Farnesol

Farnesol (CAS 4602-84-0, EC 225-004-1, C15H26O) is a naturally occurring sesquiterpene alcohol found in many essential oils and floral extracts. It is also referenced under the trade designations CSU 1806, FCI 119a, and Nikkosome, and carries the FEMA number 2478. No E-code designation applies to this substance.

In personal care formulations, farnesol functions as a fragrance fixative and hair conditioning agent, binding to the hair cuticle to improve texture and manageability. In coatings and adhesive systems, it acts as a reactive crosslinker, forming covalent bonds within polymer networks to improve film integrity and adhesion strength. It is also approved as a flavoring agent under FEMA 2478 for food-adjacent applications.

Farnesol is supplied as a liquid under HS code 29052200 and is subject to REACH registration requirements within the EU. Buyers should confirm supplier compliance with IFRA guidelines when sourcing for fragrance applications. Standard packaging formats and available purity grades should be confirmed directly with the supplier.
