Bleach compositions containing metal bleach catalyst, and bleach activators and/or organic percarboxylic acids

Abstract

Laundry or cleaning composition comprising: (a) an effective amount, preferably from about 0.0001 % to about 99.9 %, more typically from about 0.1 % to about 25 %, of a bleach activator and / or organic percarboxylic acid; (b) a catalytically effective amount, preferably from about 1 ppb to about 99.9 %, of a transition-metal bleach catalyst which is a complex of a transition-metal and a cross-bridged macropolycyclic ligand; and (c) at least about 0.1 % of one or more laundry or cleaning adjunct materials, preferably comprising an oxygen bleaching agent. Preferred compositions are laundry compositions and automatic dishwashing detergents which provide enhanced cleaning / bleaching benefits through the use of such catalysts in combination with bleach activators and / or organic percarboxylic acids.

Description

field of invention

[0001] The present invention relates to detergent and detergent additive compositions and methods of their use. The composition comprises selected transition metals such as Mn, Fe or Cr with selected large polycyclic rigid ligands, preferably cross-linked large polycyclic ligands with bleach activators and / or organic percarboxylic acids, Combinations of hydrophobic and / or hydrophilic bleach activators are preferred. More particularly, the present invention relates to the catalytic oxidation of soils and stains and the inhibition of dye transfer during laundering of fabrics, said soils and stains using cleaning compositions comprising bleach activators and / or organic percarboxylic acids and said metal catalysts. For example on surfaces such as fabrics, dishware, counter tops, dentures, etc. The composition comprises a bleach activator and / or an organic percarboxylic acid, a detergent adjunct component and a catalyst, wherein the catalyst comprises a combina...
