Important points to remember
When you are using it for Cold Process soap making, remember to always add the Sodium Hydroxide to the water and never the other way round. It is often mentioned to not use hard water for Cold Process soap making and so why not consider using Distilled Water which is readily available in DIY shops or Car Spares Shops.
