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]。
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."
