What is Propylene Glycol?
E1520 is the E-number for propylene glycol, one of the humectants group of food additives (E400–E1520). Additives in this group keep foods moist and stop them drying out. Produced synthetically from petroleum. Like every E-number, E1520 has been evaluated and authorised for use in food in the European Union — the 'E' literally stands for Europe, and a number is only granted after a safety assessment. That authorisation doesn't mean every additive suits every diet or that all concerns are settled, which is why we break down the safety, vegan, vegetarian and halal status of E1520 in detail below.
