What It Does

Ethylhexyl Methoxycinnamate is a synthetic UV filter that provides broad-spectrum UVB protection with some UVA coverage, absorbing light primarily in the 280-320 nm range. This oil-soluble cinnamate derivative is one of the most widely used UV filters globally due to its excellent photostability, high extinction coefficient, and ability to dissolve easily in cosmetic oils and emollients. Formulators favor it for its light, non-greasy feel and its compatibility with other UV filters, making it a cornerstone ingredient in sunscreens and daily moisturizers with SPF protection.
