The short answer
Glycerin (glycerol, E422) can be made from plant oils, animal fat, or petroleum. Plant-based and synthetic glycerin are halal; animal-derived is only halal if from a permissible, halal-slaughtered source (and pork-derived is haram). Labels rarely say which, so plain "glycerin" is best treated as doubtful unless it's vegetable, vegan, or halal-certified.
The short version
Glycerin is a sweet, syrupy substance used in food, drinks, and personal-care products. It comes from one of three places: plant oils, animal fat, or petroleum.
By source
- Plant-based (palm, soy, coconut) — halal.
- Synthetic (from petroleum) — halal; no animal material.
- Animal-based — only halal if from a halal-slaughtered permissible animal; pork-derived is haram.
What to check yourself
- "Vegetable glycerin", a vegan mark, or a halal logo → halal.
- Plain "glycerin"/"glycerol"/E422 with no source → treat as doubtful; confirm with the maker.
