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 “E491” or “Sorbitan Monostearate”, no qualifier | Uncertain — source unstated. A strict vegan may want to avoid or contact the manufacturer. |
| “Of vegetable origin” or “vegetable sorbitan monostearate” | Vegan-safe — plant-derived, confirmed by the wording itself. |
