Abstract

The present invention relates to conditioning shampoo compositions having improved stability and conditioning benefits. These compositions comprise a surfactant system further comprising a detersive anionic surfactant and a stabilizing surfactant; a fatty compound selected from the group consisting of fatty alcohols, fatty acids, fatty alcohol derivatives, fatty acid derivatives, and mixtures thereof; a hair conditioning agent selected from the group consisting of nonvolatile dispersed silicone conditioning agents, hydrocarbon conditioning agents, water soluble cationic polymeric conditioning agents, and mixtures thereof, and water. The present invention also relates to methods for cleansing and conditioning the hair.

Claims

1. A hair conditioning shampoo composition comprising, by weight:

(a) from about 5% to about 50% of a detersive anionic surfactant;

(b) from about 0.05% to about 20% of a stabilizing surfactant selected from the group consisting of amphoteric surfactants, cationic surfactants, and mixtures thereof;

(c) from about 0.01% to about 10% of a fatty compound selected from the group consisting of fatty alcohols, fatty acids, alkyl ethers of fatty alcohols, alkoxylated fatty alcohols, alkyl ethers of alkoxylated fatty alcohols, fatty acid esters of fatty alcohols having from about 10 to about 30 carbon atoms, fatty acid esters of alkyl ethers of fatty alcohols, fatty acid esters of alkoxylated fatty alcohols, fatty acid esters of alkyl ethers of alkoxylated fatty alcohols, hydroxy-substituted fatty acids, and mixtures thereof;

(d) from about 0.05% to about 20% of a hair conditioning agent comprising a water soluble cationic polymeric conditioning agent and a hydrocarbon conditioning agent;

(e) from about 0.025% to about 1.5% polyalkylene glycol having the formula;

##STR13## wherein R is selected from the group consisting of H, methyl and mixtures thereof, and n is an integer from about 1500 to about 25,000;

(f) from about 0.05% to about 20% by weight, of a nonvolatile dispersed silicone conditioning agent selected from the group consisting of arylated silicones having refractive indices of about 1.46 or higher; and

(g) water.

2. A hair conditioning shampoo composition according to claim 1 further comprising silicone resin.

3. A hair conditioning shampoo composition according to claim 1, wherein the stabilizing surfactant comprises an amphoteric surfactant selected from the group consisting of cetyl dimethyl betaine, cocamidopropyl betaine, stearyl dimethyl betaine, cocamidopropyl hydroxy sultaine and mixtures thereof, and a cationic surfactant having the formula:

space="preserve" listing-type="equation"> R.sub.1 R.sub.2 R.sub.3 R.sub.4 N!.sup.+ X.sup.-

wherein R₁, R₂, R₃, and R₄ are each independently selected from the group consisting of alkyls having from 1 to about 22 carbon atoms, and X is selected from the group consisting of chloride, bromide, iodide, acetate, phosphate, nitrate, sulfate, methyl sulfate, ethyl sulfate, tosylate, lactate, citrate, glycolate and mixtures thereof.

4. A hair conditioning shampoo composition according to claim 1, further comprising from about 0. 1% to about 4%, by weight, antidandruff agent.
