In the powder dispersion system, the transparency can be improved when the refractive index of the external phase and the powder are consistent to a certain extent. Therefore, the transparency at the time of dispersing a powder having a higher refractive index than that of the external phase (Comparative Examples 2, 3) was poor. In addition, if the compounding amount of the volatile oil component in the powder having a refractive index close to that of the external phase is small, the workability is deteriorated (Comparative Example 1). The results of Examples 1-4 meet these requirements.

(2) Effect of volatile oil

The total components in Table 2 were measured at room temperature and heated to 95° C., uniformly dispersed, and solidified at room temperature after degassing.

When the compounding amount of the volatile oil increases, the amount of residual oil decreases, and the feeling of oil residue decreases, and the refreshing feeling and dry feeling are excellent.

(3) Powder amount

The total components in Table 3 were measured at room temperature and heated to 95°C, uniformly dispersed, degassed and then cured at room temperature.

The feeling of use of the powder varies depending on the compounding amount. It was confirmed that in this base material, more than 15% must be added in order to express the dry feel of the spherical powder.

(4) Higher Alcohols/Higher Fatty Acids/POE·POP Dimethyl Ether

The total components in Table 4 were measured at room temperature, heated to 95° C., uniformly dispersed, degassed, and cured at room temperature.
