I am a long-time a convert to the soapnut craze. I first noticed these little fruits in Burma/Myanmar where they use them in their traditional shampoo. A couple years ago I discovered that their popularity has really grown in Western countries and now you can spend top dollar on powdered soapnut laundry soap and other commercial products. The best way to use these berries from all perspectives is to simply use them as is in your laundry, or to make them into laundry detergent (see below). Powdered soapnut berries are not really a viable product and anything that has things added to it to make the shelf life longer is a step in the wrong direction.
