Abstract

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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A concentrate composition comprising: (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 poly(diallyldimethyl ammonium chloride) homopolymer; (b) about 0.001% to 0.19% by weight of a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge wherein said second polyelectrolyte comprises at least one of poly(acrylic acid), a copolymer of acrylic acid and maleic acid, a copolymer of acrylic acid and styrene, a copolymer of styrene sulfonic acid and maleic acid, a homopolymer of styrene sulfonic acid, or mixtures thereof; (c) about 0.1 to 10% by weight of a surfactant; (d) an oxidant; (e) wherein the composition is free of precipitates, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte; (f) wherein the composition has a viscosity of less than about 1,000 centipoise; (g) wherein upon dilution, the concentrate composition forms a polyelectrolyte complex from the first polyelectrolyte and the second polyelectrolyte; and (h) wherein R, the molar ratio of charged groups present on said first polyelectrolyte to oppositely charged groups present on said second polyelectrolyte, is from about 0.1 to 20. 2. The composition of claim 1 , wherein the composition further comprises a buffer. 3. The composition of claim 1 , wherein the composition further comprises a dye. 4. The composition of claim 1 , wherein the composition further comprises a fragrance. 5. The composition of claim 1 , wherein the composition further comprises a chelating agent. 6. The composition of claim 1 , wherein the composition further comprises a hydrotrope. 7. The composition of claim 1 , wherein the composition further comprises a thickener. 8. The composition of claim 1 , wherein the composition further comprises an acid. 9. The composition of claim 1 , wherein the composition further comprises a base. 10. The composition of claim 1 , wherein the composition further comprises a solvent. 11. A concentrate composition comprising: (a) about 0.001 wt % to about 5.0 wt % of a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge wherein said first polyelectrolyte is a poly(diallyldimethyl ammonium chloride) homopolymer; (b) a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge; (c) an oxidant comprising at least one of hydrogen peroxide, alkaline metal salts and/or alkaline earth metal salts of hypochlorous acid, hypochlorous acid, solubilized chlorine, any source of free chlorine, solubilized chlorine dioxide, acidic sodium chlorite, active chlorine generating compounds, active oxygen generating compounds, chlorine-dioxide generating compounds, solubilized ozone, sodium potassium peroxysulfate, sodium perborate, or combinations thereof; (d) wherein the composition is free of precipitates, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte; (e) wherein upon dilution, the concentrate composition forms a polyelectrolyte complex from the first polyelectrolyte and the second polyelectrolyte; and (f) wherein R, the molar ratio of charged groups present on said first polyelectrolyte to oppositely charged groups present on said second polyelectrolyte, is from about 0.1 to 20. 12. The composition of claim 11 , wherein the composition further comprises a buffer. 13. The composition of claim 11 , wherein the composition further comprises a dye. 14. The composition of claim 11 , wherein the composition further comprises a fragrance. 15. The composition of claim 11 , wherein the composition further comprises a chelating agent. 16. The composition of claim 11 , wherein the composition further comprises a hydrotrope. 17. The composition of claim 11 , wherein the composition further comprises a thickener. 18. The composition of claim 11 , wherein the composition further comprises an acid. 19. The composition of claim 11 , wherein the composition further comprises a base. 20. The composition of claim 11 , wherein the composition further comprises a solvent.
