Abstract:
A personal care composition suitable for styling hair, comprising:(a) from about 0.01% to about 20% of a non-silicone containing polymer suitable for hair styling;(b) an organopolysiloxane microemulsion comprising:(i) an organopolysiloxane dispersed as particles in the microemulsion, wherein the organopolysiloxane is substantially free of amino groups in combination with hydroxyl groups and has an average particle size of less than about 80 nanometers, and(ii) a surfactant system for dispersing the organopolysiloxane in the microemulsion, which is compatible with the non-silicone containing polymer;wherein the amount of microemulsion is such that the personal care composition comprises from about 0.01% to about 10% of the organopolysiloxane; and(c) from about 0.1% to about 20% of a liquid hydrophilic non-polymeric cationic compound containing at least one quaternary ammonium moiety; and(d) a carrier comprising:(i) from about 3% to about 99%, by weight of the composition, of a first solvent selected from the group consisting of water; water soluble organic solvents; organic solvents which are strongly to moderately strong in hydrogen-bonding parameter; and mixtures thereof; wherein the first solvent is other than C.sub.1 -C.sub.3 monohydric alcohol, C.sub.1 -C.sub.3 ketone and C.sub.1 -C.sub.3 ether, and(ii) optionally, from about 0% to about 55% of a second solvent selected from the group consisting of C.sub.1 -C.sub.3 monohydric alcohols, C.sub.1 -C.sub.3 ketones, C.sub.1 -C.sub.3 ethers, and mixtures thereof.
