Abstract
A process of bleaching using at least one imide-aromatic (poly)peroxyacid, having a formula: ##STR1## wherein A represents the residue of a benzene or napthalene ring optionally substituted by a COOH or COOOH group, the symbol or symbols R, which may be the same or different from each other, represent a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group, an OH group, a COOH group, a COOOH group, a COOR' group, wherein R' represents a C.sub.1 -C.sub.5 alkyl group, or a substituted C.sub.1 -C.sub.5 alkyl group wherein the substituent is nitro, an OH group or a C.sub.1 -C.sub.5 alkoxy group, and n is an integer from 1 to 5.
Claims2
A method for bleaching comprising applying a bleaching agent to textiles, wherein the bleaching agent is capable of being effectively operated at temperature between about 20.degree. and 90.degree., said bleaching agent being an imide-aromatic (poly)peroxycarboxylic acid having the formula:
- ##STR3## wherein A represents the residue of a benzene or napthalene ring optionally substituted by a COOH or COOOH group, the symbol or symbols R, which may be the same or different from each other, represent a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group, an OH group, a COOH group, a COOOH group, a COOR' group, wherein R' represents a C.sub.1 -C.sub.5 alkyl group, or a substituted C.sub.1 -C.sub.5 alkyl group wherein the substituent is nitro, an OH group or a C.sub.1 -C.sub.5 alkoxy group, and n is an integer from 1 to 5.
In a method of treating fabrics comprising treating said fabrics with a bleaching agent used alone or in a liquid or solid detergent formulation containing other components and/or additives selected from the group consisting of builders, surfactants, soaps, zeolites, hydrotropic agents, corrosion inhibitors, enzymes, optical bleaching agents, stabilizers and other peroxydic compounds;
- the improvement wherein the bleaching agent is capable of being effectively operated at a temperature between 20.degree. and 90.degree. C., and said bleaching agent is an imide-aromatic (poly)peroxycarboxylic acid having the formula:
- ##STR4## wherein A represents the residue of a benzene or napthalene ring optionally substituted by a COOH or COOOH group, the symbol or symbols R, which may be the same or different from each other, represent a hydrogen atom, a C.sub.1 -C.sub.5 alkyl group, an OH group, a COOH group, a COOOH group, a COOR' group, wherein R' represents a C.sub.1 -C.sub.5 alkyl group, or a substituted C.sub.1 -C.sub.5 alkyl group wherein the substituent is nitro, an OH group or a C.sub.1 -C.sub.5 alkoxy group, and n is an integer from 1 to 5.
