UV-absorbing sunscreen agent and fragrance fixative; may cause allergic reactions.

Hexyl salicylate is an EU-authorized UV filter (listed in EU Regulation 1223/2009 Annex VII) used for UVB protection in sunscreen and skincare products at maximum concentrations up to 5%. It also functions as a fragrance ingredient and fixative. It has a favorable safety profile comparable to other salicylate UV filters, though like all salicylates it carries salicylate allergy labeling requirements.

  • Fragrance fixative and skin conditioning

Known concerns

  • Salicylate allergy concern (cross-reactivity)
  • Must declare UV filter function if used above threshold
