Hair conditioner composition utilizing a heat styling responsive film

Abstract

A hair care composition having a combination of a high melting point wax to provide a hydrophobic film (frizz resistance) and thermo-pliable film (heat styling response), along with a lightweight conditioner, to produce a hair care composition that is far less susceptible to buildup than traditional products currently marketed.

Claims

1. A hair care composition consisting of: a) 1.5% by weight, behentrimonium chloride; b) 1.5% by weight, behenamidopropyl dimethylamine; c) 5% by weight, cetearyl alcohol; d) 0.75% by weight, carnauba wax; and e) deionized water, a pH adjuster, fragrance, and preservative to bring total mass of the composition to 100% by weight.

2. A method for styling hair comprising applying the hair care composition of claim 1 to rinsed hair, massaging through hair for about 5 seconds to about 5 minutes, rinsing composition out of the hair.

3. A method for styling hair comprising applying the composition of claim 1 to damp or towel-dried hair.

Description

DETAILED DESCRIPTION

(1) The present invention provides the qualities expected from a conditioner coupled with a unique thermo-pliable film that responds to heat generated by common consumer hair styling appliances. The composition may be applied to wet hair as a rinse off product and/or applied to damp or dry hair as a leave-on product.

(2) This thermo-pliable hair care and styling composition comprises an alkyl amine cationic surfactant having a molecular weight from about 400 g/mol to about 500 g/mol. The amount of alkyl amine cationic surfactant present in the composition may range from about 0.1% to about 7% by weight of, or from about 0.1 to about 5% by weight, or from about 1% to about 3% by weight, or from about 2% to about 5% by weight. The alkyl amine cationic surfactant may be selected from behentrimonium chloride, behenamidopropyl dimethylamine, behentrimonium methosulfate, and mixtures thereof.

(3) The composition may also contain from about 0.1% to 15% long chain fatty alcohols. Examples of such alcohols include behenyl alcohol, cetyl alcohol, stearyl alcohol, cetearyl alcohol, arachidyl alcohol, and mixtures thereof. The melting point of long chain fatty alcohol is from about 45° C. to about 80° C.

(4) The composition may also contain a high melting point waxy material, having a melting point from about 65° C. to about 90° C., present in amounts ranging from about 0.1% to about 5% (by weight); 1% to about 3% (by weight); or from about 0.75% to about 1.5% (by weight). Specifically, the high melting point waxy material may be selected from natural waxes, hydrocarbon waxes, and mixtures thereof, for instance, and not limited to, paraffin wax, ozokerite wax, ceresine wax, carnauba wax, rice bran wax, and mixtures thereof. Also, the composition may also contain from about 0.1 to 3% of neutralizing C.sub.2 to C.sub.4 carboxylic acid with an individual pK.sub.a from about 3.1 to about 4.6. Such neutralizing carboxylic acids may be selected from oxalic acid, glycolic acid, lactic acid, succinic acid, malic acid, and mixtures thereof. A suitable hair care carrier may also be utilized, wherein the point at which the composition first begins to melt is less than or equal to any solid materials utilized in the composition. The ratio of the cationic surfactant to the long chain fatty alcohol is from about 1:4 to about 1:1.

(5) The onset of melting point (first detectable melting point) for the overall composition is from about 46° C. to about 90° C.

(6) Generally, for this hair care composition, crystallization point(s) of the composition are usually not less than about 46° C.

(7) The hair composition may be in a form chosen from a liquid, a solution, an emulsion, a cream, a gel, a paste, a mousse, a foam, or any other form that is suitable for application to keratin fibers.

(8) Examples of the hair care composition include but are not limited to the following:
