Description

  The present invention relates to a hair cosmetic composition. More specifically, the present invention can effectively prevent a specific problem that occurs in the case where a silicone compound having a different kinematic viscosity is combined with a hair cosmetic composition while maintaining an excellent effect. The present invention relates to a hair cosmetic composition that can be used.

As is well known, when a silicone compound is blended in various hair cosmetic compositions, it is possible to impart smoothness, smooth feel, gloss, etc. to the hair. In particular, in recent years, research on the compounding effect of silicone compounds has progressed, and when two types of silicone compounds with greatly different kinematic viscosities or molecular weights are blended together, smoothness, flexibility, smooth feel, etc. are particularly excellent for hair. It has been found that the effect can be sustained.
(Patent Document 1) Japanese Patent Application Laid-Open No. 6-80538 Patent Document 1 discloses a high molecular weight silicone compound having a siloxane bond (Si—O—Si) structure as component (A) and a similar siloxane as component (B). Hair cosmetics each containing a low molecular weight silicone compound having a binding structure are disclosed. In the Examples section of the specification, it is seen that such hair cosmetics give the hair smoothness, flexibility, smoothness and moistness.
(Patent Document 2) Japanese Patent Application Laid-Open No. 2007-320876 In Patent Document 2, (A) dimethiconol having a kinematic viscosity of 5,000 mm ² / s or less at 25 ° C. and (B) kinematic viscosity at 25 ° C. of 100,000 mm. A hair treatment composition containing ² / s or more of dimethiconol at a constant mass ratio is disclosed. In the Examples section of the specification, it is seen that such a hair treatment composition gives the hair a cuticle peeling prevention effect, softness, ease of grouping, and suppleness.

  However, according to the research of the present inventor, for example, when hair is treated with a hair cosmetic compounded together with silicone compounds having greatly different kinematic viscosities or molecular weights as in Patent Document 1 and Patent Document 2, the hair has smoothness, Softness, a smooth feel, and the effect lasts, but if the moist feeling immediately after treatment is lost as the hair dries, (a) Unnatural oily feeling that is unique to silicones It was found that (b) and the gloss of the silicones persists more than necessary with the result of (a), giving an unnatural feeling. These defects (a) and (b) were particularly remarkable in hair that was strongly damaged.

  Therefore, the present invention should solve the problems such as (a) and (b) described above while maintaining the excellent effects of the hair cosmetics containing silicone compounds having different kinematic viscosities. Technical issue.

  The inventor of the present application focused on the balance between moisture and silicone on the hair in the course of studying the solution to the above problem. That is, it was thought that if the moisture balance was properly maintained on the hair after the treatment with the hair cosmetic until after the hair was dried, an unnatural oily feeling and a glossy unnaturalness could be prevented. As a means for continuously realizing a good balance between moisture and silicone on the hair, it was found that cationized hyaluronic acid having a specific chemical structure is suitable, and the present invention has been completed.

(First invention)
The structure of the 1st invention of this application for solving the above-mentioned subject is a hair cosmetics composition which blended the following (A) ingredient-(C) ingredient.
(A) Cationized hyaluronic acid in which the carboxyl group of glucuronic acid constituting hyaluronic acid is modified with a quaternary ammonium-containing modifying group, or at least a part of functional groups other than the carboxyl group in this cationized hyaluronic acid At least one selected from cationized hyaluronic acid analogs that have undergone at least one of salt formation and modification.
(B) At least one selected from silicone compounds having a kinematic viscosity at 25 ° C. of 100 mm ² / s or less.
(C) At least one selected from silicone compounds having a kinematic viscosity at 25 ° C. of 50,000 mm ² / s or more.

(Second invention)
The configuration of the second invention of the present application for solving the above-described problem is that the quaternary ammonium-containing modifying group in the component (A) according to the first invention is at least a bond between the quaternary ammonium and the carboxyl group. It is a hair cosmetic composition which is an organic group provided with the provided hydroxyl group.

