I bought a bottle of Glycerin from a local super market. I looked at the ingredients to make sure it was at least 99.5% glycerin, which it is. The label shows its a Skin Protectant. It does show that it is USP, not sure what that means, but I was told it needed to be that. I was searching for Glycerin and came across a kind at Joanne Fabrics. It stated it was to sweeten frosting, or something like that. Does anyone know if the kind I bought will do the job? Thanks much........
