Description

Composition comprising an oxidation dye, an alkaline agent, a cationic galactomannan gum, a particular solid fatty acid and an anionic acrylic polymer

The invention relates to a composition comprising at least one oxidation dye, at least one alkaline agent, at least one cationic galactomannan gum, at least one solid fatty acid having a hydrocarbon chain comprising at least 14 carbon atoms and at least one anionic acrylic polymer.

The invention also relates to a process for coloring keratin fibers, in particular hair, using this composition.

The invention finally relates to the use of such a composition for coloring keratin fibers, and in particular hair.

For a long time, many people have sought to change the color of their hair, and in particular to hide their white hair.

It is known to dye keratin fibers, in particular human keratin fibers such as hair to obtain so-called permanent colorings with dye compositions containing oxidation dye precursors, in particular oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolo-pyridines. These oxidation bases are colorless or weakly colored compounds which, associated with oxidizing products, can give rise to colored compounds through an oxidative condensation process.

It is also possible to vary the shades obtained with these oxidation bases by combining them with couplers or color modifiers. The variety of molecules involved in the oxidation bases and couplers makes it possible to obtain a rich palette of colors.

However, the implementation of these dye compositions can present a certain number of disadvantages.

Indeed, after application to the keratin fibers, the dyeing power obtained may not be entirely satisfactory, or even low, and lead to a restricted range of colors. Furthermore, they do not give complete satisfaction in terms of cosmetic properties of the hair.

The colorings may also not be sufficiently tenacious in the face of external agents such as light, shampoos, perspiration and also be too selective, that is to say that the coloring difference is too great along the the same keratin fiber which is differently sensitized between its tip and its root.

Furthermore, coloring compositions often include raw materials for which regulatory conditions are increasingly strict. It is therefore necessary to develop compositions comprising alternative compounds.

Consumers are also looking for coloring products that are more environmentally friendly, in particular based on ingredients with a more favorable environmental profile, and which have good qualities of use, are easy to use and lead to good tinctorial properties. , as well as good cosmetic properties.

Thus, there is a real need to provide a composition for coloring keratin fibers, in particular human keratin fibers such as hair, that is more environmentally friendly, and does not have the drawbacks mentioned above, i.e. that is to say which is capable of leading to good dyeing performances: good rise, intensity and chromaticity of the color while having low selectivity and good tenacity, with good coverage of white hair, as well as good qualities of use and good cosmetic properties.

These and other goals are achieved by the present invention which therefore relates to a composition comprising:
- at least one oxidation dye chosen from oxidation bases, couplers and mixtures thereof;
- at least one alkaline agent;
- at least one cationic galactomannan gum;
- at least one solid fatty acid having a hydrocarbon chain comprising at least 14 carbon atoms;
- at least one anionic acrylic polymer.

The composition according to the invention makes it possible, in particular, to produce chromatic colorings that are powerful, intense and not very selective, that is to say colorings which are homogeneous along the fiber. It also allows you to achieve different shades, with good coverage of white hair and in a very wide range of colors. In addition, it therefore allows a good rise of color.

Furthermore, the composition according to the invention has good qualities of use, in particular a creamy texture allowing rapid and easy mixing with an oxidizing composition if necessary, easy and homogeneous distribution over the entire hair. The composition according to the invention has good stability over time.

In addition, the composition according to the invention leads to good cosmetic properties, particularly in terms of feel, shine and detangling when rinsing the hair coloring.

The invention also relates to a kit comprising in a first compartment a composition as defined above and in a second compartment an oxidizing composition comprising at least one chemical oxidizing agent.

By “ chemical oxidizing agent ” according to the invention is meant an oxidizing agent other than oxygen in the air.

Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and examples which follow.

In what follows, and unless otherwise indicated, the limits of a domain of values are included in this domain, in particular in the expressions “between” and “ranging from… to…”.

At the time of use, each of the coloring compositions A1 and A2 is mixed with 1 ½ times its weight of oxidant O. Each of the mixtures is then applied to a strand of 90% white, permed hair at a rate of 5g of mixture/g of hair or on strands of 90% natural white hair (BN) at a rate of 5g of mixture per 1g of hair.

After 30 minutes of application on a thermostatically controlled plate at 27°C, the hair is rinsed, washed with a standard shampoo and dried.

Results

The colorimetric measurements were carried out using a KONICA MINOLTA-CM-3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

In this system, L* represents clarity. The lower the value of L*, the darker and more powerful the coloring obtained. Chromaticity is measured by the a* and b* values, with a* representing the red/green axis and b* the yellow/blue axis.

The rise (ΔE) was evaluated as follows.

The variation in coloring between the strands of uncolored hair and colored hair is defined by (ΔE) according to the following equation:

In this equation, L*, a* and b* represent the values measured on strands of hair after coloring and L ₀ *, a ₀ * and b ₀ * represent the values measured on strands of hair before coloring. The larger the value of ∆E, the stronger the rise in color.

Composition A1 according to the invention comprising at least one solid fatty acid according to the invention leads to a higher ΔE value and therefore to a better rise in color compared to composition A2 not comprising such fatty acids.

Furthermore, the values of L* allow us to conclude that the fibers colored with A1 have a better power in comparison with those colored with A2.

The selectivity was evaluated as follows.
Color selectivity is the variation in color between colored natural hair and colored permed hair. Natural hair is representative of the nature of the hair at the root while permed hair is representative of the nature of the hair at the tip.

Selectivity is measured by ΔE', which is the variation in color between natural hair and permanent hair, is obtained from the formula:

In which L* represents the intensity a* and b*, the chromaticity of natural colored hair and L ₀ * represents the intensity and a ₀ * and b ₀ * the chromaticity of permanent colored hair. The lower the value of ΔE', the lower the selectivity and the more uniform the coloring along the hair.

Composition A1 according to the invention comprising at least one solid fatty acid according to the invention leads to a lower ΔE' value and therefore to better color selectivity in comparison to composition A2 not comprising such fatty acids.
