"A cinnamate is a compound chemically related to cinnamon oil and other cinnamon-related compounds that are used widely as flavourings and fragrances in many toiletries and cosmetics. Cinnamates are also potent UVB absorbers and therefore used in sunscreen agents and colour cosmetics with sun protection factor qualities." - DermNetnz.org
An "important function of cinnamic acid derivatives in cosmetics is UV protection. Ester derivatives such as ethylhexyl methoxycinnamate (octinoxate), isoamyl p-methoxycinnamte (amiloxiate), octocrylene and cinoxate are used in cosmetics all over the world as UV filters. However, their maximum concentrations in cosmetic products are restricted due to their adverse effects, which include contact and a photocontact allergies, phototoxic contact dermatitis, contact dermatitis, estrogenic modulation and generation of reactive oxygen species." - NCBI
