What is quillaja extract made of
Quillaja saponaria extract (also spelled “quillaia”) is a dark brown liquid made from the logs and bark of the soapbark tree. It has a sweet, pungent odor.[1] The word quillay is derived from the native Mapuche word quillean, which means “to wash.”[2] The soapbark tree is a large evergreen with shiny, leathery leaves and a thick bark. It is native to Chile. The wood for the extract is often obtained through regular pruning activities that improve forests without killing the trees.
