Sodium percarbonate from Droguerie Ecologique is an excellent bleaching agent that's ideal for keeping your laundry naturally white by helping to prevent the greying of fabric from limescale build-up. Also referred to as an Oxygen Bleach, sodium percarbonate is a powder made of sodium carbonate and hydrogen peroxide that sounds like a nasty chemical but that breaks down into water, soda ash and oxygen when dissolved in water. When used as a natural stain remover, it quickly and completely dissolves a wide range of stubborn stains, including tea, coffee, red wine, grass, fruit stains, sweat and blood leaving behind no environmental impact. As well as having a number of uses around the home, it is also an excellent product to use to kill bacteria, fungi, mildew and viruses so can also be used outdoors as a moss killer or for controlling algae in standing water.
