The exact wording on the pack is the best clue you have when the source isn't stated outright:
| What the label says | What it means |
|---|---|
| Just “E435” or “Polyoxyethylene Sorbitan Monostearate”, no qualifier | Uncertain — source unstated. A strict vegan may want to avoid or contact the manufacturer. |
| “Of vegetable origin” or “vegetable polyoxyethylene sorbitan monostearate” | Vegan-safe — plant-derived, confirmed by the wording itself. |
| Certified vegan logo on the pack | Confirmed — the manufacturer has already verified the source for you. |
| Marked Kosher Pareve | Helpful hint, not proof — pareve means no meat or dairy, which usually points away from an animal source, but isn't a vegan guarantee on its own. |
