All Earthwise products are free from phosphate, ammonia, nitrate and chlorine, but why? Phosphates, ammonia, nitrates and chlorine can be both safety and environmental hazards. Plant-based ingredients are pure, natural in origin and environmentally sustainable. Our ingredients are carefully selected to be gentle for you and your family, as well as the environment - rapidly degrading without causing harm. At Earthwise, we figure we want to make a lasting impression in your home, not on the environment.
