Maggie's Soap NutsTM are the only laundry soap that grows on trees! Truly effective, 100% natural and safe for your most sensitive skin. Soap NutsTM are the dried fruit of the Chinese Soapberry tree. They contain saponin, a natural cleaner used for thousands of years to clean clothes, just like the plants used by Native Americans for washing. Simply put a few Soap Nuts into the included cotton sack and drop it in your laundry. Your clothes come out clean, vibrant, and soft. Replace your laboratory detergents and softeners with the soap made from Nature by Nature. Your clothes, your skin, your family, and your planet will thank you. We at Baby Wit vote this hands down the best laundry detergent for baby's sensitive skin. When we tested these out we were amazed at the results. Add a few drops of your favorite essential oil to the bag for a completely wonderful clean laundry smell. After washing with these nuts there is a noticeable difference in the softness of our clothing. We will never switch back to harsh detergents. Gentle on all our clothes. You can compost the seeds after use for 0 waste! From the 10 oz box you will get 35-50 loads clean.
