    Does anybody know any natural oil which won’t go together?
    I need to make a duo phase formula but couldn’t find anything.

    Thank you

    @Shannonho First you need to define what you think of as Natural.
    If you are thinking vegetable oils, then they are generally compatible, if you want to non-miscible oils you will need to find a non-polar oil with no hetero atoms (O & N) and a polar oil (Vegetable Oils & Esters).

    @Sibech Thank you so much for your answer, I’ve tried many different kind of oil, but no one seems to work, most of the oil/ester they seems to be together very well, do you have any oil suggest that I can try? Thank you so much

    Parafinum Liquidum (Mineral Oil) and Vegetable oil would be an example. I don’t have any “natural” non-polar oils in mind, but if you do the searching I know you can find non-polar oils.

    It happened with me once, castor oil and laurel oil are not miscible for some reason. Hope this info is useful

    Thanks for the information. the hardest part of this project is I am not allowed to use mineral oil and castor oil….I need to try more about “good” natural oil.

    Complete waste of time. You will never be able to do this. Still, as long as they are paying you… the nearest you could get would be to use oil mixed with alcohol, you’d have to use an alcohol that can be diluted to have the same density as the oil.
