What are Soapnuts? They are not nuts for a start. They are apparently berries. With a small black seed inside. What we are interested in is the outer shell which contains saponin as a protection against fungus and bacteria. Saponin just happens to be a natural surfactant (detergent). The presence of saponin in a shell in not that unusual, a little research will show you that many trees give some (the horse chestnut for one). It is just that the Sapindus family has more than most.[[Category:Dandruff
