Hello this is my first post to this forum though I've lurked before. I want to paint with something 100% clear and quite viscous. I added food coloring to transparent dish soap and that is so far the best solution to a clear paint body, but I want to make it thicker. I found a list of common ingredients in dish soap here, and I may be mistaken but I figured if I knew which ingredient is a thickening agent that doesn't increase opacity, I could simply add more of it to the dish soap and get a thicker gel. From what I could find only the PPG (propylene glycol) and alkyl dimethyl amine oxide are thickeners. So I would like to know if any of you know the properties of these chemicals. How transparent are they and how viscous are they? And is it possible to buy in retail quantity? I found PPG on amazon but I'm not sure if it's the right thickness. I found this DOW link and I'd like to get my hands on their thickest product but of course I can't buy in bulk from DOW. I've looked into other thickeners that are clear, stearic acid seems like my best bet and if anyone's worked with it before I'm wondering if I would have to melt it in with soap and generally how it performs generally.
