- UV blocking test was performed. To check UV protection, 28.6 mg of sunscreen was applied to HelioScreen Labs' HELIOPLATE HD6 (size: 4.7cm X 4.7cm), and the UV blocking ability 30 minutes later was measured using Labsphere Inc.'s UV-2000S device, a sunscreen analyzer. Confirmed. The test results were confirmed as shown in FIG. 5 .
- the UV protection factor was expressed as SPF.
- the inorganic composite pigment may be 0.1 wt% to 20 wt%, preferably 0.5 wt% to 10 wt%, based on the total weight of the sunscreen.
- the content of the inorganic composite pigment is less than 0.1% by weight, the UV blocking effect is remarkably reduced, and the effect of improving the feeling of use and forming hiding power is insignificant, and the UV blocking synergistic effect cannot be expected.
- the oily feeling is insufficient, and the mat is made, and it can give a heavy and stiff feeling of use.
