Technical Field

The present invention relates to a hair care composition comprising: a cationic surfactant system; a high melting point aliphatic compound; fatty acid esters of benzoic acid; a non-volatile hydrocarbon oil; and an aqueous carrier. The compositions of the present invention provide conditioning benefits, especially dry conditioning benefits, while providing improved clean feel.

Background

Various methods have been developed to condition hair. One common method of providing conditioning benefits is through the use of conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits.

For example, chinese patent application publication No. 103735428A discloses a keratin conditioning agent purportedly useful for restoring smoothness and damage to hair, and discloses a composition comprising: 4-7 wt% of cetostearyl alcohol, 1-2 wt% of behenyl trimethyl ammonium chloride, 1-3 wt% of cetyl trimethyl ammonium chloride, 0.5-1 wt% of 12-15C benzoate, 1-3 wt% of cyclopentasiloxane, 0.5-1.5 wt% of dimethyl siloxane, 0.5-1 wt% of diamino siloxane.

Another example is WO 2010076484 a, which discloses an anhydrous cosmetic composition (I) comprising one or more liquid polyesters obtained by condensing dimers and/or trimers of unsaturated fatty acids and saturated linear diols, one or more volatile oils and one or more non-volatile oils, wherein the volatile oil/non-volatile oil weight ratio is greater than 1.5. The compositions are said to provide good cosmetic properties to the hair, preferably good shine to the hair without greasy or sticky effects. The present WO publication also discloses a composition comprising (in weight%): 10% ethanol; 5% 12-15C benzoic acid ethanol; and 80% isododecane.

There remains a need for such hair care compositions to provide conditioning benefits, especially dry conditioning benefits, while providing improved clean feel.

None of the prior art provides all of the advantages and benefits of the present invention.

(c) from about 0.1% to about 15% of a fatty acid ester of benzoic acid;

(d) from about 0.1% to about 15% of a non-volatile hydrocarbon oil; and
