Description

  The invention disclosed in the present application relates to a harshness imparting agent composition. More specifically, the present invention relates to a firmness-imparting agent composition capable of imparting firmness and stiffness to hair that has lost its firmness and stiffness as a result of aging, while born, or due to damage caused by chemical or physical treatment.

  As hair ages, the hair roots weaken, and newly grown hair grows thin and soft and loses its elasticity and stiffness. In addition, the hair may be thin as it is born, and there may be no firmness or stiffness. In addition, when a chemical treatment such as hair coloring or permanent treatment is applied, proteins inside the hair flow out of the hair. Losing the protein in the hair will make the hair thinner and lose elasticity and stiffness. In addition, physical treatment such as brushing also damages the hair, and the hair loses its elasticity and stiffness as in the case described above.

  Therefore, it has been attempted to give hair elasticity by coating the hair with a coating agent such as a polymer (Patent Document 1). In addition, hair quality improving agents and hair growth agents that act on hair matrix cells that produce hair to improve the elasticity and stiffness of newly created hair are known (Patent Documents 2 and 3). Attempts have also been made to improve hair feel and the like (Patent Document 4).

  According to the invention described in Patent Document 1, a polymer having a cross-linked structure is applied to hair, and the hair surface is coated to coat the hair surface, thereby imparting firmness to the hair having no firmness that appears as a characteristic phenomenon of aging with aging changes. can do. However, when the hair is coated, it is washed away with a shampoo or the like, so that it can be temporarily applied, but has not yet reached a fundamental solution.

  According to the invention described in Patent Document 2, the hair quality can be improved by improving the firmness and stiffness of newly created hair by directly acting the eucalyptus extract on the hair matrix cells. Generally, a hair restorer is applied to the scalp and hairline, and the target on which the hair restorer acts is a living cell such as a hair matrix cell. Therefore, it will be a fundamental solution for newly produced hair, but it will be applied again to untreated hair that has already grown and hair that has lost its elasticity and stiffness due to chemical and physical damage. Cannot be granted.

  According to the invention described in the above-mentioned Patent Document 3, a hair-growth / hair-restoration effect and a hair feel-improving effect can be obtained by applying a hair-restoring agent containing a oyster extract as an essential component to the scalp or hairline (Patent Document 3 test) 5). From the application method in the test, the target of the hair restorer is a living cell as in the case of the hair restorer described in Patent Document 2.

  According to the invention described in Patent Document 4, cuticle lift-up suppression, moisture retention, and hair cohesion can be improved by applying a cherry extract to the hair. These effects were confirmed by the test results of the cherry “flower” extract. As the test results show, the invention described in Patent Document 4 gives a moist and moist feeling to the hair, and therefore cannot give the hair firmness and firmness.

  Therefore, the inventor of the present application searched for a component capable of imparting elasticity and stiffness to hair that has lost elasticity and stiffness as a result of aging or birth, or due to damage caused by chemical or physical treatment. As a result, it has been found that application of an extract of cherry “leaves” to the hair shaft can impart elasticity and stiffness to the hair shaft.

  In the present application, the “hair shaft” refers to a portion of hair that is exposed from the scalp to the outside of the body. The hair shaft is composed of dead cells.

  Therefore, it is an issue to be solved by the present application to provide a firmness-imparting agent composition that imparts firmness and stiffness to hair by application to the hair shaft. In addition, it is an object of the present application to provide a hair treatment composition capable of imparting elasticity and stiffness that can be applied to various uses.

(First invention)
The configuration of the first invention of the present application for solving the above problems is as follows.
It is a harshness imparting agent composition containing a cherry extract and applied to the hair shaft.

(Second invention)
The configuration of the second invention of the present application for solving the above problem is as follows.
It is a harshness imparting agent composition according to the first aspect of the invention, containing 0.01 to 0.25% by mass of the cherry extract.

(Third invention)
The configuration of the third invention of the present application for solving the above problem is as follows.
It is a hair treatment agent composition containing the sharpening agent composition as described in 1st invention or 2nd invention. That is, if a hair shaft becomes an application object, a use will not be limited.

(Fourth invention)
The configuration of the fourth invention of the present application for solving the above problem is as follows.
The hair treatment composition according to the third aspect of the present invention, wherein the use of the hair treatment composition is hair lotion, hair shampoo, hair treatment, decoloring / destaining agent, oxidative hair dye, permanent agent, or hair dye. It is a thing.

(Fifth invention)
The configuration of the fifth invention of the present application for solving the above problem is as follows.
It is a hair treatment set which contains the composition in any one of 1st invention-4th invention in a structure.

(First invention and second invention)
According to the first and second inventions of the present application, an excellent sharpening agent composition is provided. If the firmness imparting agent composition of the first or second invention of the present application is applied to the hair shaft, it is presumed that the cherry extract can permeate into the hair shaft of the hair, thereby imparting elasticity or stiffness to the hair. In particular, the second invention realizes a more preferable degree of elasticity applied to the hair.

Below, the difference between the sharpening agent composition and the hair restorer according to the first and second inventions will be described.
It is a hair shaft to which the harshness imparting agent composition is applied, and the hair shaft is composed of dead cells. On the other hand, hair restorers target living cells. That is, the state of application object is completely different between the above-mentioned harshness-imparting agent composition and the hair restorer.

  The firmness imparting agent composition can impart firmness and stiffness to untreated hair that has already grown and to hair that has lost firmness and stiffness due to chemical and physical damage. On the other hand, the hair growth agent can be a fundamental solution for newly produced hair, but the effect exhibited by the above-mentioned harshness-imparting agent composition cannot be obtained.

  Further, Table 3 of Patent Document 3 discloses that even if the cherry extract is applied to the scalp alone, the effect of improving hair feel is hardly obtained (9 out of 10 testers are judged invalid). ing.).

Below, the difference between the sharpening agent composition according to the first invention and the second invention and the invention described in Patent Document 4 will be described.
Even if the cherry blossom extract is applied to the hair shaft, the hair cannot be given firmness or stiffness (provided in Comparative Example 1 described later). Therefore, the effect exerted by the harshness-imparting agent composition obtained using the cherry leaf extract is different from the effect described in Patent Document 4.

  Furthermore, as described in Patent Document 4, when the cherry blossom extract is applied to the hair, a moist feeling and softness are imparted, and on the contrary, it prevents the firmness and stiffness from being imparted to the hair. If it aims at giving elasticity and stiffness to hair, the effect of the invention of the above-mentioned patent documents 4 will be lost. In other words, Patent Document 4 does not disclose or suggest a technique for applying elasticity to the hair shaft or such a problem. Patent Document 4 does not disclose any examples or comparative examples using cherry leaf extract.

(3rd invention and 4th invention)
According to the third invention of the present application, an excellent hair treatment composition is provided. In addition to the original effects of the hair treatment composition, it is considered that the hair can be further provided with firmness and stiffness. According to the fourth invention of the present application, even if the cherry extract is added to a hair lotion, a hair shampoo, a hair treatment, a decoloring / destaining agent, an oxidative hair dye, a permanent agent, or a hair dye, these hair treatment compositions are produced. In addition to the original effect, it is possible to impart firmness and stiffness to the hair.

(Fifth invention)
According to the fifth invention of the present application, an excellent hair treatment set is provided. The convenience of the harshness-imparting agent composition and the hair treatment agent composition is further improved.

  Hereinafter, embodiments of the invention disclosed in the present application will be described including the best mode.
