UV Filter

Octocrylene

Octocrylene is an oil-soluble organic chemical UV filter (INCI: Octocrylene) that absorbs UVB and short-wave UVA II radiation, with peak absorption at 304 nm. It works by converting UV energy into heat, preventing it from penetrating the skin. Beyond direct UV protection, it is valued in formulations for its ability to photostabilise other UV filters — particularly avobenzone — and for improving the water resistance of sunscreen products.
