Is Sorbitan Stearate vegan?
Sorbitan Stearate
Sorbitan Stearate (Sorbitan Monostearate) is an emulsifier produced by reacting stearic acid with sorbitol, yielding a mixture of esters. Stearic acid can be derived from animal or vegetable fats, making the overall origin dual. It is commercially known as Span 60.
Why unconfirmed?
Sorbitan Stearate 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.
