Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
A bleaching composition consisting essentially of a water soluble peroxygen bleaching compound selected from the group consisting of perborates, percarbonates, persulfates, persilicates, perphosphates, hydrogen peroxide and sodium peroxide; and a water soluble imide having the formula R 1 --COOR wherein R represents a C 1 to C 4 alkyl or phenyl and R 1 represents an acyclic imide radical, an imide nitrogen atom of which is bonded directly to the depicted --COOR moiety, the mol ratio of imide to peroxygen compound ranging from 0.01 to 2.0.
Claim 2
Dependent Claim
86 words
A bleaching composition consisting essentially of a water soluble peroxygen bleaching compound selected from the group consisting of perborates, percarbonates, persulfates, persilicates, perphosphates, hydrogen peroxide and sodium peroxide; and a water soluble imide having the formula R 1 --COOR wherein R represents a C 1 to C 4 alkyl or phenyl and R 1 represents an acyclic imide radical, an imide nitrogen atom of which is bonded directly to the depicted --COOR moiety, the mol ratio of imide to peroxygen compound ranging from 0.01 to 2.0.
