All out in the wash
It’s time to dig out those old soap containers, or head to the charity shop to find one. Ethique offers compostable storage containers. Make your own. Cold-process Soapmaking Kits from gonative.co.nz are a great place to start. But be aware that soap contains caustic soda (NaOH) aka sodium hydroxide, also known as lye. Soap cannot be made without it. Caustic soda can burn your eyes and skin so treat it with great respect. Glasses or safety goggles and rubber gloves are a must, and a face mask is recommended. Soap needs oil, water and alkali or lye. Soap calculators are essential for a safe product. A safe soap is between pH 8 and 10.
