A bleaching composition and method of using is provided wherein the composition comprises an effective amount for bleaching of an organic peroxyacid whose structure includes a percarboxylic and a carboxylic acid or a salt functional unit; an effective amount of manganese complex having a formula selected from the group consisting of: [LMnX3]Y(1) wherein Mn is manganese; X is a coordinating species selected from the group consisting of: RO-, Cl-, Br-, I-, F-, NCS-, N3-, I3-, NH3, NR3, RCOO-, RSO3-, RSO4-, OH-, O22-, HOO-, H2O, SH-, CN-, OCN-, and S42- and combinations thereof; R is a C1-C20 radical selected from the group consisting of alkyl, cycloalkyl, aryl, benzyl and radical combinations thereof; at least two R radicals may also be connected to one another so as to form a bridging unit between two oxygens that coordinate with the manganese; L is a ligand selected from a C3-C60 radical having at least 3 nitrogen atoms coordinating with the manganese; and the formula: <IMAGE> (2) wherein Mn is manganese in a +III or +IV oxidation state and X, L and Y are as defined above; and from about 0.5 to about 50 wt. % of a surfactant. The pH range of the compositions of the invention is from about 7 to about 10. |
