1. A liquid antimicrobial laundry treatment composition that is stabilized without the use of phosphorus-containing components, the composition consisting of:
(a) about 0.1% to about 10% by weight of a peroxide;
(b) about 0.5% to about 2′ by weight, of an alkanoyl oxybenzene sulfonate peroxide activator;
(c) about 2% to about 10% by weight of a nonionic alkoxylated alcohol surfactant with a cloud point above about 45° C.;
(d) about 0.05% to about 0.5% by weight of an anionic surfactant;
(e) an organic or inorganic acid pH adjusting agent;
(f) at least about 85% by weight water;
(g) wherein the composition has a pH of about 5 or less;
(h) optionally, one or more of a polysaccharide gum thickener that is stable in acidic conditions, an optical brightener, a polymeric suspension agent, an enzyme, a dye, colorant or pigment, a fragrance or perfume, a solvent, a co-surfactant, a hydrotrope, a stain and soil repellant, a lubricant, a solubilizing agent, a stabilizer, a defoamer, a preservative, or a buffer;
(i) wherein the composition provides at least about a 3 log reduction against a bacterial population when used “through the wash”; and
(j) wherein the composition provides at least about 80% peroxide stability over a period of at least about 6 months.
