Detergent compositions |
(57) There is provided a detergent composition containing:
(a) a source of peroxide compounds
(b) a peroxyacid bleach precursor composition comprising
i) an organic peroxyacid bleach precursor compound,
ii) an H₂O₂ scavenging material,
wherein said organic peroxyacid bleach precursor compound and said H₂O₂ scavenging
material are in close physical proximity within said composition.
The composition is useful in the bleaching of stains from stained coloured fabrics.
The H₂O₂ scavenging material acts to inhibit 'patchy' fabric discolouration to said
fabrics during the stain bleaching process.
