Sapindus Mukorossi Nuts (Soapnut / Reetha Nuts)

Sapindus Mukorossi Nuts, commonly known as soapnuts (reetha), are a plant-derived raw material naturally rich in saponins—gentle, foam-forming surfactant-like compounds. In cosmetics, they are mainly used as a natural cleansing and mild lathering ingredient, helping lift dirt and excess sebum while supporting a softer, less stripping feel compared with harsher detergents. They are frequently included in “natural” shampoos, scalp products, facial/body cleansers, and botanical cleansing powders, where they contribute to a clean yet comfort-oriented sensorial profile. Because performance depends on extraction method and formula pH, soapnut ingredients are often combined with other surfactants and conditioning agents to optimize cleansing efficiency, foam quality, and overall tolerance.
