Description
Triacetin (CAS 102-76-1), also known as triacetine, E1518, and FEMA 2007, is the triester of glycerol and acetic acid. It is approved as a food additive under E-number E1518 and is commercially available from multiple European chemical distributors under these designations.
In food and flavour applications, triacetin functions as a solvent and carrier for flavour compounds, improving their dispersion and stability in finished products. In personal care formulations, it acts as a plasticiser and fixative in fragrance systems, slowing the evaporation rate of volatile aroma components to extend scent longevity.
Triacetin is supplied in food-grade and cosmetic-grade liquid form, meeting FCC, Ph.Eur., and REACH compliance requirements. It is classified under HS code 29153930 for EU trade purposes. Standard packaging includes drums and IBC containers, with documentation available to support regulatory submissions across food and personal care categories.
