Description

  The present invention relates to a cosmetic that can be used on hair and skin to protect hair and skin from ultraviolet light.

  In recent years, there has been an increasing tendency to pay attention to the adverse effects of ultraviolet light on skin and hair, and UV absorber-containing cosmetics for application to the skin and UV absorber-containing hair cosmetics for application to the hair are known ( For example, refer to Patent Document 1 and Patent Document 2). Therefore, if there is a UV absorber-containing cosmetic that can be applied to both skin and hair, care for UV protection can be simplified.

  However, while the texture required for cosmetics for the skin is a texture such as no stickiness and familiarity with the skin, the texture required for a cosmetic for hair is such as softness of the hair and fingering of the hair It was difficult to obtain a cosmetic with a texture that satisfied both.

  Known cosmetic compositions which can be applied to both skin and hair include hair and body oils including low viscosity ester oils, volatile hydrocarbon oils, vegetable oils, non-volatile oils and low viscosity silicones (eg, patent Reference 3).

  However, the cosmetic described in the example of Patent Document 3 contains 12% by weight of non-volatile hydrocarbon. Such a large amount of non-volatile hydrocarbon may cause stickiness to the hair and skin depending on the formulation.

  In addition, Patent Document 3 describes that the UV absorber may be further contained, but the amount of the UV absorber specifically described is 0.1% by weight or less, and generally UV protection is carried out. Much less than formulated in the targeted cosmetic. When a cosmetic containing a UV absorber in an amount to fulfill the purpose of UV protection is applied to the hair, the hair may become squeezed or squeaky, and the goodness of the fingerness of the hair can not be obtained.

  It can be seen from Table 1 that when the content of the component (A) is less than the range of the present invention, the protective effect against ultraviolet light can not be obtained, and neither skin moisture nor softness of the hair can be obtained. When the content of the component (A) is more than the range of the present invention, the protective effect against ultraviolet rays is sufficient but it causes stickiness on the skin and the hair, and the softness of the hair, poor finger passing and poor cohesion, cosmetics You can see that the familiarity with the skin is also bad.

  Referring to Comparative Example 5 and 6 from Table 2, when nonvolatile hydrocarbon is used instead of the volatile hydrocarbon of the component (B), the skin and the hair become sticky and the cosmetic conforms to the skin. I also understand that it is bad. In addition, when the content of the component (B) is less than the range of the present invention, it is found that the skin and the hair become sticky, the cosmetic does not conform well to the skin, and the gloss and the fingerness of the hair are bad. When the content of the component (B) is higher than the range of the present invention, it is found that the skin and the hair are not sticky, but the skin and the hair are moist and the gloss and the cohesion of the hair are inferior.

  From Table 3, among the (C) components, myristyl alcohol is the other (C) component in terms of skin and hair stickiness and moisturization, cosmetic compatibility with the skin, hair softness, gloss and fingerability. It turns out that it is superior. When the content of the component (C) is less than the range of the present invention, it can be found that the skin and the hair can not be moistened, and the softness and the fingerness of the hair are bad. When the content of the component (C) is more than the range of the present invention, it is understood that the skin and the hair become sticky and the skin is not familiar.

It can be seen from Table 4 that blending the component (D) can impart moisture to the skin and hair without causing stickiness to the skin and hair, and also improves the skin familiarity of the cosmetic.
From Table 5, it can be seen that when the component (E) is blended, the fingering of the hair becomes good. Tri (caprylic acid / capric acid) glyceryl is blended in the commercially available product RUSPLAN SR-DM4 used for blending the component (E). It can be seen that acid / capric acid) glyceryl is not effective in improving the fingering of the hair.

It can be seen from Table 6 that blending of the component (F) improves hair cohesion.
From Table 7, it can be seen that the gloss of the hair is improved when the (G) component is blended.
From Table 8, it can be seen that the cosmetic containing the components (A) to (G) in the amount specified in the present invention is excellent in the ultraviolet light protective effect and excellent in the effect of improving the skin condition and the hair condition.
