ABSTRACT:
A process of stabilizing bleaching agents in a detergent composition using a nonphosphorus-containing biodegradable stabilizer. The process involves incorporating into a detergent composition containing a bleaching agent, a biodegradable compound of the formula ##STR1## in which m is NR' or sulfur; X is SO.sub.3 H or COOH; Y is hydrogen, SO.sub.3 H or COOH; R and R' are, independently, hydrogen, --CH(Z)CH.sub.2 (Z'), --CH(Z)CH(Z')(Z") or --CH.sub.2 COOH; and Z, Z' and Z" are, independently, hydrogen, OH, SO.sub.3 H or COOH; or a sodium, potassium or ammonium salt thereof, in an amount sufficient to stabilize the bleaching agent. Novel detergent compositions containing the biodegradable bleach stabilizers are also disclosed.
