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) 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) 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; (c) an oxidant; (d) a fragrance; (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; (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; and (i) wherein the composition does not comprise a polymer fluorosurfactant derived from polymerization of fluorinated oxetane. 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 surfactant. 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. 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) 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; (c) an oxidant; (d) a dye; (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 upon dilution, the concentrate composition forms a polyelectrolyte complex from the first polyelectrolyte and the second polyelectrolyte; and (g) 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; and (h) wherein the composition does not comprise a polymer fluorosurfactant derived from polymerization of fluorinated oxetane. 9. The composition of claim 8 , wherein the composition further comprises a buffer. 10. The composition of claim 8 , wherein the composition further comprises a surfactant. 11. The composition of claim 8 , wherein the composition further comprises a fragrance. 12. The composition of claim 8 , wherein the composition further comprises a chelating agent. 13. The composition of claim 8 , wherein the composition further comprises a hydrotrope. 14. The composition of claim 8 , wherein the composition further comprises a thickener.
