Description

  The present invention relates to a hair cosmetic composition. More specifically, the present invention relates to a hair cosmetic that can effectively prevent a specific problem that occurs in that case while maintaining an excellent effect when a specific oil is blended in the hair cosmetic composition. Relates to the composition.

As is well known, when an oil component is blended in various hair cosmetic compositions, it is generally possible to impart smoothness, luster, moist feeling and the like to the hair. In recent years, for example, as seen in Patent Document 1 below, the oily component is semisolid in a temperature range slightly higher than room temperature, and liquid in a temperature range slightly higher than that. Attention has been given to hair cosmetic compositions containing such oils.
(Patent Document 1) Japanese Patent Application Laid-Open No. 2001-139437 In Patent Document 1, together with a cationic surfactant, a higher alcohol, and a specific silicone compound, “a paste at 20 ° C. and a melting point of 30 ° C. to 55 ° C. The hair rinse composition which mix | blended predetermined amount with "the oil agent which has" is disclosed. In the Examples section of the specification, it is seen that this composition gives good hair mass, moisture, gloss, and combability to the hair.

  However, according to the research of the present inventor, for example, when hair is treated with a hair cosmetic compounded with a specific oil as disclosed in Patent Document 1, the hair is smooth, combed, glossy, soft on the hair. It was found that the following problems are involved, although it is possible to give a unity. That is, such an oil agent has a high water repellency, but under high humidity, the hair becomes excessively hydrated, and depending on the hair quality, a sticky oily feeling or a glare and unnatural luster may be generated. Such a defect is also observed immediately after the hair is treated, but the defect may become more prominent with the passage of time thereafter.

  Therefore, the present invention maintains a sticky feeling due to excessive hydration of hair and expression of glare and unnatural luster while maintaining the excellent effects of the hair cosmetics containing the specific oil as described above. Preventing this is a technical problem to be solved.

  In the process of studying the solution to the above problem, the present inventor preferably uses cationized hyaluronic acid having a specific chemical structure as a means of preventing excessive hydration of hair (that is, deterioration of hair moisture balance). As a result, the present invention was 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 and (B) 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 semisolid oils at 25 ° C.

(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)
In the fourth aspect of the present invention for solving the above problem, the component (B) according to any one of the first to third aspects of the present invention is at least one selected from hydrocarbons, fatty acid esters, animal oils and vegetable oils. A hair cosmetic composition.

(Fifth invention)
In order to solve the above-mentioned problem, the fifth invention of the present application is such that the component (B) according to any one of the first to fourth inventions is petrolatums, dimer acid esters, dimer diol esters, pentaerythritol esters. , A hair cosmetic composition that is at least one selected from fatty acid sterol esters, lanolins and plant-derived triglycerides.

  Since the hair cosmetic composition of the first invention is blended with the component (B), it imparts smoothness, combability, gloss, a soft unit of hair, etc. to the hair, as in the prior art. be able to. These effects can be confirmed, for example, as the goodness of the fingers and the softness of the hair. In addition, since the cationized hyaluronic acid having a specific chemical structure as the component (A) is blended, unnatural oiliness and unnatural glossiness can be prevented in the hair while maintaining the above effects. . The reason why such a blending effect of the component (A) is obtained cannot always be stated decisively, but it is presumed that it is as follows.

  That is, the cationized hyaluronic acid having a specific chemical structure as the component (A) or an analog thereof exhibits an excellent moisturizing effect of maintaining an appropriate water balance based on its water binding ability. In addition, since the carboxyl group of glucuronic acid constituting hyaluronic acid is cationized by a quaternary ammonium-containing modifying group, hair that tends to have negative charge (strongly damaged hair has particularly high negative charge) Strong adsorptivity to As a result, with respect to the moisture balance on the hair, the action of the cationized hyaluronic acid as the component (A) is dominant or preferential over the action of the oil agent as the component (B). It is realized and hair hydration based on oil is prevented. Therefore, it can be considered that an unnatural oily feeling and unnatural glossiness in the hair do not appear. Moreover, from the mechanism of action of the component (A), effects such as good fingering and softness of the hair based on the formulation of the component (B) 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.

  Further, the oil agent as the component (B) is not limited as long as it matches the definition of the component (B) in the first invention, but examples thereof include hydrocarbons, fatty acid esters, animal oils and vegetable oils listed in the fourth invention, More specifically, for example, various compound groups listed in the fifth invention can be mentioned.
