Description
Vanillin (CAS 121-33-5) is a phenolic aldehyde derived from vanilla beans or synthesized from guaiacol or lignin, commercially known under trade names including Lioxin and Zimco. It is registered under EC 204-465-2 with the FEMA designation 3107 and carries the molecular formula C8H8O3.
In food and beverage manufacturing, vanillin functions as a primary flavoring agent, mimicking natural vanilla character at controlled concentrations, and acts as an antioxidant by scavenging free radicals to extend shelf life. In personal care formulations, it serves as both a fragrance component and a UV absorber, helping to stabilize color-sensitive systems against photodegradation.
Vanillin is available in pharmaceutical-grade (Ph.Eur., USP/FCC) and food-grade forms as a crystalline powder, compliant with REACH regulations and suitable for use across EU markets. Standard packaging includes fiber drums and multi-layer bags; documentation including COA, MSDS, and origin declarations is available on request.
