Like another reviewer, I use this along with washing soda, baking soda, and borax to make homemade powder laundry soap. When grated, it dissolves completely in the wash, leaving no clumps behind. My clothes come out very clean, it doesn't fade them or break me out, and because it leaves NO residue there's no dryer static either! They come out fluffy and smelling fresh without using gunky fabric softeners or dryer sheets, it cuts right through hard water too. The soap doesn't foam up big in the washer like chemical detergents will and doesn't leave a film behind either, which makes it great for front loading HE washers. It makes a good stain stick for pre-treating grease and lipstick stains on clothes if you moisten the stain then rub the bar on the stain. It also dissolves well by itself in water (grated) to make a vegetable-safe soap spray to deter garden pests and powdery mildew. I tried this on skin, and it cleans very well, although it is a little drying to skin which is already sensitive and dry. It would be best for normal or oily skin as a bath soap.
