I have used it, but I didn't like it. I used it with a yummy pineapple fragrance oil from Peak that is 4% vanillin and 6% ethyl vanillin. Without the stabilizer, my soap was chocolate brown with the fragrance. With the stabilizer, the soap turned a muddy yellow color, but the edges were brown. The fragrance completely morphed and didn't have the lovely bright scent any more. For me, there is no point in using it if the fragrance changes.
Maybe someone had a better experience than I? I was realy sad it didn't work for me.:sad:
