Its natural foaming properties make it an effective emulsifier and surfactant, capable of removing dirt, oil, and impurities from the skin or surfaces.
Apart from its cleansing properties, soapbark also possesses other potential benefits. It has demonstrated anti-inflammatory, antimicrobial, and antioxidant properties, which may contribute to its applications in skincare. Additionally, soapbark has been utilized in traditional medicine for its expectorant and cough-suppressing properties.

The word "soapbark" is a compound word composed of "soap" and "bark".
The term "soap" comes from the Old English word "sāpe", which derived from the West Germanic word "saipo" and the Proto-Germanic word "*saipō". This then can be traced back to the Proto-Indo-European root "*seib(h)-" meaning "to pour out, to drip".
"Bark", on the other hand, comes from the Middle English word "barke", which evolved from the Old Norse word "bǫrkr" and the Proto-Germanic word "*barkuz". This can be traced further back to the Proto-Indo-European root "*bʰergʰ-" meaning "to shine, to gleam".
