Description

FIELD OF THE INVENTION [0001] The present invention relates to a first agent for oxidative hair dyeing,

The present invention relates to a first agent for an oxidation hair dye containing an oxidation dye and to an oxidation hair dye containing the first agent and a second agent for the oxidation hair dye.

The oxidation dyeing agent used for coloring the hair is dyed (dyed) by oxidative polymerization with the oxidation dye penetrated into the hair. The oxidative dyeing agent maintains the color retention of the hair for a long period of time in comparison with other hair-coloring agents such as an acid salt dye. It is known that the oxidation dyeing agent is different in color by the selection and combination of oxidation dyes. When the dye intermediate, p-aminophenol, and the coupler, 5-aminoorthocresol, are combined, the oxidation dyeing agent develops orange color. Patent Document 1 and Patent Document 2 disclose oxidation hair dye containing para-methylaminophenol in addition to the oxidation dye of the combination (see paragraph 0074 of Patent Document 1 and paragraph 0078 of Patent Document 2).

[ Example ]

Hereinafter, the present invention will be described in more detail with reference to examples. However, the present invention is not limited to the following examples unless it departs from the gist of the present invention.

(First agent)

A first agent of Examples, Comparative Examples and Reference Examples in which a first agent of the oxidation dye concentration shown in Tables 1 to 3 shown below was compounded in water was prepared. In addition to the oxidation dyes shown in Tables 1 to 3, the first agent contained 1.2% by mass of 25% by mass ammonia water, 0.09% by mass of ethylenediaminetetraethylhydroxyethylphosphate triacetate dihydrate, 0.15% by mass of L-ascorbic acid, Sodium sulfite was added so as to be 0.3% by mass.

(Second)

A common second agent for mixing with the first agent to obtain an oxidative dyeing agent was formulated into water such that the amount of 35 mass% hydrogen peroxide was 5.7 mass% and that of hydroxyethane diphosphonic acid was 0.12 mass%.

(Oxidative dyeing agent)

The prepared first agent and second agent were mixed at a mass ratio of 1: 1 to obtain an oxidative dyeing agent.

(Hair treatment)

Two bundles of hair ("BM-YK" manufactured by Burakx Co., Ltd .: about 1 g, yamamomo speed of about 10 cm) were placed in a glass tube together with 60 g of an oxidative dye and allowed to stand at room temperature for 20 minutes. Thereafter, the oxidation dyeing agent was washed away from the mother liquor with hot water, and dried with warm air while combing the mother liquor. As a result, the hair was treated.

(Hydrochloric acid)

The concentration of the orange color was visually confirmed with respect to the standard hair growth rate (based on Comparative Example 1c in Table 1, and Comparative Example 2b in Table 2). The evaluation criteria were as follows.

○: The concentration of orange color equivalent to the parental standard of "standard".

X: The orange color is blurred than the parental speed based on the "reference".

(Shampoo treatment)

One cornstarch treated with a hair treatment was immersed in a glass container together with an aqueous solution of 80 g of 3 mass% shampoo (DEESSE'S NEU WillowLuxe). Then, the glass container containing the mother liquor was shaken at 40 DEG C for 30 minutes using a constant-temperature shaker. After that, the shampoo was washed from the mother liquor by hot water, and dried with warm air while combing the mother liquor. The brightness L * of the dried hair was measured three times while changing the measurement site using a spectroscopic colorimeter ("CM-600d" manufactured by Konica Minolta Sensing Co., Ltd.), and the average value of the lightness L * was calculated.

(Daylight exposure)

The groups 1, 2, 2, and 2 of the Tables 1a to 1c and Comparative Examples 1a to 1c, and the Groups 1 and 2 of the Reference Examples 1 to 2 were separately exposed under daylight. The exposure conditions at this time were set aside for seven days with the naked eye attached to the window glass of the room. The average value of the lightness L * of the hair after the exposure was calculated to be the same as the average value after the shampooing treatment.

The evaluation results of the hydrochloric acid resistance and the light fastness are shown in Tables 1 to 3 together with the dyes blended. "ΔL *" in the table is a value calculated by "(brightness L * of the hair after shampooing treatment or exposure to sunlight) - (brightness L * of the hairless hairless amoebus)". The "ΔL * ratio (after sunlight exposure / after shampooing") is a ratio of ΔL * after exposure to sunlight to ΔL * after shampooing. The larger the value is, the less discolored (excellent in light fastness) .

In Table 1, since the? L * ratio of Examples 1a to 1c containing paramethylaminophenol is higher than that of Comparative Example 1c which does not contain para-methylaminophenol, the combination of paramethylaminophenol, Can be improved. Further, Examples 1 a to 1c having a para-methylaminophenol content / para-aminophenol content (PMAP / PAP content) of less than 0.20 are superior to Comparative Examples 1a to 1b having PMAP / PAP of not less than 0.20, Is less than 0.20, it can be understood that it is important to darken the orange color.

In Table 2, as in Table 1, it is confirmed that the improvement of the light fastness according to the inclusion of paramethylaminophenol and the superiority of the deep orange coloring (the superiority of dyeing with deep orange color) due to the PMAP / PAP of less than 0.20 .

In Table 3, the? L * ratio is higher than that of Reference Example 1 in Reference Example 2. This indicates that even in the case of Reference Example 1 in which 5-aminoorthocresol was not compounded as a coupler, the light-fastness was not improved even when p-methylaminophenol was added.
