FARNESENE.

Questionable CAS 502-61-4 (a-) / 18794-84-8 (b-) / FRAGRANCE, PERFUMING

Farnesene is a naturally occurring sesquiterpene recognized for its potential anti-inflammatory and antioxidant activities, primarily influencing neutrophil behavior. However, its application in precision skincare requires careful consideration due to its volatile nature and documented risk of skin sensitization.

Anti-inflammatory Antioxidant Fragrance

Science

Farnesene acts as a prospective anti-inflammatory agent by inhibiting human neutrophil activation and chemotaxis. Clinical studies at micromolar concentrations (1.2-2.6 µM) suggest its capacity to modulate immune responses. Additionally, it exhibits antioxidant properties, contributing to cellular protection.

While Farnesene possesses intriguing biological activities, its primary prevalent use in cosmetics is as a fragrance ingredient. The potential for allergic skin reactions and irritation at unspecified concentrations highlights a need for judicious formulation rather than casual inclusion for marketing claims without substantiation for skin benefits and safety profile in topical applications.

Stability

Farnesene is a volatile compound prone to oxidation upon air exposure, which can lead to the formation of potentially damaging byproducts. Formulations should prioritize protection from air to maintain stability and efficacy.


Safety

CIR Status
Not reviewed
Sensitization risk Moderate

Farnesene holds Generally Recognized as Safe (GRAS) status as a food additive by the US FDA. However, European regulatory bodies (ECHA, SCCS) have identified it as a potential skin irritant and a component in fragrance allergens within cosmetic products, suggesting a clear risk for topical application despite its food safety status.

Our Assessment

Questionable

Farnesene demonstrates promising anti-inflammatory and antioxidant properties, but its volatility, potential as a fragrance allergen, and risk of skin irritation necessitate a cautious approach to its inclusion in precision skincare formulations.
