Abstract: Ultraviolet spectrophotometry for selecting and compounding of 16 kinds of natural UV absorbents was studied.Results showed that a blend composed of extract of equal mass of Chinese traditional herb medicines namely,Basil,Tsaoko,Coltsfoot flower,Alpinia,Linden tree flower,Sage and Sophora japonica displays good UV protection effect.Meanwhile,chemical UV absorbents were also studied to find an optimized UV absorbing formulation.Combination and amount of chemical UV absorbents were optimized as follows:ethylhexyl methoxycinnamate,7.0%;octocrylene,2.0%;diethylamine hydroxybenzoyl hexyl benzoate,3.0%.The application research was done,and results showed that when 5% of the UV absorbent blend made of Chinese traditional herb medicines is compounded with the optimized blend made of chemical UV absorbent combination,the SPF and PFA value of application product achieves 31.1 and 8.7 respectively,which meets the required effect of protection from broad-spectrum UV and the skin irritation of the product reduces significantly.
