wherein R1 is a linear, branched or substimted C8-C18 alkyl, alkenyl, aryl, alkaryl, ether or glycityl ether moiety, R2 is a C1-C3 alkyl moiety, R3 and R4 can vary independently and are selected from hydrogen, methyl and ethyl, X is an anion, A is C1-C4 alkoxy and p is an integer in the range of from 2 to 30.

2. A composition according to Claim 1 wherein the peroxygen bleach is selected from the group consisting of perborate, percarbonate, perphosphate, persilicate or persulfate salts or a preformed peracid.

3. A composition according to either of Claims 1 or 2 wherein the bleach catalyst is a manganese or a cobalt-containing bleach catalyst.

4. A composition according to any of Claims 1 to 3 which is prepared by mixing the non-AQA surfactant and the AQA surfactant.

5. A composition according to any of Claims 1 to 4 wherein the non-AQA surfactant is an anionic surfactant.
