About

Nonenol (CAS 35854-86-5) is a nonenyl alcohol, an unsaturated nine-carbon fatty alcohol with a double bond in its chain. It functions as a fragrance ingredient and skin conditioning agent in cosmetics. The unsaturated C9 chain has mild sensitization potential at high concentrations, but at typical fragrance use levels it is considered safe. IFRA guidelines provide appropriate restrictions.
