## Abstract

## Background
BACKGROUND OF THE INVENTION
Disclosed herein is a composition, in cream form, for the oxidation dyeing of keratin fibers, for example human keratin fibers, such as the hair.
It is a known practice to dye keratin fibers, such as human hair, with dye compositions comprising oxidation dye precursors, generally known as “oxidation bases”, such as ortho- and para-phenylenediamines, ortho- and para-aminophenols, and heterocyclic bases.
Oxidation dye precursors are compounds that are initially uncolored or only weakly colored, which develop their dyeing power on the hair in the presence of oxidizing agents, leading to the formation of colored compounds. The formation of these colored compounds may result either from an oxidative condensation of the oxidation bases with themselves or from an oxidative condensation of the oxidation bases with coloration modifiers, or “couplers”, which may be present in the dye compositions used in oxidation dyeing and may be represented for example by meta-phenylenediamines, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds.
The variety of molecules used, which comprise on the one hand the oxidation bases and on the other hand the couplers, may allow a wide range of colors to be obtained.
BRIEF SUMMARY OF THE INVENTION
The present invention is directed to a composition for the oxidation dyeing of keratin fibers, such as the hair, comprising, in a medium suitable for dyeing:

    
    
        a) greater than 10% by weight of at least one fatty acid alkanolamide;
        b) at least one C6-C36 dicarboxylic acid;
        c) at least one water soluble base capable of reacting with (b) to form a soap;
        d) at least one conditioning polymer; and
        e) at least one oxidation dye.
    
    


The present invention is also directed to a ready-to-use hair dyeing composition containing:

    
    
        a) greater than 10% by weight of at least one fatty acid alkanolamide;
        b) at least one C16-C36 dicarboxylic acid;
        c) at least one water soluble base capable of reacting with (b) to form a soap;
        d) at least one conditioning polymer;
        e) at least one oxidation dye; and
        f) at least one oxidizing agent.
    
    


The present invention is also directed to a process for dyeing keratin fibers, such as hair, by contacting the keratin fibers with the above-disclosed ready-to-use dyeing composition.
The present invention is also directed to a multi-compartment kit for the oxidation dyeing of keratin fibers, such as hair, the kit containing:
a) a first compartment comprising: i) greater than 10% by weight of at least one fatty acid alkanolamide; ii) at least one C6-C36 dicarboxylic acid; iii) at least one water soluble base capable of reacting with (b) to form a soap; iv) at least one conditioning polymer; and v) at least one oxidation dye, and

b) a second compartment comprising at least one oxidizing agent.

It has been surprisingly discovered that by combining the above-disclosed ingredients, a dyeing composition, in cream form, may be formulated yielding excellent color deposition on hair treated therewith, while at the same time imparting desirable conditioning properties.

Each dyeing composition was mixed, at the time of use, in a plastic bowl and for 2 minutes, with the oxidizing composition given above, in an amount of 1 part of dyeing composition per 1 part of oxidizing composition. The mixture obtained was applied to swatches of 3 grams of permed and unpermed natural grey hair which is 90% white and allowed to act for 30 minutes in a bath ratio: 10 g of mixture per 1 g of hair and were laid out flat on a support.
The swatches were then rinsed with water, they were washed with shampoo and again rinsed with water, and then dried and disentangled.
Example 1
Colorimetric Test on Use of Fatty Amides
The color of the dye-treated swatches was measured using a Minolta CM2002 colorimeter in the L*a*b* system. In the L*a*b* system, the 3 parameters denote, respectively, the intensity (L*), the shade (a*) and the saturation (b*).
According to this system, the greater the value of L, the lighter or less intense the color. Conversely, the lower the value of L, the darker or more intense the color.
The ΔL or the difference between the L value for the dye-treated hair versus the L value for the control hair sample represents a change in the value of L: the more negative the ΔL value is, the darker the color that is deposited on the hair. ΔL=Lt (dye-treated hair)−Lc (control, 90% grey hair)
The results are collated in Table (1) below:

Conclusion: The ΔL values for Formula A for both unpermed and permed hair were more negative compared to those for Formula B for both unpermed and permed hair, which indicated that more color was deposited on the hair treated with Formula A which contained the fatty amides.
Example 2
Evaluation of Conditioning Properties on Use of Conditioning Polymers Versus Conditioning Non-polymeric Agents
The dyeing compositions, Formula A and Formula C, were applied to swatches of 3 grams of unpermed natural grey hair which is 90% white. Three complete application cycles of dye treatment, then shampoo, were performed on each swatch sample.
The swatches were evaluated for conditioning properties by a panel of 10 expert evaluators. The hair treated with Formula A above, which contained the conditioning polymers, was rated by 8 out of the 10 expert evaluators as being smoother and softer than hair treated with Formula C, which was considered rough-feeling.
Example 3
Colorimetric Test on Use of Dilinoleic Acid
Dyeing Compositions: Formulas D and E contained 5% and 7.5% dilinoleic acid, respectively, Formula F did not contain dilinoleic acid and Formula G contained oleic acid instead of the diacid.
