Also known as
2-Ethylhexyl 2-cyano-3,3-diphenylacrylate Eusolex OCR Parsol 340 2-Ethylhexyl cyanodiphenylcrylate
Compatibility
Works well with:
Avobenzone Homosalate Octisalate Titanium Dioxide Zinc Oxide Butyl Methoxydibenzoylmethane
Use caution with:
Bemotrizinol
Octocrylene is well known as a photostabilizer for Avobenzone, preventing its photodegradation and extending broad-spectrum protection over time. It is oil-soluble and should be incorporated into the oil phase of emulsions. Some studies suggest potential incompatibility with Bemotrizinol due to crystallization concerns, and it may react with retinol or retinyl palmitate on storage, forming adducts that reduce retinoid efficacy.
Formulation notes
Octocrylene is an oil-soluble UVB and short UVA chemical sunscreen filter that absorbs UV radiation primarily in the 280–320 nm range, with some coverage up to ~360 nm. Formulators value it for its dual role as both a UV filter and a photostabilizer for the notoriously unstable Avobenzone. It has been flagged for potential endocrine activity and accumulation in aquatic organisms, so some formulators are moving toward alternatives; regulatory limits are set at 10% in the EU and 10% in the US (OTC monograph).
