摘要:
Artificial skin having a thickness of 100 to 1,000 μm, and prepared from a polymer which, when formed into a thin film having a thickness of 100–1,000 μm, exhibits a percent transmission of light having a wavelength of 450–280 nm of at least 10%. In the artificial skin of the present invention, grooves which imitate furrows are provided on one surface. Also disclosed is a method for evaluating UV screening agents making use of the artificial skin of the present invention, on the basis of the relation between UV shielding power of a UV screening agent and UV transmission through the artificial skin.
