Composition comprising a particular oxidation dye precursor, a particular amino silicone and a polyol

[0001] This is a National Stage Application of PCT/EP2022/085113, filed internationally on Dec. 9, 2022, which claims priority to French Application No. 2113301, filed on Dec. 10, 2021, which are incorporated by reference herein in their entireties.

[0002] The invention relates to a composition comprising a combination of a particular oxidation base, a (poly)oxyalkylenated amino silicone and a polyol, notably for dyeing keratin fibers.

[0003] The invention also relates to a process for dyeing keratin fibers, notably the hair, using this composition.

[0004] Finally, the invention relates to the use of such a composition for dyeing keratin fibers, and notably the hair.

[0005] Many people have sought for a long time to modify the color of their hair and in particular to mask their gray hair.

[0006] It is known practice to dye keratin fibers, in particular human keratin fibers such as the hair, to obtain “permanent” colorings with dyeing compositions containing oxidation dye precursors, notably oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds via a process of oxidative condensation.

[0007] 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 used as oxidation bases and couplers allows a wide range of colors to be obtained. However, the use of these dye compositions may have a certain number of drawbacks.

[0008] Specifically, after application to keratin fibers, the dyeing power obtained may not be entirely satisfactory, or may even be weak, and lead to a restricted range of colors.

[0009] The colorings may also be insufficiently persistent with respect to external agents such as light, shampoo or perspiration, and may also be too selective, i.e. the difference in coloring is too great along the same keratin fiber that is differently sensitized between its end and its root.

[0010] There is a real need for a composition for dyeing keratin fibers, in particular human keratin fibers such as the hair, which does not have the abovementioned drawbacks, i.e. which is capable of leading to a coloring with an intense color with improved persistence and also good coverage of gray hair and good selectivity, and which is capable of giving good dyeing performance, even after a period of storage.

[0011] These aims and others are achieved by the present invention, one subject of which is thus a composition, preferably a cosmetic composition, notably for dyeing keratin fibers, comprising:

• • [0012] at least one oxidation base chosen from 2-β-hydroxyethyl-para-phenylenediamine of formula (I), an addition salt thereof, solvates thereof and/or solvates of the salts thereof:

[0013]

• • [0014] at least one (poly)oxyalkylenated amino silicone, and
  • [0015] at least one polyol.

[0016] The present invention also relates to a process for dyeing keratin fibers, in which the composition according to the invention is applied to said fibers.

[0017] According to a preferred embodiment, the composition according to the invention is a composition for dyeing keratin fibers, preferably human keratin fibers, notably the hair.

[0018] The composition according to the invention may notably lead to chromatic, powerful, intense and sparingly selective colorings, i.e. colorings that are uniform along the length of the fiber.

[0019] It also allows various shades to be achieved in a very wide range of colors. It also enables good color build-up.

[0020] This composition also gives particularly good coverage of depigmented keratin fibers such as gray hair.

[0021] A subject of the invention is also a kit comprising, in a first compartment, a composition as defined previously and, in a second compartment, an oxidizing composition comprising at least one chemical oxidizing agent.

[0022] According to the invention, the term “chemical oxidizing agent” means an oxidizing agent other than atmospheric oxygen.

[0023] Other subjects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and the examples that follow.

[0024] In the text hereinbelow, unless otherwise indicated, the limits of a range of values are included in that range, notably in the expressions “between” and “ranging from . . . to . . . ”.

The melting point may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by the company TA Instruments.

Dyeing Protocol

[0400] The dye compositions A1 and C1 are each mixed respectively with the oxidizing composition B1 in a 1+1.5 weight ratio.

[0401] Each of the mixtures is applied to locks of hair containing 90% white hairs, which are natural (NW), on the one hand, and permanent-waved (PWW), on the other hand, at a rate of 5 g of mixture per 1 g of hair.

[0402] After a leave-on time of 30 minutes on a hotplate at 27° C., the hair is rinsed, washed with a standard shampoo, and then dried.

Results

[0403] The coloring of the hair is evaluated as in example 1 in the L*a*b* system, using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0404] In this system, L* represents the lightness. The chromaticity is measured by the values a* and b*, with a* representing the red/green axis and b* the yellow/blue axis.

[0405] The selectivity is represented by the color difference ΔE between the locks of dyed natural (NW) and dyed permanent-waved (PWW) hair, ΔE being obtained from the formula:

[0406] $\Delta E=\sqrt{{\left(L^{*}-L_0^{*}\right)}^2+{\left(a^{*}-a_0^{*}\right)}^2+{\left(b^{*}-b_0^{*}\right)}^2}$

[0407] In which L* represents the intensity, a* and b*, the chromaticity of dyed natural hair and L0* represents the intensity and a0* and b0* the chromaticity of the dyed permanent-waved hair. The lower the value of ΔE, the lower the selectivity and the more uniform the coloring along the hair.

[0408]

TABLE 3
Composition	Hair type	L*	a*	b*	ΔE
A1 + B1	NW	20.56	−0.22	3.03	3.66
(invention)	PWW	18.69	−0.06	−0.11
C1 + B1	NW	21.60	−0.42	3.79	6.01
(comparative)	PWW	16.33	0.14	0.96

[0409] Composition A1 according to the invention leads to a lower ΔE value, and thus to better selectivity, relative to the comparative composition C1.
