Octinoxate

Category: topical

Aliases: Octyl methoxycinnamate, OMC, Parsol MCX

Pharmacological Mechanism

Cinnamate UVB absorber (280–320 nm). Combined with avobenzone for broad-spectrum coverage, though it can destabilise avobenzone → modern formulations add photo-stabilisers (octocrylene, Mexoryl). Environmental concerns drove Hawaii + Key West bans (coral bleaching).
