INCI: Quillaja saponaria bark extract.
What is Quillaja Extrac?
Quillaja extract is obtained from the bark of the plant Quillaja saponaria. It is also commonly called soap bark/Panama bark/ Chinese bark tree. It is native to warm and temperate regions of Central Chile. It is a tree with dark, thick bark, fruits, and white-colored star-shaped flowers. The extract obtained from its bark consists of compound saponins. It has been traditionally used as a medicine to treat various chest problems in addition to its use in cosmetic products.
Use & Benefits:
Quillaja extract functions as a foaming agent, cleansing agent, emulsifying, surfactant, and skin conditioning agent. Saponins have foam-forming properties, which makes them useful as an excellent ingredient in body washes and cleansers. It is also used in shampoos to keep the scalp clean and reduce infections like dandruff. As a surfactant, it lowers the surface tension between two components of the product like two liquids or a liquid and a solid. When they are added they form a cluster, which has water-loving ions on end and fat-loving ions in the center. The fat-loving part attracts dirt, oil, and other impurities accumulated on the surface of the skin which then can be washed off easily with water with the help of a water-loving part. The same phenomenon is true for an emulsifier. It gives stability to the product by remaining as a common medium between oil and water-based components. As a skin-conditioner, it forms a protective film on the surface of the skin and makes it appears smooth and soft. It prevents loss of moisture from the skin and lubricates it. It conditions the skin and keeps it hydrated. It is used in formulations of creams, lotions, gels, shampoos, conditioners, and other personal care and skincare products.
