    You do not allow concentrations used here so it is nearly impossible to help you. If there is less than 25% total of those many polar oils I would try a polyglyceryl ester such as polyglyceryl-6 oleate, polyglyceryl-6 hydroxystearate…a combination works best along with a “buddy ester” like sorbitan oleate, glyceryl stearate citrate, lauryl glutamate. Good luck with all that expensive peptide.

    How exactly do you think this formula will stay stable without an emulsifier? Maybe I missed it, but I don’t see one here.
