Composition for the oxidative dyeing of keratin fibers

The present invention relates to a composition for oxidative staining of keratin fibers containing conchiolin protein. More specifically, in the composition for oxidation dyeing, which comprises a first agent containing an oxidizing dye precursor and a second agent containing an oxidizing agent, by containing the conchiorine protein in the first agent, the hair gloss and Keep it glossy.

Generally, hair dyes are classified into permanent hair dyes, semi-permanent hair dyes and temporary hair dyes according to the degree of hair dyeing. Among the hair dyes, permanent hair dyes are formed by oxidative coupling reactions between pigments by oxidizing dyes or direct dyes, alkalis, oxidants, etc., and the pigments passing through the hair cuticle to the hair cortex. This is the principle. In the process, the alkali agent plays a role of widening the gap of the cuticle, and the oxidant plays a role of initiating the oxidative coupling of the pigment. The permanent hair dye is superior in color persistence as the pigment reaches the cortex as compared to the semi-permanent hair dyes and temporary hair dyes and currently occupies most of the hair dye. However, the permanent hair dye is recognized as hair damage after dyeing by keratin oxidizing the pigment under the influence of the oxidizing agent used together and swelling of the cuticle caused by the alkaline agent, resulting in hair damage after dyeing. Its gloss and gloss have been significantly reduced, degrading its value as a cosmetic. In addition, some colors, especially in the case of mauve light has a technical limitation in improving the shortcomings because the color persistence is about two weeks.

Therefore, the present inventors have studied to solve the disadvantages of the conventional permanent hair dye that the hair gloss and gloss is lowered after dyeing while maintaining the color for a certain time, when using the conchiorine protein in the hair dye, even after dyeing It was found that the gloss lasted and that the color persistence was also excellent and completed the present invention.

Accordingly, it is an object of the present invention to provide a composition for oxidative dyeing of keratin fibers containing conchiolin protein.

In order to achieve the above object, the composition for oxidation dyeing keratin fibers according to the present invention is characterized in that it contains a conchiolin protein in an amount of 0.001 ~ 15.0% by weight relative to the total weight of the composition.

The composition for oxidation dyeing of keratin fibers of the present invention comprises a first agent containing an oxidizing dye precursor and a second agent containing an oxidizing agent, which contains conchiorine protein in the first agent and exhibits excellent color persistence, and thus hair after dyeing. To maintain the shine and luster of the hair.

Conchiorine protein used in the present invention is a protein derived from pearls, and especially a protein contained in the mineral of the pearl shell, and is a component closely related to the reflection, diffraction and absorption of light, which are basic properties of gloss and gloss. In the present invention, the conchiolin protein is a raw material in powder or liquid form including hydrolyzed conchiolin protein (CTFA Name: Hydroxyzed Conchiolin Protein) or conchiolin powder (CTFA Name: Conchiolin Powder). In the case of keratin fibers treated with a dye containing the conchiorin protein, the conchiorin protein penetrating the cuticle and the medulla is present with an oxidizing dye or a direct dye, affecting the reflection, absorption and diffraction of light, resulting in gloss and It gives gloss. In addition, it serves to help retain the pigment of the paraamino orthocresols expressing purple to maintain the color for a certain time.

In the present invention, the conchiolin protein is contained in an amount of 0.001 to 15.0% by weight based on the total weight of the composition. If it is less than 0.001% by weight, no effective effect can be obtained, and if it exceeds 15.0% by weight, color development is inhibited, so it is preferable to use it within the above range.

On the other hand, the oxidizing dye precursors contained in the first agent of the oxidizing dye composition according to the present invention is paraphenylenediamine, paraaminophenol, toluene-2,5-diamine, 2-chloro-para-phenylenediamine, N, N-dimethylparaphenylenediamine, N, N-bis (2-hydroxyethyl) -paraphenylenediamine, 2,4-diaminophenol, paramethylaminophenol, orthochloroparaphenylenediamine And acid addition salts thereof. The oxide dye precursor is used in 0.001 to 5.0% by weight based on the total weight of the composition.

The first agent may also contain direct dyes, alkalines and colorants.

As the direct raw material, nitroparaphenylenediamine, 2-amino-4-nitrophenol, 2-amino-5nitrophenol, paranitrometaphenylenediamine and acid addition salts thereof may be used. The direct raw material is used in 0.001 to 5.0% by weight based on the total weight of the composition.

In addition, the alkali agent used in the present invention includes ammonia water or monoethanolamine, and is used at 0.1 to 20% by weight based on the total weight of the composition.

In addition, as a coloring agent used in the present invention, resorcinol, 2,4-diaminophenoxyethanol, paraaminoorthocresol, metaaminophenols, metaphenylenediamines, diaminopyridines, dihydroxynaphthalene And derivatives thereof. The coloring agent is contained in 0.001 to 5.0% by weight based on the total weight of the composition.

On the other hand, as the oxidizing agent contained in the second agent of the oxidation dye composition according to the present invention, it is preferable to use hydrogen peroxide, the content of which is used at 6.0% by weight based on the total weight of the composition.

Hereinafter, although an Example and a comparative example are given and this invention is demonstrated in detail, this invention is not limited only to these examples.
