The EcoEgg laundry egg is a complete alternative to detergent or washing powder. You simply put it in the washing machine and you don't need any other detergent. The two types of mineral pellets contained in the egg go to work and produce powerful (but natural) cleansing foam that thoroughly cleans your clothes. These are refillable.
In addition, EcoEgg has been dermatologically tested and found to be extremely suitable for (very) sensitive skin. EcoEggs are stamped 'with permission from Allergy UK' and are a money-saving, environmentally friendly and hypoallergenic alternative to regular laundry detergent.
