防晒成份，油性化学性紫外线吸收剂，危险指数为 2/5(越高越不好)[1]。 防晒
Octocrylene是较为新型的防晒成分，属于油溶性化学防晒剂，可吸收紫外线中波段在250～360的UVA和UVB，在防晒霜中经常搭配其他防晒剂一起使用，能达到较高的SPF防晒指数，不过Octocrylene暴露在阳光下会释放出氧自由基。
长期可能导致老化，须考虑使用
"Perhaps the best approach to stabilizing avobenzone is to incorporate octocrylene (EU) in the formulation to help prevent the formation of the triplet state. Octocrylene is also a globally approved sunscreen (although some evidence suggests octocrylene may itself be a photo-sensitizer, causing indirect DNA damage). The key L’Oreal patents (in the United States) for stabilization of avobenzone using octocrylene expired in late 2014 and are now freely available."
