).