(Third invention)
In order to solve the above-mentioned problem, the third invention of the present application is such that the cationized hyaluronic acid according to the first invention or the second invention comprises a repeating unit represented by the following “formula 2” formula, A hair cosmetic composition wherein the hyaluronic acid analog is one in which at least a part of the hydroxyl group and N-acetyl group of the repeating unit represented by the formula 2 has undergone at least one of salt formation and modification. is there.

(Fourth invention)
The structure of the fourth invention of the present application for solving the above problems is that the hair cosmetic composition according to any one of the first to third inventions is provided in any one or both of the following (1) and (2): It is a hair cosmetic composition which is applicable.
(1) The component (B) is at least one selected from dimethicone, cyclomethicone, diphenyl dimethicone and aminopropyl dimethicone.
(2) The component (C) is at least one selected from dimethicone, dimethiconol and aminopropyl dimethicone.

  Since the hair cosmetic composition according to the first aspect of the invention contains both the component (B) and the component (C), a good balance regarding the kinematic viscosity of these silicone compounds (this balance is hereinafter referred to as “silicone balance”). ”), It gives the hair smoothness, flexibility, and a smooth feel, and their effects are sustained. These effects can be confirmed as, for example, the goodness of the hair and the softness of the hair. Moreover, since the cationized hyaluronic acid having a specific chemical structure as the component (A) is blended, an unnatural oily feeling as pointed out in the above (a) and (b) while maintaining the above effect. Unnaturalness of gloss and gloss can be continuously prevented until after the treated hair is dried. Such a blending effect of the component (A) is presumed to be due to the following reason.

  That is, the cationized hyaluronic acid having a specific chemical structure as the component (A) and its analogs have an ability to bind to a large amount of moisture, and thus have an excellent moisturizing effect, and have good moisture and silicone on the hair. A good balance. Furthermore, this cationized hyaluronic acid has a tendency to have negatively charged hair (strongly damaged hair) because the carboxyl group of glucuronic acid constituting hyaluronic acid is cationized by a quaternary ammonium-containing modifying group. Shows a strong adsorptive property against a particularly large negative charge). Therefore, the component (A) ensures a moist feeling of the hair after treatment with the hair cosmetic (a good moisture balance on the hair), and the effect lasts long after the hair is dried. As a result, there is no fear of losing the moist feeling associated with the drying of the hair, and it is possible to prevent the silicones from giving an unnatural oily feeling with a unique squeaky feeling and an unnatural feeling of gloss. Moreover, from the mechanism of action of the component (A), effects such as good fingering and softness of the hair based on the blending of the components (B) and (C) are not inhibited.

  It is known that hyaluronic acid is used as a moisturizing component in the field of hair cosmetic compositions, but these do not show strong adsorptivity to hair because they are not appropriately cationized. The effect is not expected.

  In the quaternary ammonium-containing modifying group in component (A), the type of functional group chemically bonded to the carboxyl group of glucuronic acid is not particularly limited, and may be, for example, an amino group or the like. Thus, it is more preferable that this functional group is a hydroxyl group.

  Further, as in the third invention, the cationized hyaluronic acid has a repeating unit represented by the formula “Chemical Formula 2”, and the cationized hyaluronic acid analog has a cationized hyaluronic acid represented by the Formula “Chemical Formula 2”. Particularly preferred are those in which the hydroxyl group or N-acetyl group is salt-formed or modified.

"Is inferior.

  In Comparative Example 5 in which the component (B) is not blended, the silicone compound is quantitatively compensated by increasing the blending amount of the component (C) in contrast to the same Comparative Example 4. . Further, in Comparative Example 9 in which the component (C) is not blended, the silicone compound is quantitatively compensated by increasing the blending amount of the component (B) in comparison with Comparative Example 8 which is the same. . However, such quantitative compensation results in further breaking the silicone balance. That is, the comparative example 5 is not compared with the comparative example 4, and the comparative example 9 is not compared with the comparative example 8, and the evaluation of each item is not improved or rather worsened.
