Is Sodium Stearoyl Lactylate vegan?
Sodium Stearoyl Lactylate
Sodium Stearoyl Lactylate is an emulsifier produced by reacting lactic acid with stearic acid and neutralizing with sodium hydroxide or calcium hydroxide. The stearic acid may be derived from animal (tallow) or vegetable sources, making the overall origin dual.
Why unconfirmed?
Sodium Stearoyl Lactylate 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.
