DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye, and more particularly, to a hair dye belonging to an oxidative hair dye,
Fast hair rise, uniform hair dyeing, excellent hair shampoo resistance after hair dyeing, less damage to hair at the time of hair dyeing, giving gloss and moisture to hair after hair dyeing The present invention relates to a hair dye that can be used.

[0002]

2. Description of the Related Art Hair dyes include temporary hair dyes, semi-permanent hair dyes and permanent hair dyes, all of which are widely used for cosmetic purposes.

Among the permanent hair dyes, oxidized hair dyes composed of a first agent containing an oxidation dye (dye intermediate) and a second agent containing an oxidizing agent such as hydrogen peroxide have various colors. It is widely used because it is obtained and has excellent hair dyeing power.

[0004]

However, in the case of an oxidative hair dye, a first agent containing an oxidizing dye and a second agent containing an oxidizing agent are used.
Since the agent is mixed before use and applied to the hair, there is a problem in that it takes more time to develop color on the hair than in the case of an acid hair dye containing an acid dye as a main component, and it is difficult to uniformly dye the hair.

[0005] Oxidative hair dyes generally contain an alkaline agent to promote uniform penetration of the oxidative dye, so that the pH is as high as 10 or more, which is irritating and causes hair to irritate. The protein (protein) component easily leaks out, and the hair is severely damaged at the time of hair dyeing.

Accordingly, the present invention provides a hair dye which has a fast rise time, can be uniformly dyed, has excellent shampoo resistance of the hair after dyeing, and has little damage to the hair at the time of hair dyeing. An object of the present invention is to provide a hair dye capable of imparting gloss and moisture to hair.

[0007]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, have found that animals and plants and / or
Alternatively, when one or more of a microorganism-derived protein hydrolyzate or a derivative thereof is contained in the oxidized hair dye, the hair dyes rise rapidly, can be uniformly dyed, and have excellent shampoo resistance after hair dyeing. The present inventors have found that hair damage during hair dyeing is small, and that the hair after hair dyeing can impart luster, moisture, and good combability to complete the present invention.

[0008] That is, the hair has a damaged part and a healthy part, and this causes a difference in the penetration of the hair dye into the hair, which causes a difference in the hair dyeing speed at the time of hair dyeing and uneven color. In the hair dye of the present invention, it is said that the protein hydrolyzate or its derivative derived from animals and plants and / or microorganisms protects the damaged part of the hair and forms a uniform film including the healthy part. Since it is formed, there is no difference in the penetration of the hair dye, the coloring speed of the hair dye becomes uniform, the degree of hair dyeing becomes uniform, and the occurrence of color unevenness is prevented.

Furthermore, in the hair dye of the present invention, since a protein hydrolyzate or a derivative thereof derived from animals and plants and / or microorganisms sorbs to the hair to protect the hair, the alkaline agent contained in the hair dye and In addition to preventing the hair from being damaged by the oxidizing agent, the hair after dyeing is imparted with luster, moisture and good combability.

Ten panelists were compared and evaluated. The evaluation results of Example 11 are shown in Table 8, and the evaluation results of Example 12 are shown in Table 9. The evaluation results show that the number of persons who answered that the color was darker than Comparative Example 3 and the color that was lighter than Comparative Example 3 The number of people who answered that the color depth was almost the same.

[0068]

[Table 8]

[0069]

[Table 9]

As is clear from the results shown in Table 8, Example 11 in which the quaternary ammonium derivative of hydrolyzed keratin was contained had a treatment time that was half that of Comparative Example 3 which was 1%.
In 5 minutes, many panelists answered that the color intensity was almost the same. The number of persons who answered that the color of the comparative example 3 was darker at the stage of the processing time of 10 minutes was large (that is, the number of persons who answered that the color was lighter than that of the comparative example 3 in Table 8 was large). In Comparative Example 3, the coating was left for 30 minutes after the application of the hair dye, and this was due to the long standing time after the application of the hair dye.

Further, as shown in Table 9, in Example 12 in which the salt of the acylated hydrolyzed collagen was contained, the treatment time was 20 minutes, and almost all of the panelists had almost the same color depth as Comparative Example 3. It is clear that the quaternary ammonium derivative of hydrolyzed keratin (in the case of Example 11) and the salt of the acylated product of the hydrolyzed collagen (in the case of Example 12) shorten the hair dyeing treatment time. It had been.
