 Soap nut (Sapindus emarginatus) leaves.
Sapindus emarginatus is an economically important tropical tree species sparsely distributed in different geographical provinces like Gangetic Plains, Western Ghats, and Deccan Plateau in India.

The drupes (soapnuts) contain saponins which are a natural surfactant. They have been used for washing for thousands of years by native peoples in Asia as well as Americnas. Soapnuts are being considered and used for commercial use in cosmetics and detergents as well as many other products.
