Abstract
The invention relates to polymer-micelle complex. The polymer-micelle complexes include a positively charged micelle selected from the group consisting of a monomeric quaternary ammonium compound, a monomeric biguanide compound, and mixtures thereof. The positively charged micelle is electrostatically bound to a water-soluble polymer bearing a negative charge. The polymer does not comprise block copolymer, latex particles, polymer nanoparticles, cross-linked polymers, silicone copolymer, fluorosurfactant, or amphoteric copolymer. The compositions do not form a coacervate, and do not form a film when applied to a surface.
