Propylene Glycol Dibenzoate in Lipbalm

What solvent would be best to incorporate propylene glycol dibenzoate (polar) to an anhydrous lipbalm?

    Pretty sure that diester is lipid soluble so it may not need any co-solvent, depending on what "anhydrous" components you have in there. If using a lot of it in your formula, solubilize/stabilize with C12-15 alkyl benzoate. (What CAN'T Finsolv TN do, I always ask?)
  • @chemicalmatt
    Thanks! :-) Would caprylic/capric triglycerides also do if it has to be a polar oil?
    The rest of the ingredients are: Jojoba Oil, Argan Oil, Beeswax, Candelilla Wax, Shea Butter, Tocopherol, Bisabolol (and coloured mica's).

    MCT should work OK, but I'll add that Finsolv TN is a far better extender/wetting agent for mineral pigments than anything else in there.

    You're right, I'll get C12-15 alkyl benzoate with my next order. Thanks!
    And I will try testing its multifunctional properties in other formulas. ;-) 
  • I am making a similar lip balm but I am trying to make it tingling.  I used cinnamon LEAF Oil (not Bark Oil). And the tingling starts slow and doesnt last. I put 2% in and it still last very long... any suggestions?

    I have no experience with cinnamon in lipbalms. Maybe others can help?
