About Soap Nuts

Soap nuts are found in both the eastern and western hemispheres, but are native to India and Nepal. They have recently become a popular environmentally friendly alternative to chemical detergent, and are a gentle option for those with allergies to chemicals in regular detergents. Soap nuts contain saponin, a natural detergent. The soap nut shell absorbs water and releases the saponins which circulate as a natural surfactant in the wash water, freeing dirt, grime, and oils from clothing. There is considerable discussion as to what variety of Soap Nuts is preferable for use as a laundry soap alternative. Any Soap Nut from the genus Sapindus will work just fine as they all have Saponin producing properties, hence the genus name Sapindus.
