Soapnuts are 100% natural substitute to normal laundry detergents. They contain natural saponin that is released in warm water. Soapnuts can be used for machine laundry for all textiles, including wool and silk. Using soapnuts will not wash out colours of your coloured laundry. Soapnuts are suitable for people with allergies and dermatological conditions as they do not leave chemical residues in your laundry.
