Octocrylene
What is Octocrylene?
Octocrylene is a synthetic organic compound chemically known as 2-ethylhexyl 2-cyano-3,3-diphenylacrylate. It belongs to the cinnamate family of chemical sunscreens and primarily functions by absorbing ultraviolet B (UVB) radiation in the 290-320 nm range. Upon absorption, it converts the energy into harmless heat, preventing UV penetration into the skin. Commonly used in daily moisturizers, lotions, and broad-spectrum sunscreens at concentrations up to 10%, it also stabilizes other UV filters like avobenzone against photodegradation. This enhances overall product stability and photoprotection efficacy. As a lipophilic ingredient, it integrates well into oil-based formulations, providing water-resistant properties ideal for recreational use. Regulatory bodies such as the FDA classify it as generally recognized as safe and effective in over-the-counter sunscreens.
