Octinoxate, also known as Ethylhexyl Methoxycinnamate is a commonly used chemical sunscreen that primarily absorbs UVB radiation but not UVA. It’s not very stable and should be combined with other sunscreens for broader protection. Some concerns exist about its hormonal effects, especially for pregnant individuals and young children. While there are newer and better options available today, it’s generally considered safe when used within regulatory limits.
