[ Introduction ]
Quillaja saponin is a natural triterpenoid glycoside extract derived from the bark of the Quillaja saponaria (soapbark) tree. It acts as a potent, non-ionic surfactant with strong foaming, emulsifying, and membranolytic properties, widely used in food, pharmaceutical, cosmetic, and veterinary applications. It also serves as an adjuvant, detergent, preservative, emulsifier, and foam-forming agent.

[ Uses ]
- Serves as a natural emulsifier and foaming agent in beverages, personal care products, and topical formulations.
- Functions in pharmaceutical and biotechnological fields as an adjuvant and detergent—enhancing membrane permeability and aiding in vaccine or drug delivery.
- Employed in aquaculture and agriculture as a bio-active agent—demonstrating antiparasitic activity against sea lice and protective effects against bacterial infections and oxidative damage in animal models.
