Abstract
An amido peroxyacid compound is provided having the formula: ##STR1## wherein R is selected from the group consisting of C.sub.1 -C.sub.12 alkylene, C.sub.5 -C.sub.12 cycloalkylene, C.sub.6 -C.sub.12 arylene and radical combinations thereof; PA1 R.sup.1 and R.sup.2 are independently selected from the group consisting of H, C.sub.1 -C.sub.16 alkyl and C.sub.6 -C.sub.12 aryl radicals and a radical that can form a C.sub.3 -C.sub.12 ring together with R.sup.3 and both nitrogens; PA1 R.sup.3 is selected from the group consisting of C.sub.1 -C.sub.12 alkylene, C.sub.5 -C.sub.12 cycloalkylene and C.sub.6 -C.sub.12 arylene radicals, and provided when R.sup.3 is arylene and when n' and m' are each zero, R is other than C.sub.5 alkylene; PA1 n and n' each are an integer chosen such that the sum thereof is 1; PA1 m and m' each are an integer chosen such that the sum thereof is 1; and PA1 M is selected from the group consisting of H, alkali metal, alkaline earth metal, ammonium, alkanolammonium cations and radicals and combinations thereof. PA1 The amido peroxyacid compound is useful for bleaching substrates such as stained laundry.
