Beschreibung

Allgemeine Beschreibung

2-Ethylhexyl 2-cyano-3,3-diphenylacrylate is an ester-based UV filter formed by reacting 3,3-diphenylcyanoacrylate and 2-ethylhexanol. It is commercially used as a UV absorber in sunscreens and other cosmetic formulations.

Anwendung

• Photochemical response of the scleractinian coral Stylophora pistillata to some sunscreen ingredients: This study investigates the impact of octocrylene on the photosynthetic efficiency of coral symbionts, raising concerns about environmental effects (JP Fel et al., 2019).
• Preparation of O/I1-type emulsions and S/I1-type dispersions encapsulating UV-absorbing agents: Explores formulations for incorporating octocrylene into cosmetic products, enhancing UV protection capabilities (K Aramaki et al., 2015).
