Description

  The present invention relates to an oxidant composition. More specifically, the present invention relates to an oxidant composition that can effectively prevent loss of elasticity due to internal damage of hair seen during treatment of oxidant to hair and reduction of hair volume during styling based on the loss.

  As is well known, hyaluronic acid is a linear polymer acidic mucopolysaccharide consisting of repeating disaccharide units in which glucuronic acid and N-acetylglucosamine are glycosidically linked, and having a molecular weight of several hundred thousand to several million daltons. It is distributed in each part of the living body. And since hyaluronic acid has the capability to couple | bond with a lot of water | moisture contents, it is often mix | blended with various hair treatment agents as a moisturizing component. Moreover, from the characteristic as a polysaccharide, it is mix | blended also for the purpose of the hair damage countermeasure in a general meaning.

[Patent Document 1] Japanese Patent Application Laid-Open No. S59-110612 Patent Document 1 discloses hyaluron as a hair treatment agent for hair treatment, hair conditioner, hair spray, set lotion and the like for the purpose of recovering damaged hair and giving gloss to hair. It discloses that an acid or a salt thereof is added.

JP 2005-517051 JP Patent Document 2 discloses an amphoteric polysaccharide carrying a cation group and an anion group via a CN covalent bond, and this amphoteric polysaccharide is used for hair conditioning and the like. The composition for dyeing and decoloring hair blended is defined in claim 10. Although hyaluronic acid is mentioned as a kind of polysaccharide, it is not clear how cationic groups and anionic groups are supported on hyaluronic acid via CN covalent bonds.

Japanese Patent Application Laid-Open No. 64-56611 discloses a hair dye composition containing a mucopolysaccharide such as hyaluronic acid. As the hair dye composition, an oxidation dye intermediate is a main ingredient. A two-component hair dye composition comprising a first agent and a second agent mainly composed of an oxidizing agent is mentioned. In addition, as an effect of blending mucopolysaccharide, “improvement of dyeability of hair dye” and “prevention of hair damage” are mentioned.

  However, according to the study of the present inventor, even when hyaluronic acid is added to the oxidizer composition, it can be expected to have a moisturizing effect. It has been found that there is a problem that the hair cannot be sufficiently prevented and a hair bundle feeling is produced in the finished hair. “Feeling of hair bundles” refers to excessive cohesion between hairs when hand combs are passed through the hair, and the hairs are bundled in units of dozens of units along the part through which the hand combs are passed. It gives a streak-like appearance and feel. It is not preferable to produce a feeling of hair bundle after using the hair cosmetic.

  Therefore, the present invention, when hyaluronic acid is blended in the oxidizer composition, while ensuring its original moisturizing effect, etc., while ensuring the firmness of the hair at the finish and preventing volume reduction, Preventing the occurrence of this is a technical problem to be solved.

  In the process of studying the means for solving the above-mentioned problems, the present inventor is effective to use a cationized hyaluronic acid having a specific structure that is unusual as a hyaluronic acid compounded for such a purpose, and to further combine an aromatic alcohol.

As a hair sample for evaluation, a hair wig having a straight and voluminous volume was used. For this hair wig, the first agent and the second agent of the oxidative hair dye according to each of the comparative examples and examples described above were mixed and prepared at a mass ratio of 1: 2, and each was processed in a conventional manner, and thereafter Washed with water. These hair wigs were evaluated as follows.
(Hair volume increase)
About the hair wig which concerns on each example dried after said process, the volume feeling of hair was evaluated by visual observation. In this evaluation, the case of Comparative Example 1 was used as a control, and compared with this, it was evaluated as “degree of increase in hair volume”. There were four evaluation criteria. That is, in contrast to the control, the case where the volume of the hair is sufficiently increased is `` ◎ '', the case where it is not sufficient but increased is `` ○ '', the case where it is equivalent to the control is `` △ '', The case where the volume was lower than the control was indicated as “x”. The results of these evaluations are shown in Table 1.
(Hair bundle feeling)
A hand comb was passed through the hair wig according to each example dried after the above treatment, and it was determined by visual observation whether or not a hair bundle sensation was produced. The evaluation criteria for the feeling of hair bundle are “◎” when no hair bundle feeling is recognized, “○” when slightly hair bundle feeling is recognized, and “△” when slightly clear hair bundle feeling is recognized. According to the four-step evaluation, the case where the hair bundle feeling was recognized as “x”. The results of these evaluations are shown in Table 1.
(Moisture retention of hair)

And the hair wig weight at the time of completion of these 1st-3rd steps was precisely weighed, respectively. The hair wig weight at the completion of the first step is “H1”, the hair wig weight at the completion of the second step is “H2”, and the hair wig weight at the completion of the third step is “H3”. Separately, as a control, the same hair wig was washed with water instead of being treated with the hair cosmetic composition, and the above first to third steps were performed to obtain “H1” to “H3”.

  For each example, comparative example, and control, the amount of water “HW1” of the hair wig at the time of completion of the first step is calculated by the calculation of “H1−H3”, and the amount of water at the time of completion of the second step is calculated by the calculation of “H2−H3”. The moisture content “HW2” of the hair wig was determined. And about each Example and the comparative example, HW2 was compared with the case of control.

Specifically, with respect to the amount of water in the case of control (the index value of absolute amount is “100”), the index value is 110 or more, “◎”, and the index value is 105 or more and less than 110. Moisture retention of hair was evaluated by a four-step evaluation, where “◯”, index value of 101 or more and less than 105 was “Δ”, and index value of less than 101 was “x”. The results of these evaluations are shown in Table 1.
(As per finger after finishing)
About the hair wig which concerns on each example dried after said process, the finger passage was evaluated. Evaluation criteria are “◎” when the finger passage is very good, “○” when the finger passage is good, “△” when the finger passage is slightly bad, and “×” when the finger passage is bad. Is a four-step evaluation. The results of these evaluations are shown in Table 1.

  According to the present invention, an oxidant composition capable of preventing the generation of a hair bundle feeling at the finish while securing the hair's elasticity and preventing the hair volume from being lowered while ensuring the excellent moisturizing effect of the hair, etc. Provided.
