Invention Summary

The invention comprises, in one embodiment, a stable, liquid, substantially nonaqueous detergent comprising:

at least one imidoperacid with the structure ##STR2##

wherein R is C.sub.1-20 alkylene, R.sup.1 and R.sup.2 are individually H or C.sub.1-6 alkyl or alkenyl, or R.sup.1 and R.sup.2 join to form a heterocycle, said imidoperacid being solubilized in a liquid nonionic surfactant.

It is therefore an object of this invention to provide a phase stable liquid, substantially nonaqueous detergent with an imidoperacid solubilized in the nonaqueous phase thereof.

It is a further object of this invention to provide a liquid, substantially nonaqueous detergent containing a solubilized imidoperacid which has prolonged physical and chemical stability despite extended storage and elevated temperatures.

It is yet a further object of this invention to provide a liquid, substantially nonaqueous detergent containing a solubilized imidoperacid which can contain enzymes therein which retain significant enzyme activity despite the presence of the imidoperacid oxidant.

It is a still further object of this invention to provide a liquid, substantially nonaqueous detergent containing a solubilized imidoperacid containing enzymes stably suspended in the liquid phase by means of the combination of an alkanolamine, especially triethanolamine, and a water soluble or dispersible polymer, especially polyethylene glycol.
