Alpha-Ionol

Alpha-Ionol (CAS 25312-34-9, EC 246-815-7, formula C13H22O) is a naturally occurring terpenoid alcohol also known by the trade name Latilure and the identifier Ai3-36071. It carries no assigned E-code. The compound belongs to the ionone family and is recognised as a fragrance and flavoring ingredient in both European and international regulatory frameworks.

In personal care formulations, Alpha-Ionol contributes violet-woody and floral facets to fine fragrance and cosmetic products, functioning as an odor-active molecule that binds to olfactory receptors at low use concentrations. In food and beverage applications, it acts as a flavoring agent where its characteristic berry and rose-like profile modifies the sensory character of the finished product.

Alpha-Ionol is supplied as a liquid oil and is subject to REACH registration requirements for EU market access. Procurement teams should confirm supplier compliance with IFRA guidelines for fragrance applications and FCC specifications where food-grade material is required.
