2-Ethylhexyl 4-methoxycinnamate

2-Ethylhexyl 4-methoxycinnamate (2-EHMC) is an ultraviolet B (UVB) blocker. Topical application of 2-EHMC prevents UV-induced edema and formation of cyclobutane pyrimidine dimers, a marker of DNA damage, in mouse skin. 2-EHMC is estrogenic, increasing uterine weight in female rats (ED50 = 934 mg/kg per day). It also induces bleaching of A. pulchra coral. Formulations containing 2-EHMC have been used as sunscreens.Formal Name: 3-(4-methoxyphenyl)-2-propenoic acid, 2-ethylhexyl ester.
