Next, the operation of the hair treatment composition will be described.
By containing a keratin component and a cationic surfactant in the hair treatment composition, it is easy to obtain a uniform coating feeling on the hair, and it becomes easy to improve the gloss and smoothness of the hair. The amino acid-based amphoteric surfactant contained in such a hair treatment composition is presumed to improve the dispersibility of, for example, the keratin component while maintaining the function of the cationic surfactant for the hair. That is, the amino acid-based amphoteric surfactant is considered to bring out the function of imparting smoothness to the hair among the functions of the keratin component in the presence of the cationic surfactant. In this regard, in the hair treatment composition containing a keratin component and a cationic surfactant, the inclusion of an amino acid amphoteric surfactant is advantageous.

According to the embodiment described in detail above, the following effects are exhibited.
(1) The hair treatment composition contains at least one keratin component selected from hydrolyzed keratin and cationized hydrolyzed keratin, a cationic surfactant, and an amino acid-based amphoteric surfactant. Thereby, it becomes easy to obtain a uniform coating feeling on the hair, it is easy to improve the gloss of the hair, and it is easy to further improve the smoothness of the hair.

  (2) Since the cationized hydrolyzed keratin is contained as a keratin component in the hair treatment composition, it becomes easy to improve a uniform application feeling and smoothness of the hair.

  (3) The content of the keratin component in the hair treatment composition is 0.01 to 1.5% by mass and the content of the amino acid-based amphoteric surfactant is 0.05 to 5% by mass. The gloss of the hair and the smoothness of the hair are further improved.

(4) The hair treatment composition further contains hydrophobized hydroxyalkyl cellulose, so that it is easy to further improve the gloss of the hair.
(5) When the hair treatment composition further contains a highly polymerized polyethylene glycol, it becomes easy to further improve the uniform coating feeling on the hair.

  (6) Since the hair treatment composition contains at least one of N-alkylaspartic acid and a salt thereof as an amino acid-based amphoteric surfactant, the gloss of the hair can be further improved.

  (7) By incorporating a cationic polymer into the hair treatment composition, for example, the smoothness of the hair can be improved, but when the hair treatment composition is repeatedly applied to the hair, the number of times As a result, the cationic polymer tends to accumulate in the hair. In this regard, according to the hair treatment composition of the present embodiment, it is possible to obtain smoothness of hair without depending on the cationic polymer. Thereby, accumulation | storage to the hair of cationic polymer can be suppressed and the original softness | flexibility which hair has can also be exhibited. From such a viewpoint, when the cationic polymer is contained in the hair treatment composition of the present embodiment, the content thereof is preferably 1% by mass or less, more preferably 0.5% by mass or less, and further Preferably it is 0.1 mass% or less. And hair treatment agent composition can avoid accumulation | storage to the hair of cationic polymer by comprising without containing cationic polymer.

In addition, the said embodiment can also be changed and comprised as follows.
The hair treatment composition can be used for normal hair care, for example, post-treatment of hair damaged by the application of an oxidative hair dye or hair bleach, that is, hair dye treatment or hair bleaching. It may be used for post-treatment of chemical hair treatment such as treatment.

  -A hair treatment agent composition may be divided | segmented into a some agent and comprised. When the hair treatment composition is composed of a plurality of agents, the composition may be applied to the hair after the plurality of agents are mixed at the time of use. It may be used in a mixed manner.

  -The product form of the hair treatment composition may be a color treatment. A color treatment is a hair treatment composition that is gradually dyed to a desired color as a result of repeated hair dyeing treatments, for example, by being applied to hair during routine hair care.

Next, the technical idea that can be grasped from the above embodiment will be described below.

The evaluation results are shown in the “hair gloss” column of Tables 1 and 2.

<Smoothness of hair>
It is judged whether or not the ten professional testers touch the test hair bundle sample to which the hair treatment composition is applied by the method described in <Application of hair treatment composition> above to feel smoothness. did. “5” when the number of testers judged to feel smooth is 9 or more, “4” when 7-8, and “3” when 5-6. “In the case of 3 to 4 people, the evaluation was made in 5 stages,“ 2 ”, and in the case of 2 or less people,“ 1 ”. The evaluation results are shown in the column “Smoothness of hair” in Tables 1 and 2.

As shown in Table 1, each example contains (A) a keratin component, (B) a cationic surfactant, and (C) an amino acid-based amphoteric surfactant. It can be seen that an evaluation result of “3” or more is obtained for each of “Gloss of hair”, “Smooth hair”, and “Smoothness of hair”.

  As shown in Table 2, in Comparative Example 1, since (C) the amino acid-based amphoteric surfactant was not contained, the evaluation result of “smoothness of hair” was inferior to each example. In Comparative Example 2, since the (A) keratin component is not contained, the evaluation result of “uniform coating feeling” is particularly inferior to each example. In Comparative Example 3, since (B) the cationic surfactant is not contained, the evaluation result of “uniform coating feeling” is inferior to each Example.
