Conditioning compositions comprising coacervate and gel matrix
Disclosed are conditioning compositions comprising by weight: (a) from about 0.1% to about 10% of a cationic surfactant; (b) from about 0.05% to about 10% of a water-soluble polymer selected from the group consisting of a water-soluble anionic polymer, a water-soluble amphoteric polymer, and mixtures thereof; (c) from about 1.0% to about 10% of a high melting point fatty compound; and (d) an aqueous carrier; wherein the cationic surfactant and the polymer from a water-soluble complex; and wherein the cationic surfactant and the high melting point fatty compound from a gel matrix. The compositions are especially suitable for hair care products such as hair conditioning products for rinse-off use.
1. A method of preparation of a conditioning composition comprising the steps of:
(a) preparing a coacervate comprising the steps of:
(a1) mixing a part of from about 0.1% to about 10% of a cationic surfactant and from about 0.05% to about 10% of a water-soluble polymer selected from the group consisting of a water-soluble anionic polymer, a water-soluble amphoteric polymer, and mixtures thereof, in a part of an aqueous carrier to form a coacervate;
(b) preparing a gel matrix comprising the step of:
(b1) mixing the rest of the cationic surfactant, a high melting point fatty compound, and the rest of aqueous carrier at a temperature of from about 80° C. to about 90° C. until the components are homogenized, and no solids are observed;
(b2) the mixture is then cooled to from about 50° C. to about 60° C. and maintained at this temperature to form a gel matrix;
(c) mixing the coacervate and the gel matrix.
