Glycerin (E422) can be plant-derived (halal) or animal-derived including pork (haram). Without "vegetable glycerin" labelling, the source is uncertain.
Also known as: Glycerol, E422, Vegetable glycerin, Glycerine
Where glycerin typically comes from
- Soybean, palm, or rapeseed oil (vegetable glycerin — halal)
- Animal fats from beef tallow or pork lard (haram unless source verified)
- Synthetic from petrochemicals (halal but uncommon in food)
Where you'll see it on a label
- Cake mixes, frostings, and packaged sweets
- Protein bars, energy bars, and granola bars
- Toothpaste, mouthwash, and personal care products
- Liquid medications, syrups, and gel capsules

Scholarly view
Vegetable glycerin is unanimously halal. Animal-derived glycerin from non-halal slaughtered animals is haram. Synthetic petroleum-derived glycerin is halal but rare in food applications.
Bottom line
Look for "vegetable glycerin" or a halal certification mark. Otherwise, treat as suspect.
