Suitable for all coloured and white garments made from cotton, linen, hemp and blended fabrics that can be washed at 40-95 degrees. For optimal washing results, use washing powder with water softener (in hard water areas) and bleaching complex. The main ingredient of Sonett washing powder is pure organically certified vegetable soap - the most natural cleansing substance for man and nature. In contrast to all other detergents, soap immediately combines with the calcium that is always present in waste water and neutralises itself completely in 3 - 4 days. 100% biodegradable. Sonett Laundry Powder - 1.2kg is part of the range of Sonett natural laundry products.
