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