A method of treating coloured fabrics with a luminance (L*) less than 50, preferably black garments, which comprises contacting the fabrics with a wash liquor comprising 0.001-0.1 g/L of a hydroxyl C2-C4 alkyl derivative of a beta 1-4 polysaccharide, which is preferably hydroxyethyl cellulose, and a surfactant.

Method of laundering coloured fabrics

The present invention provides a laundry bleaching composition comprising: a) a macrocycilc tetra amido N-donor metal-ligand complex (preferably, 5,6-benzo-3,8,11,13-tetraoxo-2,2,9,9,12,12-hexamethyl-1,4,7,10-tetraaza-cyclo-tridecane), and b) an alkyl benzene sulphonate surfactant, said composition being substantially devoid of any added peroxygen bleach or a peroxy-based or peroxy-generating bleach system.

Composition comprising macrocyclic tetra-amido metal complex as bleaching catalyst

A detergent composition having excellent color care properties when used to launder colored fabnrics. The composition comprises a dye transfer inhibiting polymer comprising one or more monomeric units containing at least one .dbd.N--C(.dbd.O) with the proviso that the dye transfer inhibiting agent does not comprise an -oxide group and a water soluble sunscreen.
