Claims16
A peroxygen bleach activator comprising a mixture of compounds of the general formula ##STR34## where R is a straight or branched chain alkyl or alkenyl containing from about 4 to about 14 carbon atoms, R.sup.1 is H, --CH.sub.3, --C.sub.2 H.sub.5 or --C.sub.3 H.sub.7, L is a leaving group the conjugate acid of which has a pKa of about 4 to about 30, and X.sup.1 is H, Cl, OCH.sub.3 or OC.sub.2 H.sub.5 such that the weight ratio of substituted compounds wherein X.sup.1 =OCH.sub.3 OC.sub.2 H.sub.5 or Cl to unsubstituted compounds wherein X.sup.1 =H is from about 1:9 to about 9:1.
