05-21(7737)A HYDROXAMATE BLEACH STABILIZER ABSTRACT There are disclosed compositions comprising peroxygen containing bleach systems containing a bleach stabilizing amount of compound represented by the formula Image wherein R is selected from the group consisting of optionally substituted straight and branched chained alkyl C1-21, alkenyl C1-21, hydrogen, and optionally substituted phenyl groups, and -?R"-?R"-?-Z wherein each R" is independently selected from groups consisting of hydrogen, alkyl C1-21 and alkenyl C1-21, provided that the total number of carbons in both R" groups is not greater than 21, each X is independently selected from hydrogen and SO3 and Z is selected from the group consisting of hydroxy, alkoxy C1-5 and alkenoxy C1-5, -O-M+, -NR2''' wherein each R''' is independently selected from the group consisting of hydrogen, alkyl C1-5 or alkenyl C1-5, and R' is selected from the group consisting of hydrogen, optionally substituted straight and branched chained alkyl C1-21, alkenyl C1-21 and an optionally substituted phenyl group, provided only one of R and R' is hydrogen said stabilizer having a hydrophile-lipophile (HLB) balance within the same range as the HLB of said compounds wherein R is an unsubstituted C1-21 alkyl group and R' is hydrogen or an unsubstituted C1-6 alkyl group, M is selected from hydrogen and a non- interfering cation, and further provided that when M+ represents hydrogen and the composition contains a detergent active agent, the bleaching agent is selected from an inorganic peroxy compounds and bleach activator combination or an organic peroxy acid.
