Couldnt tell ya....works for me. Sizes and holds just fine......I assume because crappo isopropyl alcohol isnt pure its cut with water. edit: The bottle Ive got says its 50 percent (what that means Im not sure). The recipe I used was the easiest I could find, I have since heard of many more, which I have yet to get to.....but I will eventually test them all.
