Octinoxate, also called Octyl methoxycinnamate or (OMC), is a UV filter. It can be absorbed rapidly through skin.Octinoxate filters UV‐B rays from the sun, although it does not protect against UV-A rays. Octinoxate dissolves in oil, which makes it a fat-seeking substance in the body. It is formed by combining methoxycinnamic acid and 2-ethylhexanol compounds which are not harmful on their own. When mixed together, they form a clear liquid that does not dissolve in water. Octinoxate is found in hair color products and shampoos, sunscreen, lipstick, nail polish, and skin creams. In products other than sunscreens, it is used as a UV filter to protect the products from degrading when exposed to the sun.
