| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an external preparation for skin which can protect the skin from near infrared rays effectively.SOLUTION: The invention provides an excellent external preparation for skin which can provide not only a scattering effect of near infrared rays but also a natural finish with a bare skin feeling by containing 1) titanium dioxide having an average particle diameter of 0.5-2.0 μm, 2) an inorganic plate-shaped powder having a gross value of 9.0 or less measured under a light receiving condition where the refractive index is 1.60 or more and the incident/light receiving angle is 45°.
【課題】近赤外線から皮膚を効果的に保護することができる皮膚外用剤を提供することを課題とする。【解決手段】１）平均粒径が０．５〜２．０μｍである二酸化チタンと、２）屈折率が１．６０以上であり、４５?入射、４５?受光の条件で測定したグロス値が９．０以下である無機板状粉体を含有することにより、近赤外線の散乱効果のみならず、素肌感のある自然な仕上がりが可能な優れた皮膚外用剤となる。【選択図】なし |
