    Did you try to make/use it?
    There’s a good discussion about said topic here somewhere. Keep in mind that you can’t dissolve 15% azelaic acid without turning it into an effectless salt.

    azelaic acid is not very soluble in anything - your best bet is to make the product an O/W emulsion with a very polar oil (e.g. a salicylate ester) as the oil phase
