experiment example 1
[0057] SPF measurement of an organic sunscreen for UV protection containing afudouside
[0058] SPF values were determined according to the following protocol. Specifically, the organic sunscreen for preventing ultraviolet rays prepared in the above-mentioned Example 1 and the organic sunscreen for preventing ultraviolet rays of the control group that did not contain afredouin were uniformly coated with the same amount by the same method. On a rough polymethylmethacrylate PMMA plate (Sa = 2 μm, 50x50 mm). After drying for 10 minutes, UV absorbance was measured at a plurality of positions on the PMMA plate using a measuring device (UV Transmittance Analyzer (UV Transmittance Analyzer) UV-2000S, Labsphere). The results are shown in Table 2 below.
