FARNESAL.

Avoid CAS 19317-11-4 / PERFUMING

Farnesal is a naturally occurring aldehyde that acts as a precursor to Farnesol, a compound associated with potential antimicrobial, anti-inflammatory, and skin-regenerating properties. However, its direct benefits for skin, independent of its conversion, are not extensively detailed. Despite its use as a flavoring agent, aggregated GHS data indicates a significant risk of skin irritation and allergic sensitization.

Summary

Antimicrobial (via Farnesol) Anti-inflammatory (via Farnesol) Wound-healing agent (via Farnesol) Cell regenerator (via Farnesol)

Science

Mechanism of Action

Farnesal functions primarily as a precursor molecule, metabolizing into Farnesol within the skin. Farnesol is recognized for its ability to reduce microbial proliferation, mitigate inflammation, and support wound healing, often by activating the PPARα signaling pathway and promoting epidermal keratinocyte differentiation. The specific mechanisms by which Farnesal directly influences skin health, separate from its conversion to Farnesol, are not extensively documented.

Stability

Farnesal's activity or release can be influenced by pH, as evidenced by its use in pH-sensitive polymeric micelles designed for acidic release in dental applications. A general optimal pH range for its stability within cosmetic formulations is not specified.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Farnesal is an FDA-approved flavoring agent. However, aggregated GHS information reveals significant dermal safety concerns: 94.6% of reports indicate skin irritation (Skin Irrit. 2), and 91.9% suggest a potential for allergic skin reactions (Skin Sens. 1B). This implies a high potential for dermal irritation and sensitization, with no specified maximum safe concentration for cosmetic use.

Our Assessment

Verdict

Avoid

Due to a very high potential for skin irritation and allergic sensitization, coupled with a lack of direct clinical efficacy data for skincare, Farnesal is an ingredient that should be avoided in cosmetic formulations.
