Bovine Bile Extract

Bovine Bile Extract is a complex biological mixture obtained from the gallbladder or bile ducts of cattle, containing bile salts (primarily sodium taurocholate and sodium glycocholate), cholesterol, phospholipids, and bile pigments. Its naturally occurring bile salts act as highly effective biological emulsifiers and surfactants, capable of solubilizing fats and lipids in a manner that closely mimics the body's own digestive and skin-barrier chemistry. Formulators working with specialized skincare, barrier-repair, or veterinary cosmetic products may select this ingredient for its biocompatibility and its unique ability to enhance the penetration and dispersion of lipophilic actives, though its animal origin limits its use in vegan or cruelty-free formulations.
