Hello, So Ive been using polysorbate 80 at 1% along with 1% essential oil in my liquid soap. With peppermint essential oil it works great! My soap is clear! However, with my own blend of pink grapefruit, lemon and orange essential oils it still manages to separate, cloud and have a large layer of white fall to the bottom. Can anyone recommend how to stop this? Is it due to citrus oils? Should I use a higher % of PS80? More information on PS80 and essential oils for liquid soap would be much appreciated. Cheers!
