Is Stearic Acid vegan?
Stearic Acid
Stearic Acid is a saturated C18 fatty acid occurring naturally in animal fats (such as beef tallow, lard) and in plant-derived fats (such as palm oil, shea butter, and cocoa butter). It is widely used in cosmetics and personal care products as an emulsifier, thickener, and skin-conditioning agent.
Why unconfirmed?
Stearic Acid 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.
