Ecozone’s all-natural Soap Nuts are a 100% plant-based, allergy-friendly, economical and effective alternative to common laundry detergent. The 300g cotton bag holds enough nuts for up to 100 washes. Each dose of nuts are also re-usable up to four times. Soap Nuts have been used for thousands of years as a natural washing detergent and cleansing agent. Also known as Soap Berries, they grow on trees of the Sapindus Genus and are a source of saponin, a natural soap which cleans and freshens your clothes at low wash temperatures all without the need for extra chemicals and detergents. They are gentle on skin and fabrics and ensure that colours stay brighter for longer. They are also completely hypoallergenic, biodegradable and compostable. Truly an eco-conscious alternative.
