All our products are designed to be safe for the consumer and the environment, when used as intended. The wastewater from the washing machine can contain all sorts of materials, from the dirt removed on your clothes, ingredients from your detergent and actives from the fabric enhancers. After washing, the used water (including dissolved product and dirt from clothes) enters the sewage system and is treated with other household wastewater in a dedicated treatment facility, where dirt is removed, biodegradable ingredients are broken down, and the water is cleaned to help protect aquatic environments before it is released.
