Common Name

Octyl 4-methoxycinnamic acid

Description

Octyl 4-methoxycinnamic acid, also known as parsol or 2-ethylhexyl-4-methoxycinnamate, belongs to the class of organic compounds known as cinnamic acid esters. These are compound containing an ester derivative of cinnamic acid. Octyl 4-methoxycinnamic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). Its use in pharmaceutical and cosmetic formulations is approved by FDA. Acts as a photoprotective agent that protects the skin by preventing and minimizing the damaging effects of ultraviolet (UV) rays of natural light. It was originally developed in 1950's as an organic UV-B filter that absorbs UV-B rays from sun. Like any other photoprotective agents, octinoxate prevents the damage to cells and deoxyribonucleic acid (DNA) by reducing the p53 protein expression following UV exposure and also increases the skin's tolerability to UV rays . UV-induced molecular breakdown of octinoxate may interfere with cellular processes or induce oxidative damage in human skin . Can be enzymatically degraded by lipases in the stratum corneum where esters undergo hydrolysis . Octinoxate is a cinnamate ester and common ingredient in sunscreen and other skin care products to minimize DNA photodamage. Absorbs UV-B (predominantly) and UV-A rays while accumulating in the outermost layer of the epidermis.
