Abstract

The present invention relates to a photo bleaching compositions comprising:

A) from 0.5 ppm by weight, of a photo bleaching agent, said agent comprising:

a) a polymeric component, said polymeric component comprising one or more polymeric compounds having an average molecular weight of from 500 to 1,000,000 wherein at least 50% of the monomers which comprise said polymeric compounds comprise one or more di-polar, aprotic groups and have a polymerizable vinyl moiety, the balance comprising monomers selected from the group consisting of acrylic acid, acrylic acid esters, acrylic acid amides, methacrylic acid, methacrylic acid esters, methacrylic acid amides, and mixtures thereof; and

b) a photo bleaching component, said photobleaching component comprising a porphyrin or a phthalocyanine ring wherein said phthalocyanine ring can optionally be substituted at one or more ring positions, and said ring comprising a transition metal or cation having an oxidation state of two or greater;

wherein said photo bleaching component is integrated with said polymeric component to form said photo bleaching agent and the weight ratio of polymeric component (a) to photobleaching component (b) is from 1:1 to 1000:1;

B) from 0.1% by weight, of a peroxy acid bleaching compound precursor; and

C) the balance carriers and adjunct ingredients.
