Science
Mechanism of Action
Opoponax oil's biological activity is attributed to its complex chemical composition, which includes phenolics, diterpenes, coumarins, and phthalides. These compounds are believed to confer antioxidant and antimicrobial actions. In topical applications, the oil is traditionally associated with antiseptic and anti-inflammatory effects, contributing to the management of minor skin irritations and possessing astringent qualities that may promote skin rejuvenation.

Formulation
Stability
Opoponax oil exhibits good stability under standard storage conditions. For optimal shelf life, it should be kept in an airtight container at ambient temperature, in dry conditions, and away from light. Extreme heat should be avoided.
Safety
Safety Profile
Opoponax oil is phototoxic and presents a moderate risk of skin sensitization, potentially leading to irritation or allergic reactions. Its topical application is strongly discouraged for individuals with hypersensitive, diseased, or damaged skin. The SCCP acknowledged its allergenic potential but considered the risk low at a maximum concentration of 0.6% in finished cosmetic products. It holds FDA GRAS status for food flavoring, which does not extend to specific cosmetic approval.
