Vegan
Depends on the source
Halal
Mushbooh (doubtful)
The honest version
Can be made from vegetable oils or from animal fat. Food-grade glycerol is usually plant-based today, but the label does not say, which is why certifiers ask the manufacturer.
When our checker meets E422 on a label, it does not guess: products carrying ambiguous additives get a “check the label” verdict, with the ingredient named, so you can decide or ask the manufacturer.
