How Quillaja Saponaria (soapbark) extract Is Made

Quillaja saponaria extract is produced by aqueous extraction of the milled inner bark or wood of stems and branches of the soapbark tree. After harvesting the logs and bark, the external part of the bark is removed. The inner bark is then treated with hot water to obtain the extract.[8] 

One type of quillaja saponaria extract is treated with stabilizing agents and then filtered. The liquid is then concentrated via evaporation and sold; it can also be spray-dried and sold as a powder. A second type of quillaja saponaria extract is put through extra filtration, typically via activated charcoal, to remove unwanted solids.[9]
