trying to hunt down info on the silica that I used to buy for the scrubs.....want to start making small batches to see if I can perfect the recipe. Just want to try to get a website up and running and try to make. My recipe doesn't separate like most, it's much more manageable and by adding just a touch of water before applying, it's really smooth going on and rinses releatively clean. It doesn't leave the greasy layer on the bottom of the tub like most scrubs.
