Abstract
Bleaching compositions are provided that comprise peracid activators. The peracid activators are ester derivatives of a carboxylic acid where the oxygen is covalently bound through a polyhydroxy linking group to a leaving group that is displaceable in a peroxygen bleaching solution by perhydroxide anion. When the peracid activator is combined with a source of peroxygen in aqueous solution, then a stain removing peracid is formed. One embodiment of the peracid activator has the structure ##STR1## where R' is a branched or linear C.sub.4-12 alkyl, n is 1 to about 7, and L is a leaving group.
Claims5
A bleaching composition comprising:
- (a) a peracid activator having the structure ##STR23## where R" is R' ##STR24## and R' is C.sub.4-12 alkyl or alkoxylated alkyl, where X is a polyhydroxy derivative of the structure --OCH.sub.2 CH.sub.2 O!.sub.n or --OCH.sub.2 CHCH.sub.s O!.sub.n and n is 1 to about 7, and where L is a leaving group selected from the group consisting of:
- ##STR25## wherein Y and Z are individually H, SO.sub.3 M, CO.sub.2 M, SO.sub.4 M, OH, halo substituent, OR.sup.2, R.sup.3, NR.sub.3.sup.4 X, and mixtures thereof, wherein M is an alkali metal or alkaline earth metal counterion, R.sup.2 is C.sub.1-20 alkyl, R.sup.3 is C.sub.1-6 alkyl, R.sup.4 is C.sub.1-30 alkyl and X is a counterpart ion thereto, and Y and Z can be the same or different;
- (ii) halide;
- (iii) --ONR.sup.6, wherein R.sup.6 contains at least one carbon which is singly or doubly bonded directly to N;
- ##STR26## wherein R.sup.18 is C.sub.1-10 alkyl;
- and (v) mixtures thereof;
- and
- (b) a bleach-effective amount of a peroxygen source.
A peracid activator having the structure ##STR28## wherein R is a C.sub.4-12 linear or branched alkyl and M is an alkali metal or alkaline earth metal counterion.
