- Plain-language explanation
- E1520, or propylene glycol, is a synthetic liquid used as a solvent and moisture-retainer in foods, medicines, and cosmetics. It is typically produced from petroleum, but can also be made from glycerol, which may be derived from animal or vegetable fats. The halal status depends on its source: if it is from petroleum or plant-based glycerol, it is considered halal, but if the glycerol is from an animal source, it must be from a halal-certified animal. Major halal certification bodies generally accept E1520 as halal when its source is verified and properly documented.
