Hair Conditioning Composition Comprising Cationic Surfactant System and Direct Dye

 

 

Abstract or Summary of the Invention

 

Disclosed is a hair conditioning composition comprising: a cationic surfactant system of either (i) or (ii): (i) the system comprising: a salt of a mono-long alkyl quaternized ammonium and an anion wherein the anion is selected from the group consisting of C1-C4 alkyl sulfate, and mixtures thereof; and a di-long alkyl quaternized ammonium salt; or (ii) the system comprising: salts of mono-long alkyl amines wherein the mono-long alkyl group has 20 to about 24 carbon atoms; and a di-long alkyl quaternized ammonium salt; a high melting point fatty compound; a direct dye; and an aqueous carrier. The composition of the present invention provides improved coloring benefits, while providing conditioning benefits.

Method of Preparation

 

The conditioning compositions of “Ex. 1” through “Ex. 6”, “Ex. i” and “Ex. ii” as shown above can be prepared by any conventional method well known in the art. They are suitably made as follows

 

Cationic surfactants, high melting point fatty compounds and direct dyes are added to water with agitation, and heated to about 80°C. The mixture is cooled down to about 50°C. If included, silicone compounds, perfumes, preservatives are added to the mixture with agitation. Then the mixture is cooled down to room temperature.

 

Examples 1 through 6 are hair conditioning compositions of the invention which are particularly useful for rinse-off use. The embodiments disclosed and represented by the previous “Ex. 1” through “Ex. 6” have many advantages. For example, they provide color benefits while providing conditioning benefits. They are especially suitable for red or brown colored hair. Ex. i and “Ex. ii are control compositions.

 

Coloring benefit

 

With respect to the above compositions of Ex. 1, Ex. 4, Ex. i and Ex. ii, a coloring benefit is evaluated by the following method. Results of the evaluation are also shown below in Table 1.

 

Color deposition

 

Color deposition is evaluated as follows:

 

i)       The color of non-treated, non-colored hair sample (hereinafter Color N) is measured using an instrument called X-Rite SP64 Spectrophotometer.

ii)     The sample is treated with the composition 15 times as follows: 1 g of the composition is applied and evenly spread to the sample, then rinsed off from the sample. Then the sample is dried.

iii)    After l5cycle of the treatments, the color of the treated hair sample (hereinafter Color T) is measured using an instrument called X-Rite SP64 Spectrophotometer.

iv)   The L, a, b values for Color N and Color T are then compared to calculate the DE2000 measurements.
