Abstract

Abstract Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-insoluble surfactant dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

A hair conditioning composition characterized in that it comprises: (a) from 80% to 99.9% of a vehicle system which comprises: (A) from 0.2% to 5.0%, by weight of the hair conditioning composition, of a nonionic cellulose ether substituted with a long chain alkyl radical having 16 carbon atoms in an amount between 0.50% to 0.95%, by weight; a hydroxyethyl molar substitution of from 2.3 to 3.7; and an average molecular weight of unsubstituted cellulose of from 300,000 to 700,000; (B) from 0.05% to 3.0%, by weight of the hair conditioning composition, of hydrogenated tallow amide DEA; (C) from 0.05% to 0.3%, by weight of the hair conditioning composition of a chelating agent selected from ethylene diamine tetracetic acid, and salts thereof; citric acid, and salts thereof; and mixtures thereof; and (D) from 65% to 99%, by weight of the hair conditioning composition, of water; and (b) from 0.1 % to 20% of an active hair care component comprising; (A) from 0.5% to 15%, by weight of the hair conditioning composition, of a silicone conditioning agent which is selected from a combination of a volatile silicone fluid having a viscosity of less than 10 centipoise, and from 0.5% to 2.0% of a silicone gum having a viscosity of greater than 1,000,000 centipoise, at ratios of volatile fluid to gum of from 85:15 to 50:50; and a combination of a non-volatile silicone fluid having a viscosity of less than 100,000 centipoise, and from 0.5% to 2.0% of a silicone gum having a viscosity of greater than 1,000,000 centipoise, at ratios of non-volatile fluid to gum of from 60:40 to 40:60; and (B) from 0.5% to 2.0%, by weight of the hair conditioning composition, of dihydrogenated tallow dimethyl ammonium chloride; and (C) up to 1%, by weight of the hair conditioning composition, of a fatty alcohol selected from cetyl alcohol, stearyl alcohol, and mixtures thereof; wherein said hair conditioning composition comprises no more than 0.5% of water-soluble surfactants.
Claim 27
Independent Claim 42 words
A method for manufacturing a hair conditioning composition according to any of Claims 17-24 comprising the step of premixing the silicone conditioning agent, the quaternary ammonium compound, and at least a portion of the solvent prior to mixing with the remaining components.
