Soap nuts, also known as Sapindus mukorossi are native to India and Nepal. They are not nuts, but actually a fruit, a berry to be specific. However, when you dry them, it forms a hard outer shell that looks like a nut. The shell contains saponin, a natural detergent. Saponin gets released when the shell absorbs water, it also softens your clothes. Soap nuts are a great alternative for people with allergies who need a chemical free detergent.
To use soap nuts you would need to put about 4-6 of them in a muslin bag and then toss it in your washing machine with your laundry. If you prefer a scent just add essential oils to the muslin bag before tossing them in. Soap nuts don’t create a lot of bubbles and can be used several times before they break down. They are very eco friendly and cost effective!
You can also use soap nuts to make facial washes, shampoos and natural soaps. I found quite a few site online that sell soap nuts. So I’m going to buy some and see how it goes.
