Dermatologist-tested hypoallergenic formula uses soap flakes and natural salts to break down dirt, stains, odors, microbes, and comes packaged in a 100% plastic-free box. Unlike most laundry pods, detergent sheets, and poly-lined cartons, which can leave behind microplastics, our box is clay-lined and totally recyclable. Safer Choice Certified formula is independently tested to clean as well as stuff in the big plastic jugs.
