摘要： PURPOSE:To evaluate ultraviolet ray transmission preventive effect of a specimen such as an anti-suntan cream without use of any vital organism by applying the specimen to the surface of an animal skin exfoliated film having ultraviolet transmissivity, irradiating it with an artificial light beam from one side, and measuring the dosage of ultraviolet rays transmitted. CONSTITUTION:A specimen 2 is applied to the surface of a hairless molmot skin 1, which is adhere4 to a rectangular holder 3 having a square aperture, and the holder 3 is held vertically by a stand. The irradiation part 41 of a solar simulator 40 is attached to the specimen side of the skin 1 while the light-receiving part 51 of an ultraviolet ray intensity meter 50 is attached to the other side, and the intensity E of the ultraviolet ray penetrating the specimen 2 and skin 1 is measured. Alike the intensity E0 of the ultraviolet rays is measured by using the skin 1 which is free from application of specimen 2, and E/E0 is used as the ultraviolet ray transmission prevention value. Accordingly the ultraviolet ray transmission preventive effect can quickly be evaluated without use of any vital organism.

摘要： PURPOSE:To provide a cosmetic excellent in ultraviolet irradiation-cutting effect, free from any problems such as safety, inhomogeneously whitish appearance and greasiness. CONSTITUTION:The objective cosmetic >=10 in sun protection factor can be obtained by formulating (A) 0.1-10wt.%, based on the final cosmetic, of an ultraviolet scattering agent in the form of fine particle aggregates 50-500mum in granular diameter in (B) a cosmetic base; or by formulating (C) 1-5wt.%, based on the final cosmetic, of an ultraviolet scattering agent containing >=20wt.% of fine particle aggregates 50-500mum in granular diameter.
