The effectiveness of hydrogen peroxide for bleaching and disinfecting at ambient to hand hot temperatures can be enhanced by reaction with a peracid generator (activator).
The present invention provides emulsions of enol ester activators in aqueous acidic solutions of hydrogen peroxide containing a water soluble emulsifier in at least 1 part per part by weight of activator.
Preferably sufficient emulsifier mixture thereof is present to enable the resultant emulsion to be clear demonstrating the presence of thermodynamically stable micellar structures.
In preferred compositions, the activator is selected from vinyl or isopropenyl or but-1-enyl or cyclohex-1-enyl acetate heptanoate, octanoate or benzoate and divinyl adipate or phthalate, and 1,5-diacetoxypenta-1,4-diene.
The compositions can be used as such or upon dilution with aqueous media and in conjunction with detergent compositions, and for cleaning and desinfecting absorbent or non-absorbent materials.
