Claims11
A detergent composition comprising:
- i) from about 0.1% to about 30% by weight of a bleach activator having the formula:
- ##STR28## wherein x is an integer from 2 to 4;
- each G is independently selected from the group consisting of ##STR29## provided that at least one G is ##STR30## and wherein R.sup.3, when present, is selected from C.sub.1 -C.sub.12 alkyl and C.sub.6 -C.sub.12 aryl and wherein L, L' and L" are leaving groups;
- L' being selected from the group consisting of ##STR31## wherein R.sup.4 is selected from --CO.sub.2 R.sub.5 and --OR.sup.5 wherein R.sup.5 is selected from C.sub.1 -C.sub.12 alkyl;
- L and L" being selected from the group consisting of ##STR32## wherein R4 is selected from --CO.sub.2 R.sup.5 and --OR.sup.5 wherein R.sup.5 is selected from C.sub.1 -C.sub.12 alkyl;
- Y is selected from --(SO.sub.3.sup.-)M, --(C(O)O).sup.- M, --(C(O)OR.sup.6), --(SO.sub.4.sup.2-)M, --(NR6)3).sup.+ X, --NO.sub.2, --OH, O N(R.sup.6).sub.2 and mixtures thereof;
- X.sup.- is an oxidation compatible anion;
- M is selected from sodium, potassium and ammonium;
- R.sup.6 and R.sup.7 are selected from C.sub.1 -C.sub.12 alkyl and hydrogen;
- R.sup.8 is selected from C.sub.1 -C.sub.12 alkyl;
- each R.sup.1 is independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, alkaryl, aryl, phenyl, hydroxyalkyl, and polyoxyalkylene;
- each R.sup.2 is independently selected from alkylene, cycloalkylene, alkylenephenylene, phenylene, arylene, alkoxyalkylene, polyalkoxy-alkylene, and hydroxyalkylene, any R.sup.2 being substituted with a moiety selected from H, C.sub.1 -C.sub.20 alkyl, alkenyl, aryl, aralkyl, and alkaryl;
- Z is an oxidation compatible ion;
- and j is selected such that said bleach activator is electrically neutral;
- and
- ii) from about 0.1% to about 70% by weight of a source of hydrogen peroxide.
