First Claim
Patent Images
1. 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 R3, when present, is selected from C1 -C12 alkyl and C6 -C12 aryl and wherein L, L'"'"' and L" are leaving groups;
L'"'"' being selected from the group consisting of ##STR31## wherein R4 is selected from --CO2 R5 and --OR5 wherein R5 is selected from C1 -C12 alkyl;
L and L" being selected from the group consisting of ##STR32## wherein R4 is selected from --CO2 R5 and --OR5 wherein R5 is selected from C1 -C12 alkyl;
Y is selected from --(SO3-)M, --(C(O)O)- M, --(C(O)OR6), --(SO42-)M, --(NR6)3)+ X, --NO2, --OH, O N(R6)2 and mixtures thereof;
X- is an oxidation compatible anion;
M is selected from sodium, potassium and ammonium;
R6 and R7 are selected from C1 -C12 alkyl and hydrogen;
R8 is selected from C1 -C12 alkyl;
each R1 is independently selected from the group consisting of alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, alkaryl, aryl, phenyl, hydroxyalkyl, and polyoxyalkylene;
each R2 is independently selected from alkylene, cycloalkylene, alkylenephenylene, phenylene, arylene, alkoxyalkylene, polyalkoxy-alkylene, and hydroxyalkylene, any R2 being substituted with a moiety selected from H, C1 -C20 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.
