Abstract
Official abstract text for this publication.
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 540-600 nm, a fluorescer, a dye transfer inhibition polymer, a polycarboxylate anti-redeposition agent, a soil release polymer and a perfume (preferably encapsulated).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of laundering fabric which comprises the steps of: a) providing a pourable liquid detergent composition comprising at least 3 wt % to less than 9.5 wt % ethoxylated polyethyleneimine, 3 to 9 wt % of a soil release polymer selected from water soluble/miscible or dispersible polyesters and 10-40% wt of surfactant, essentially consisting of nonionic and/or anionic and/or zwitteronic surfactant, which 10-40% wt of surfactant preferably passes the…
