Ziziphus Joazeiro Bark Extract

Ziziphus joazeiro bark extract is a botanical extract derived from the bark of the Juazeiro tree (Ziziphus joazeiro), and can be used in hair care to help control dandruff.

Ziziphus joazeiro is a shrubby tree in the buckthorn (Rhamnaceae) family, native to Brazil and other parts of South America. Trees grow up to 15 meters tall, with waxy leaves, yellow flowers and small round edible fruit. The inner bark of the tree is naturally rich in saponins (plant compounds which produce foam), and has a history of use in infusions such as shampoos, tonics and traditional medicines.

Ziziphus Joazeiro bark extract contains the antibacterial compounds betulinic, ursolic and alphitolic acids; and has been shown to have mild antibacterial and antifungal properties. It can be used in hair care to help control dandruff and soothe the scalp.
