Novel sunscreen reagents from hydroxy-substituted acylglycerides

摘要: A class of UVA- and UVB-absorbing esters has been derived by modifying hydroxy triglycerides other acyltriglycerides with any a variety cinnamic acids. The esterification reactions are preferably conducted at elevated temperatures without catalyst. resultant agents have the advantage being synthesized from natural materials, while providing value-added use for oil. They readily formulated into standard UV-absorbing daily-wear cosmetic, hair skin care, sunscreen formulations.
