[Unevenness correction effect]
The effect of making the unevenness of the skin inconspicuous while being transparent was evaluated by measuring the intensity of light diffusion over time. That is, if the effect of scattering light is high, it can be evaluated that the effect of correcting the 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 over time is measured after the application of the transparent solid cosmetic of the present invention, the intensity of light diffusion (relative value with immediately after value = 1) increases with time.

Moreover, an unblended graph (comparative example) is a composition in which only (a), (c) and (d) are replaced with (c) instead of not blending (b).
As can be seen from this graph, the transparent solid composition of the present invention exhibits an excellent unevenness correction effect in the specific composition of the present invention due to the component (b).

粉末の分散系では、外相と粉末の屈折率がある程度一致したところで透明性が向上する。よって、外相よりもかなり高い屈折率をもつ粉末（比較例２、３）を分散させた場合には透明性に劣る。また、外相と近い屈折率を有する粉末でも揮発性油分の配合量が少なければ、使用性に劣る（比較例１）。実施例１−４はこれらを満足するものである。 (1) Advantage (effect) of powder All components in Table 1 were weighed at room temperature and dispersed until uniform.

In the powder dispersion system, the transparency is improved when the refractive index of the external phase and the powder agree to some extent. Therefore, when powder (Comparative Examples 2 and 3) having a refractive index much higher than that of the outer phase is dispersed, the transparency is poor. Further, even a powder having a refractive index close to that of the outer phase is inferior in usability if the blending amount of the volatile oil is small (Comparative Example 1). Example 1-4 satisfies these requirements.

揮発性油分の配合量が増加すれば残存油分量が減り、油残り感が減るとともに、さっぱり感、さらさら感に優れる。 (2) Effect of Volatile Oil All components in Table 2 were weighed at room temperature, heated to 95 ° C., dispersed until uniform, degassed and solidified at room temperature.

If the amount of volatile oil increases, the amount of residual oil decreases, the feeling of oil residue decreases, and the refreshing and smooth feeling is excellent.

粉末の使用感触は配合量により異なる。今回の基剤において、球状粉末のさらさら感を出すには１５％以上の配合が必要であることがわかった。 (3) About the amount of powder All components in Table 3 were weighed at room temperature, heated to 95 ° C., dispersed until uniform, deaerated and solidified at room temperature.

The feeling of use of the powder varies depending on the amount. In this base, it was found that the blending of 15% or more is necessary in order to give a smooth feeling of the spherical powder.

高級アルコール、高級脂肪酸、ＰＯＥ・ＰＯＰジメチルエーテルの配合により、油浮きをはじめとする基剤の安定性の改善に成功した。 (4) Higher alcohol / higher fatty acid / POE · POP dimethyl ether All components in Table 4 were weighed at room temperature, heated to 95 ° C., dispersed until uniform, degassed and solidified at room temperature.

By blending higher alcohols, higher fatty acids, and POE / POP dimethyl ether, we succeeded in improving the stability of bases such as oil floaters.

上記実施例の透明化粧料は基剤外観の透明感に優れ（上記の透明性試験による評価はすべて５である）、使用感がよく、しかも毛穴の目立ちにくくする透明化粧料である。 The following transparent solid cosmetics were produced by a conventional method.

The transparent cosmetics of the above Examples are transparent cosmetics that are excellent in transparency of the base appearance (all the evaluations by the above-mentioned transparency test are 5), have a good feeling of use, and make pores less noticeable.

  The transparent solid composition of the present invention is excellent in transparency and is preferably used as a base for transparent solid cosmetics. And while exhibiting the outstanding transparency, the transparent solid cosmetic which makes the pores and fine lines of a face hard to be conspicuous by the uneven | corrugated correction effect of skin while being excellent in transparency can be provided. In addition, its stability and feel of use are extremely excellent.

It is a graph showing the intensity | strength of light diffusion.
