fruit of Sapindus trees containing natural cleansing saponins
Soapnut, also known as Reetha or Soapberry, refers to the fruit of trees in the genus Sapindus. These fruits contain saponins, natural surfactants that create a lather when mixed with water, making them effective for cleaning and washing. Soapnuts are often used in natural hair care products for their gentle cleansing properties and are considered an eco-friendly alternative to synthetic detergents.
