Is Glycerol Safe?
Glycerol is the additive E422 — a sweet-tasting liquid that keeps food moist — usually plant-derived, but can come from animal fat.
Is Glycerol safe to eat?
E422 is considered safe. It is authorised across the EU, UK and US, and safety evaluations by the European Food Safety Authority (EFSA) have not identified health concerns at the levels used in food. For most people there is no reason to avoid E422.
EFSA status: Authorised in the EU — no safety concern at current levels of use

What is Glycerol?
E422 is the E-number for glycerol, one of the humectants group of food additives (E400–E1520). Additives in this group keep foods moist and stop them drying out. Made from plant oils (including palm), synthetically, or from animal fats. Glycerol can be made from plant oils (commonly palm or coconut), synthesised from petroleum, or derived from animal fats — so vegans and halal consumers need to check the source with the manufacturer. Like every E-number, E422 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 E422 in detail below.

Frequently Asked Questions
Is Glycerol bad for you?
Yes. E422 is authorised in the EU, UK and US, and EFSA evaluations found no health concern at normal food levels.
Is Glycerol vegan?
E422 is uncertain for vegans — it is made from plant oils (including palm), synthetically, or from animal fats, and the label doesn't reveal the source. Look for a vegan certification or ask the manufacturer.
Is Glycerol halal?
E422 is mashbooh (doubtful) — made from plant oils (including palm), synthetically, or from animal fats. Verify the source with the manufacturer or choose halal-certified products.
