Description

Technical field

[0001] The subject of the present invention is a cosmetic composition comprising 6-hydroxybenzomorpholine of formula (II), hydroxyethyl-3,4-methylenedioxyaniline of formula (III) and at least one oxidation coloring base.

[0002] The present invention also relates to a method for dyeing keratin fibers such as hair, in which the composition as previously described is applied to the fibers.

[0003] Another subject of the present invention is the use of the composition according to the present invention for dyeing keratin fibers, especially human keratin fibers such as hair. Background art

[0004] It is known practice to dye keratin fibers and especially human hair with dye compositions containing oxidation dye precursors, such as oxidation coloring bases, in particular ortho-phenylenediamine or para-phenylenediamine, ortho-aminophenol or para-aminophenol, and heterocyclic compounds. These oxidation coloring bases are colorless or weakly colored compounds which, when combined with oxidation products, are capable of producing colored compounds by an oxidative condensation process.

[0005] It is also known that the hues obtained with them can be varied by combining these oxidation coloring bases with couplers or color modifiers (the latter being especially selected from aromatic meta-phenylenediamines, meta-aminophenols, meta-biphenols and certain heterocyclic compounds such as indole compounds).

[0006] The various molecules used as oxidation coloring bases and couplers allow a wide range of colors to be obtained.

[0007] "Permanent" dyeing is characterized by the use of oxidation dye precursors (bases and / or couplers) in the presence of an oxidizing compound. In order to be considered an effective dyeing, the latter needs to meet certain criteria. It must make it possible to obtain, between the tips and the roots of the same lock of hair, a chromaticity (also called selectivity) at the desired intensity and with as small a coloring difference as possible.

[0008] The dye must also be tolerant over time and must not degrade in the presence of external agents such as washing, light, bad weather, friction and sweat.

[0009] However, the dyeing results obtained are not always very satisfactory, especially in terms of selectivity, color buildup (especially to ensure good coverage of the hair, more particularly of white hair), chromaticity, intensity and / or persistence (especially with respect to successive shampooing operations), or in terms of tolerance to light or sweat.

[0010] Thus, there is a real need to develop compositions that can dye keratin fibers in a strong, long-lasting, slightly selective and colored manner, with good color build-up, and that can provide a coloring that is tolerant to the various erosive factors to which the fibers may be subjected, such as bad weather, washing and perspiration, and that can also give good dyeing properties even after storage for some time. Summary of the Invention

[0011] One subject of the present invention is thus a cosmetic composition comprising:

[0012] - at least one oxidation coupler selected from among 6-hydroxybenzomorpholine of formula (II), one of its addition salts, its solvates and / or solvates of its salts:

[0013]

[0014] - at least one oxidation coupler selected from among hydroxyethyl-3,4-methylenedioxyaniline of formula (III), one of its addition salts, its solvates and / or solvates of its salts:

[0015]

[0016] - one or more oxidation developing bases, their salts, their solvates and / or solvates of their salts, and mixtures thereof.

[0017] The composition according to the invention comprising a specific combination of two oxidation couplers and at least one oxidation developing base makes it possible to achieve the above objectives, in particular with regard to the intensity, color build-up and selectivity of keratin fiber dyeing, as well as with regard to the fastness of the coloring (especially with respect to shampooing operations).

[0018] The present invention also relates to a method for dyeing keratin fibers, in particular human keratin fibers such as hair, in which the composition as previously described is applied to said fibers.

[0019] The present invention also relates to the use of the composition according to the invention for dyeing keratin fibers, in particular human keratin fibers such as hair.

[0020] The present invention also relates to a multi-compartment device comprising at least a first compartment containing the composition according to the invention and at least a second compartment containing one or more oxidizing agents (preferably hydrogen peroxide) as described below.

The melting point can be measured using a differential scanning calorimeter (DSC), such as a calorimeter sold by TA Instruments under the name "MDSC 2920". In the present patent application, all melting points are determined at atmospheric pressure (1.013×10 5 Pa).

Fatty substances carry in their structure at least one hydrocarbon-based chain containing at least 6 carbon atoms and / or at least two sequences of siloxane groups. Additionally, fatty substances are generally soluble in organic solvents under the same temperature and pressure conditions, such as chloroform, dichloromethane, carbon tetrachloride, ethanol, benzene, toluene, tetrahydrofuran (THF), liquid petrolatum, or decamethylcyclopentasiloxane.

[0353] The following examples are used to illustrate the invention, however, they do not present a limiting nature. Detailed implementation mode

[0354] Example

[0355] In the following examples, unless otherwise specified, all amounts are shown as weight percentages of the active material relative to the total weight of the composition.

[0356] Composition A, A' (dye composition) and composition B (oxidizing composition) are prepared from the components whose contents are specified in the following table (% MA):

[0357] [Table 1]

[0358]

[0359] [Table 2]

[0360]

[0361]

[0362] Scheme:

[0363] In use, the dye compositions A and A' are mixed with 1.5 times their weight of the oxidizing composition B (6 g% H2O2).

[0364] Then each mixture is applied to a lock of hair containing 90% natural white hair (NW) and 90% permanently waved natural white hair (PWW) at a ratio of 5 g of the mixture / 1 g of hair.

[0365] After staying on a heating plate at 27 °C for 30 minutes, the hair is rinsed, washed with L'Oréal Professionnel Pro Classics universal concentrated shampoo diluted to 10%, and dried.

[0366] Colorimetric measurements are carried out using a KONICA MINOLTA CM-3600A spectrocolorimeter in the CIELab system (illuminant D65, angle 10°, including the highlight component).

[0367] In this system, L* represents brightness: the lower the value of L*, the darker, stronger and more intense the color obtained. Chromaticity is measured by the values a* and b*, where a* represents the green / red color axis and b* represents the blue / yellow color axis.

[0368] Selectivity is represented by the color difference ΔE between a lock of dyed natural non-permanently waved (NW) hair and a dyed permanently waved lock (PWW).

[0369] The ΔE value is calculated according to the following equation:

[0370]

[0371] In this equation, L*, a*, and b* represent the values measured on the dyed natural hair (NW) (symbolizing the root of the hair), and L0*, a0*, and b0* represent the values measured on the dyed permanently waved hair (PWW) (symbolizing the tip of the hair).

[0372] The larger the value of ΔE, the greater the color difference between the tress of natural hair and the tress of permanently waved hair, which indicates the poorer the coloring uniformity between the tip and the root of the hair and, thus, the greater the selectivity.

[0373] The lower the value of ΔE, the lower the color difference and, thus, the better the selectivity (more uniform coloring).

[0374] Selectivity:

[0375] The results are given in Table 3 below.

[0376] [Table 3]

[0377]

[0378] Compared with the comparative composition A', the composition A according to the invention results in a lower value of ΔE and, thus, in poorer selective coloring.

[0379] Therefore, the coloring obtained with the composition according to the invention is more uniform than the coloring obtained with the comparative composition.
