Estragole

Estragole (CAS 140-67-0), also known as esdragol, esdragon, 4-allylanisole, and FEMA 2411, is a naturally occurring phenylpropanoid found in tarragon, basil, and anise oils. It carries no assigned E-code and is classified under HS code 29093090.

In food and beverage formulation, estragole functions as a flavoring agent, delivering characteristic aniseed and tarragon notes at low use concentrations, typically in the low ppm range. In personal care applications, it acts as a fragrance component and antioxidant, helping to stabilize formulations against oxidative degradation through radical-scavenging activity.

Estragole is supplied as a liquid in standard commercial and flavor-grade specifications, with documentation available to support REACH compliance and FCC-aligned quality requirements. Procurement teams should note that the substance is subject to ongoing regulatory scrutiny under EU flavor legislation, and current restriction guidance should be confirmed prior to formulation.
