Interpretive Summary:

Technical Abstract: Vitamins C and E and their derivatives are used as antioxidants in topical formulation in cosmetics and personal care products. Vitamin E (100 microM) was rendered a poor antioxidant in the 2,2-diphenyl-1-picrylhydrazyl (DDPH*, 200 microM) assays in acetonitrile, scavenging < 50 % of DPPH* within 30 min, after exposure to (UV) for 4 h. Vitamin C solutions (100 microM) were rendered moderate antioxidants, scavenging > 50 % of DPPH* within 30 min, after exposure to UV radiation for 4 h. Feruloyl soy glycerides (FSG) are UV absorbers synthesized from the biocatalytic conversion of soybean oil and ferulic acid ethyl ester that have a total UV absorbance and photostability comparable to the commercial UV absorber, octinoxate (ONX). FSG (100 – 1000 microM) was added to acetonitrile solutions of the vitamins and their derivatives to determine if FSG could photoprotect the vitamins and their derivatives, allowing them to retain their antioxidant efficacy after 4 h of UV irradiation. The addition of FSG, 500 and 1000 microM, allowed Vitamin E and most of the antioxidant derivatives to retain rapid antioxidant activity after 4 h UV exposure. Vitamin C retained rapid antioxidant capacity with 100 microM FSG after 4 h of UV exposure. FSG performed slightly better than the commercial UV absorber, ONX, in protecting the vitamins’ and their derivatives’ antioxidant activities from UV degradation. FSG also possessed intrinsic antioxidant capacity that ONX did not, which may have contributed to its better performance when mixed with the vitamin’s and their derivatives in the DPPH* assays.
