Octinoxate has been detected in human urine, blood and breast milk, which indicates that humans are systemically exposed to this compound. [1],[2] Octinoxate is an endocrine disruptor that mimics estrogen and can disrupt thyroid function.
WHAT IS OCTINOXATE?
Octinoxate filters UV‐B rays from the sun. 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. It is found in hair color products and shampoos, sunscreen, lipstick, nail polish, and skin creams. [5] In products other than sunscreens, it is used as a UV filter to protect the products from degrading when exposed to the sun.
