Description

  The present invention includes a non-aqueous hair cosmetic that contains an ultraviolet absorber, has excellent low-temperature stability, and can improve the fingering of dried hair, and a hair treatment method using the non-aqueous hair cosmetic It is about.

  Conventionally, in order to avoid the adverse effects of ultraviolet rays, UV absorbers have been added to skin cosmetics such as sunscreen creams. Recently, however, it has become possible to prevent hair damage due to ultraviolet rays. Accordingly, hair cosmetics containing UV absorbers have been developed.

  As such a hair cosmetic, for example, an aerosol type spray type that is sprayed onto the hair to adhere various components including an ultraviolet absorber (Patent Document 1) has been proposed. With such a type of hair cosmetic, for example, an ultraviolet absorber can be effectively attached to the hair after styling without destroying the hairstyle.

JP, 2015-113281, A (Claims etc.)

  On the other hand, for example, there is a need to add a UV absorber to a leave-on type hair cosmetic that is used without being washed away so as to protect the hair from UV rays. However, when a hair cosmetic containing an ultraviolet absorber is applied to wet hair and dried by using a drier or the like, the hair tends to be bundled during drying and the fingering after drying becomes poor.

  In addition, hair cosmetics containing ultraviolet absorbers are likely to become cloudy when placed under a low temperature such as the winter air temperature in cold regions. Unlike aerosol sprays, leave-on hair cosmetics may be commercialized in transparent containers where the contents can be seen, but they are exposed to low temperatures during distribution and storage in warehouses. If it becomes cloudy, the commercial value may be reduced.

  The present invention has been made in view of the above circumstances, and an object thereof is a non-aqueous hair makeup that contains an ultraviolet absorber, has excellent low-temperature stability, and can improve the fingering of dried hair. And a hair treatment method using the non-aqueous hair cosmetic.

The non-aqueous hair cosmetic composition of the present invention that can achieve the above-mentioned object is formulated with the following components (A) to (C), and is applied to wet hair and then dried without washing off the hair. It is characterized by being used.

  As shown in Table 4, when the non-aqueous hair cosmetics of Examples 4a and 4b blended with the component (E) macadamia nut oil and meadow foam oil were used, the uniform softness of the hair was the standard. This was better than the case of using the non-aqueous hair cosmetic of Example 4e [non-aqueous hair cosmetic containing no component (E)].

  In contrast, the non-aqueous hair cosmetics of Examples 4c and 4d in which other vegetable oils are blended in place of the component (B), and components that impart softness to the hair without blending the component (B) are known. Example 4f in which the blending amount of the highly polymerized methylpolysiloxane and dimethiconol used was increased, and when 4 g of the non-aqueous hair cosmetic was used, the softness with a uniform feeling of hair was the standard of Example 4e. This was equivalent to the case of using a non-aqueous hair cosmetic.
