Is Polysorbate 20 vegan?
Polysorbate 20
Polysorbate 20 (E432) is a nonionic surfactant and emulsifier produced by ethoxylation of sorbitan monolaurate. The sorbitan is derived from plant-based sorbitol, while the lauric acid component may come from coconut or palm oil (plant-derived) or animal fats. It is widely used in food, cosmetics, and pharmaceuticals.
Why unconfirmed?
Polysorbate 20 can be either derived from animal, or non-animal sources. The ingredient name itself is identical either way, so the label alone can’t tell you which. Only a supplier declaration can.
