Description

Title of the invention: Composition comprising at least N,N-dicarboxymethyl glutamic acid, at least one coloring agent, and at least one fatty amine

[0001] The present invention relates to a composition comprising at least N,N-dicarboxymethyl glutamic acid, at least one coloring agent, and at least one fatty amine. technical field

[0002] For a long time, many people have sought to change the color of their hair, and in particular to cover their white hair.

[0003] Two main modes of coloring of human keratin fibers, and in particular of hair, are known.

[0004] One of these two methods is oxidation or permanent coloring. This coloring method uses one or more oxidation dye precursors, usually one or more oxidation bases possibly associated with one or more couplers.

[0005] In general, oxidation bases are chosen from among ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, in association with oxidizing products, allow access to colored species.

[0006] Often, the nuances obtained with these oxidation bases are varied by associating them with one or more couplers, the latter being chosen in particular from among the aromatic meta-diamines, the meta-aminophenols, the meta-diphenols and certain heterocyclic compounds, such as indolic compounds.

[0007] The variety of molecules involved in the oxidation bases and couplers allows for a rich palette of colors. This type of coloring also allows for permanent coloring, but the use of oxidizing agents can lead to degradation of the keratin fibers.

[0008] The second coloring method, called direct or semi-permanent coloring, involves the application of direct dyes, which are molecules with an affinity for fibers and which remain colored even in the absence of an oxidizing agent added to the compositions containing them. Given the nature of the molecules used, these remain mostly on the surface of the fiber and penetrate relatively little into the fiber, compared to the small precursor molecules of oxidation dyes.

[0009] The direct dyes generally used are chosen from among the benzene, anthraquinone, nitropyridine, azo, methicillin, azo- direct dyes Methinic, xanthenic, acridinic, azinic, or triarylmethanic dyes. The chemical species used can be nonionic, anionic (acidic dyes), or cationic (basic dyes). Direct dyes can also be natural dyes.

[0010] Hair coloring using natural direct dyes has been known since antiquity.

[0011] Compositions containing one or more natural direct dyes are applied to the keratin fibers for a time necessary to obtain the desired color, then rinsed.

[0012] However, the resulting colors, while potentially highly chromatic, are temporary or semi-permanent because desorption from the surface and / or core of the fiber results in weak dyeing power and poor wash resistance. Furthermore, these compositions require relatively long processing times, ranging from several tens of minutes to several hours (overnight), depending on the desired intensity, without any control over the outcome. The result varies depending on the fibers being dyed and the nature of the natural dye(s) used.

[0013] Thus, there is a real need to make available a coloring composition for keratin fibers, in particular human keratin fibers such as hair, which does not have the disadvantages mentioned above, that is to say, which is capable of leading to a good rise, intensity and chromaticity of the color, while having low selectivity and good tenacity and which is capable of leading to good dyeing performance, even after a period of storage, while having good qualities of use. Description of the invention

[0014] The present invention therefore relates to a composition comprising:

[0015] a) at least one compound selected from N,N-dicarboxymethyl glutamic acid, its salts, its solvates, the solvates of its salts and their mixtures; b) at least one coloring agent selected from oxidation dyes, direct dyes, and mixtures thereof; c) at least one compound selected from fatty amines, their salts, or mixtures thereof.

[0016] According to a preferred embodiment, the composition according to the invention is a keratin fiber coloring composition, in particular hair.

[0017] The composition according to the invention makes it possible, in particular, to produce powerful, intense, and non-selective chromatic colorations, that is to say, colorations that are homogeneous along the fiber. It also makes it possible to achieve different shades in a very wide range of colors. In addition, it allows for good color uptake and tenacity.

[0018] Furthermore, the composition according to the invention exhibits good performance qualities, notably a creamy texture and easy, even distribution throughout the hair. The composition according to the invention also exhibits good stability over time, in particular minimal or no change in its viscosity and / or pH during storage.

[0019] The expression "at least one" means one or more.

[0020] Unless otherwise indicated, the bounds of a range of values ​​are included in that range, in particular in the expressions "between" and "ranging from ... to ...".

[0021] For the purposes of the present invention, "hair" means the hair on the head. This term does not include body hair, eyebrows, or eyelashes. N,N-Dicarboxymethyl glutamic acid

[0516] Thus, the cellulosic polymers usable according to the invention can be chosen from unsubstituted celluloses, including in microcrystalline form, and cellulose ethers. Among these cellulosic polymers, a distinction is made between cellulose ethers, cellulose esters, and cellulose ester-ethers.

[0517] Among the non-ionic cellulose ethers, examples include (Cl-C4)alkylcelluloses such as methylcelluloses and ethylcelluloses (e.g., Ethocel Standard 100 Premium from DOW CHEMICAL); (poly)hydroxy(Cl-C4)alkylcelluloses such as hydroxymethylcelluloses, hydroxyethylcelluloses (e.g., Natrosol 250 HHR offered by AQUALON) and hydroxypropylcelluloses (e.g., Klucel EF from AQUALON); mixed (poly)hydroxy(Cl-C4)alkyl-(Cl-C4)alkylcelluloses such as hydroxypropyl methylcelluloses (e.g., Methocel E4M from DOW CHEMICAL), hydroxyethyl methylcelluloses, hydroxyethyl ethylcelluloses (e.g., Bermocoll E 481 FQ from AKZO NOBEL) and hydroxybutyl methylcelluloses.

[0540] (1) sold by the company CRODA under the trade name SP CRODAMOL MS MBAL-PA-(SG) Protocol

[0541] Each of the compositions A1 and A2 was applied to bleached hair strands at a rate of 5 g of composition per gram of strand. The strands were then placed on a plate heated to 27°C for 10 minutes. Afterward, the strands were rinsed and then dried. Results

[0542] The colorimetric measurements were carried out using a KONICA MINOLTA-3600 spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.

[0543] Chromaticity is calculated according to the equation: C* = +(b*r

[0544] Chromaticity is measured by the values ​​a* and b*, a* representing the red / green axis and b* the yellow / blue axis.

[0545] The higher the value of the chromaticity C*, the more chromatic the color of the treated keratin fibers.

[0546] The results are summarized in Table 3 below:

[0547] [Tables3] Compositions Al (invention) A2 (comparative) a* 41.45 37.32 b* 43.40 42.02 C* 60.01 56.20

[0548] Hair strands treated with composition Al according to the invention exhibit a higher C* value than those treated with the comparative composition A2. In other words, composition Al according to the invention makes it possible to obtain hair strands with improved chromaticity compared to those treated with the comparative composition A2.
