AvoidNo. Animal product not typically used in food (more typically seen in medications, supplements, cosmetics and/or cleaning supplies).
Sodium Undecylenate and the Vegan Diet
Sodium undecylenate is the sodium salt of undecylenic acid, which is a fatty acid derived from castor oil. It is primarily used in the formulation of antifungal products and personal care items, such as shampoos and creams, due to its antimicrobial properties. While it is not typically found in food products, it is considered safe for incidental contact, such as in topical applications. Sodium undecylenate is not derived from animal sources, making it suitable for vegan use in non-food applications.
