[Roughness correction effect]

 The effect of making the skin irregularities inconspicuous while being transparent was evaluated by measuring the light diffusion intensity over time. In other words, if the effect of scattering light is high, it can be evaluated that the effect of correcting unevenness of the skin is high. This mechanism can be evaluated by measuring the light diffusion intensity of the transparent solid composition over time.

 When the intensity of light diffusion of the transparent solid cosmetic of the present invention is measured over time after application, the intensity of light diffusion (relative value with the immediate value = 1) increases with time.

 This graph is shown in Figure 1. In the graph of FIG. 1, the graph of the volatile oil content (the present invention) is the composition of Example 17 in which the essential components (a), (b), (c), (d) and (e) are all blended. The unblended graph (comparative example) is a composition in which only (a), (c), and (d) are used, and (b) is replaced with (c) instead of (b).

 As can be seen from this graph, the transparent solid composition of the present invention exhibits a more excellent unevenness correction effect than the specific composition of the present invention due to the component (b).

In a powder dispersion, transparency is improved when the refractive index of the external phase and that of the powder match to some extent. Therefore, when powder having a higher refractive index than the external phase (Comparative Examples 2 and 3) is dispersed, transparency is poor. In addition, even a powder having a refractive index close to that of the external phase is inferior in usability if the amount of the volatile oil component is small (Comparative Example 1). Example 14 satisfies these requirements. It is.

 (2) Effect of volatile oil

 At room temperature, all components in Table 2 were weighed, heated to 95 ° C, dispersed until uniform, degassed, and solidified at room temperature.

 [Table 2]

 Increasing the amount of the volatile oil reduces the amount of residual oil, reduces the feeling of oil residue, and provides excellent squashiness and smoothness.

 (3) Regarding the amount of powder

 At room temperature, all components in Table 3 were weighed, heated to 95 ° C, dispersed until uniform, degassed, and solidified at room temperature.

[Table 3]

 The feeling of use of the powder varies depending on the amount. With this base, it was clear that at least 15% of the blend was necessary to give a smooth feeling to the spherical powder.

 The transparent cosmetics of the above examples are excellent in transparency of the appearance of the base (all evaluated by the above-mentioned transparency test are 5), and are clear cosmetics that have a good feeling in use and make the pores stand out.

Industrial applicability The transparent solid composition of the present invention has excellent transparency and is preferably used as a base for transparent solid cosmetics. In addition, it is possible to provide a transparent solid shampoo that exhibits outstanding transparency and has excellent transparency, and has a skin unevenness-correcting effect that makes the pores and fine lines on the face stand out. Further, its stability and feeling of use are extremely excellent.
