The invention relates to compounds of general formula (I), ##STR00001##
in which each E independently represents O or NR.sup.1, with the proviso that at least 1 E is not O and at least 1 R.sup.1 represents a substituted C.sub.1-22 alkyl of the general formula (IIa) or (IIb) or (IIIa) or (IIIb), ##STR00002##
in which Q represents O or CH.sub.2, w represents a number from 1 to 22, q represents 1 or 2 and A.sup.+ represents a cation selected from alkali metal cations where q=1, ½ alkaline earth cations where q=2 and ammonium ions where q=1, as well as metal complexes having this ligand compound and dishwashing detergents which contain such metal complexes.

A process for washing fabrics including the steps; a) contacting fabrics to be washed and a wash liquor in the drum of an automatic washing machine; b) washing the fabrics in the wash liquor in an automatic washing machine process, where the automatic washing machine process includes at least a main wash step; where the wash liquor includes; i) between about 0.5 ppm and about 5 ppm acyl hydrazone bleach catalyst; ii) between about 10 ppm and about 2500 ppm non-soap surfactant; iii) between about 50 ppm and about 2500 ppm of a hydrogen peroxide source, and where the wash liquor has a pH between about 6 and about 9.

Water-soluble unit dose articles including a bleach catalyst and methods of their use.

Solid, concentrated, multi-use, stabilized peroxygen bleach compositions are disclosed. The solid compositions employ a C6-C18 fatty acid binding system for improving shelf stability of an activated bleach composition containing a peroxygen source and a bleach activating agent. Methods of formulating and methods of use are further provided.

Bleach catalyst detergent compositions are provided. The compositions are suitable for use with additional detergent and/or bleaching compositions while providing bleach catalysts within a detergent composition. The detergent compositions are free of anionic surfactant, are highly aqueous and have a pH of less than 6. Methods of use for cleaning are disclosed.

Provided is the use of a lanthanide metal complex as a bleaching catalyst. In particular, the lanthanide metal complex comprises a ligand which is an aromatic compound having at least one electron withdrawing substituent and at least one nucleophilic group. Provided is also a composition containing the lanthanide metal complex.
