Abstract

The invention relates to a polymer-micelle complex. The polymer-micelle complexes include a negatively charged micelle that is electrostatically bound to a water-soluble polymer bearing a positive 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.
