The present invention provides stable bleach activator granules comprising: PA0 a) a peroxygen bleach activator having the structure: ##STR1## wherein R is C.sub.1-20 branched or straight chain alkyl, alkoxylated alkyl, cycloalkyl, alkenyl, aryl, substituted aryl, alkylaryl; R' and R" are independently H, C.sub.1-4 alkyl, aryl; and L is a leaving group; PA0 b) a pliable binding material selected from materials having a melting completion temperature of greater than about 40.degree. C.; and, optionally, PA0 c) a filler material. These bleach activator granules are combined with a detergent base which contains an oxidant bleach to provide an activated oxidant detergent composition.
