METHOD FOR SUNLIGHT TEST OF COSMETIC PRODUCTS

摘要

PURPOSE: A sunlight test method of a cosmetic product is provided to replace real sunlight with Xenon light, and to shorten test time. CONSTITUTION: A sunlight test method of a cosmetic product comprises: a step of irradiating a cosmetic material by Xenon light; and a step of measuring image change of the cosmetic material by Xenon light. The intensity of Xenon light is 0.1W/m^2 to 1.45W/m^2 at a wavelength of 420 nm. The Xenon light is irradiated by a repeat mode of photoperiod and dark period or a constant mode of photoperiod. [Reference numerals] (AA) Intensity(W/m^2); (BB) Wavelength(nm)
