Is Stearyl Tartrate vegan?
Stearyl Tartrate
Stearyl Tartrate is an emulsifier produced by esterifying stearyl alcohol with tartaric acid. Stearyl alcohol may be derived from animal or vegetable sources, while tartaric acid is typically plant-derived (from grapes). It is used in bakery products and food as a dough conditioner.
Why unconfirmed?
Stearyl Tartrate 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.
