Abstract
A bleaching composition and a method of using the same. The composition comprising: (i) from about 0.1 to about 50% by weight of an amido peroxyacid having the structure: ##STR1## wherein, R, R.sup.1, R.sup.2, R.sup.3, n, n', m, m', and M are as defined in the specification; and (ii) from about 0.5 to about 50% by weight of a surfactant.
Claims17
A method for bleaching a substrate comprising applying to said substrate an effective amount to remove stain of an amido peroxyacid having the structure:
- ##STR7## 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;
- 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;
- 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;
- n and n' each are an integer chosen such that the sum thereof is 1;
- m and m' each are an integer chosen such that the sum thereof is 1;
- and
- M is selected from the group consisting of H, alkali metal, alkaline earth metal, ammonium, alkanolammonium cations and radicals and combinations thereof.
