About

Guaiyl acetate, a sesquiterpene acetate derived from guaiac wood oil, carrying GHS classifications for skin and eye irritation in cosmetic use.

Guaiyl acetate is classified H315 (skin irritation) and H319 (eye irritation) under GHS. It is not listed in EU cosmetic restriction Annexes but falls under IFRA guidelines for safe use. As a saturated bicyclic sesquiterpene acetate from natural guaiac wood origin, it presents lower environmental toxicity than many unsaturated terpenes. The octahydro-dimethylazulenyl ethyl acetate structure provides characteristic amber, woody and slightly floral notes in fragrance compositions.

Known concerns

  • H315 skin irritation hazard
  • H319 eye irritation hazard
  • IFRA usage guidelines apply
