1. A formulation for use in neutralization of at least one toxant, said formulation comprising:
at least two solubilizing compounds, wherein at least one solubilizing compound is a cationic surfactant and at least one solubilizing compound is a cationic hydrotrope;
at least one reactive compound, wherein said at least one reactive compound is selected from the group consisting of hydrogen peroxide, urea hydrogen peroxide, hydroperoxycarbonate, peracetic acid, sodium perborate, sodium peroxypyrophosphate, sodium peroxysilicate, and sodium percarbonate; and
at least one water-soluble bleaching activator selected from the group consisting of ethylene glycol diacetate, propylene glycol monomethyl ether acetate, methyl acetate, dimethyl glutarate, diethylene glycol monoethyl ether acetate, and propylene glycol diacetate, and combinations thereof;
wherein said at least two solubilizing compounds, said at least one reactive compound, and said at least one water-soluble bleaching activator, when mixed with water and exposed to the at least one toxant, neutralizes the at least one toxant.
