Last checked 15 Oct 2026 How we decide

Triacetin depends on the glycerol it is made from. E1518 is glycerol esterified with acetic acid, and that glycerol comes from vegetable oil, animal fat or chemical synthesis from propene. The label does not say which, so ask the supplier or look for a vegan mark.
