Jan, As a matter of fact, yes you can use EZ soy, but only because it is 100% pure soy. You cannot use any of the blends. You will also list it as Hydrogenated Soybean Oil. I called my main wax supplier today and found all this out. You will have to "play" around with the amounts, because it will make it very thick. Oh, and by the way, THANX AJ
