Octinoxate

Octinoxate, also known as ethylhexyl methoxycinnamate or octyl methoxycinnamate, is an organic compound and sun filter that absorbs UV-B rays from the sun. 

 

It's used in many products, including:
sunscreens, lip balms, moisturizers, makeup, perfumes, hair sprays, aftershaves, hair color products, shampoos, lipstick, nail polish, and skin creams.

Animal studies have reported octinoxate has hormone effects on the metabolic system and affects thyroid hormone production, with some evidence for other endocrine targets, including androgen and progesterone signaling. Octinoxate can also cause allergic reactions.
