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.
