Official abstract text for this publication.
The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

The invention claimed is: 1. A composition consisting of: (a) a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge wherein said first polyelectrolyte is a homopolymer of diallyl dimethyl ammonium chloride (“DADMAC”); (b) a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge in which the anionic moiety is selected from the group consisting of carboxylic acid, sulfonic acid and mixtures thereof; (c) an oxidant selected from the group consisting of hypohalous acid, hypohalite and mixtures thereof; (d) water; (e) optionally, a fragrance, a hydrotrope, a colorant, a dye, a buffer, a chelating agent, an electrolyte, an anti-microbial agent, a solvent, a stain and soil repellent, a lubricant, an odor control agent, a perfume, a fragrance release agent, an acid, a base, a solubilizing material, a stabilizer, a thickener, a defoamer, a cloud-point modifier, a preservative, a water immiscible solvent, an enzyme, and mixtures thereof; and (f) wherein the composition is free of precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte; and (g) wherein the composition has a viscosity of less than about 1,000 centipoise; and (h) wherein upon dilution, the composition forms a polyelectrolyte complex. 2. The composition of claim 1 , wherein said anionic moiety in the second polyelectrolyte is a carboxylic acid. 3. The composition of claim 2 , wherein the carboxylic acid is a maleic acid. 4. The composition of claim 2 , wherein the carboxylic acid is a methacrylic acid. 5. The composition of claim 1 , wherein the composition comprises a base. 6. The composition of claim 1 , wherein the composition comprises a buffer. 7. The composition of claim 1 , wherein the composition comprises a fragrance. 8. The composition of claim 1 , wherein the composition comprises a hydrotrope.
