How do Soap Nuts work?
Soap Nuts work like a detergent. They contain saponin, an all-natural surfactant. Conventional detergents are manufactured, chemical surfactants. Surfactants work by breaking the surface tension of water so it can more easily penetrate into fabrics, effectively making water “wetter.” Once wet, the agitation of your washing machine (or your hands) shakes the dirt loose from your clothes. Then Soap Nuts’ saponin holds the dirt in suspension in the water (preventing it from re-depositing on your clothes) until you’ve rinsed it away.
