| This nut is known as soapberry or soapnut because the fruit pulp is used to make soap. The drupes soapnuts contain saponins, which have surfactant properties, having been used for washing by ancient Asian people. Soapnut is used as a dyeing agent for coloring the yarn of Tussar silk and cotton. It is commonly used to wash hair. |
