Is Potassium Lactate vegan?
Potassium Lactate
Potassium lactate is the potassium salt of lactic acid, used as a humectant, preservative, and acidity regulator. Lactic acid can be derived from fermentation of plant-based carbohydrates or from animal sources, so the origin of potassium lactate depends on the production method.
Why unconfirmed?
Potassium Lactate 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.
