I have a bottle of vanilla oleoresin from Florihana (EO supplier) that is 75% vanilla and 25% alcohol. However, when I added alcohol to dilute it further to 10%, it looks like it's not mixing at all. When I looked it up in TGSC, it says that the oleoresin is soluble in water but not in alcohol. I'm so confused! Isn't it weird to dilute something in water for perfumery? Should I have diluted it in propylene glycol?
