Quillaja saponaria extract

Quillaja saponaria extract (CAS 68990-67-0), also supplied under trade designations such as Quillajanin C 100 and QL 1000, is a plant-derived saponin concentrate obtained from the bark of the soapbark tree. It functions as a natural emulsifier, foaming agent, and flavoring ingredient across food, personal care, and agricultural applications. In food and beverage manufacturing, it stabilizes emulsions and generates foam.

This extract is used in products such as soft drinks, beer, and confectionery coatings where a clean-label surfactant is required. Personal care formulators use it to build foam and improve sensory texture. It is commonly found in shampoos, facial cleansers, and natural cosmetic formulations. In agriculture, it acts as an adjuvant in spray formulations, improving the spreading and adhesion of active ingredients.

Its FEMA 2973 status also qualifies it as a flavoring agent in specific food applications where its characteristic profile is commercially relevant. The extract is available as a liquid concentrate and powder. Saponin content varies by grade to suit different application requirements. Food-grade and technical-grade specifications are standard across the market, with food-grade material conforming to FCC requirements.

Buyers should confirm saponin purity levels and solvent residue specifications when evaluating suppliers. This is particularly important for regulated food or pharmaceutical end uses to ensure compliance.
