QUILLAJA SAPONARIA BARK

Quillaja Bark Extract

Safety grade: A

Quillaja bark extract comes from the bark of the quillaja tree, a plant native to South America. It contains natural compounds called saponins that create a natural, soap-like effect when mixed with water.

This ingredient is used in cleansers and shampoos to help remove dirt and oil from skin and hair, create a rich lather, and help blend oil and water-based ingredients together in the product.
