Novel metal complexes of tripoadal ligands are useful as catalysts to enhance the action of peroxygen compounds in washing, cleaning and disinfecting processes.

Metal complexes of tripodal ligands

A process for preventing the redeposition of migrant dyes in a washing liquor by adding to each liter of the washing liquor, which comprises a peroxide-containing detergent, from 0.5 to 150 mg of one or more asymmetric manganese complexes of the salen type.

Process for treating textile materials

The present invention relates to novel manganese complexes of salen ligands and the use thereof as catalysts that enhance the action of peroxy compounds in washing, cleaning, and disinfecting processes.

Manganese complexes of salen ligands and the use thereof

The present invention provides a process for inhibiting the re-absorption of migrating dyes in the wash liquor, comprising introducing into a wash liquor containing a peroxide-containing detergent, from 0.5 to 150 mg per liter of wash liquor, of one or more manganese containing compounds.

Fabric care method

A washing and cleaning process which comprises adding to the corresponding liquor comprising a peroxide-containing washing and cleaning agent 1 to 500 millimoles per liter of liquor of one or more than one compound of the salene type.

Washing and cleaning process

The inventions is drawn to mixtures of manganese complexes and organic ligands which significantly improve the bleaching effect of hydrogen peroxide in washing liquours and prevent the reabsorption of migrating dyes in peroxide-containing washing liquors.
