    Hi MarkBroussard,

    I am looking for formulating services for a CBD nano emulsion topical using a BSP-1200 Bench scale model from Industrial Sonomechanics I recently purchased and wonder if your are available to work with me on developing a formula that will result in a stable and preserved product. The ultrasound I purchase will create particle size of <100nm, so I need to make sure whatever other ingredients I add the size will not be adversely affected. I am WA State licensed i502 producer/processor. 

    Thank you,
    Tami Mendonca

    Hi Mark, I forgot to indicate you how i arrived to avoid crystallization of azelaic acid in chemical peel. So in fact it is not a matter of solubility but of recrystallization.
    In fact i add the alcohol, about 6% prop glycol, 6% water, I add the azelaic acid and warm up till the first boiling bubbles comes. I stop heating. And no more problems. I guess the solution must arrive to a certain temperature to avoid re-crystalization. After i made stability at 5 and -15C and no more issues. Bye

    Hi Mark, this is Rebecca.  Thank you very much for your help.  When you mentioned, 0.3-0.5%, does it mean e.g. 50 ml of deodorant solution, I should add 0.15 ml to 0.25 ml of Xanthan Gum powder?  Sorry for this stupid question :)

    I read your post about using Konjac Root Powder as a gelling agent instead of carbomer. How do you use this ingredient? I have tried using it at 1% and 0.80%, and they both caused roll/rub off when applied to the skin. I heard that I should use less to prevent this roll/rub off. Should I use less and add another thickening/gelling agent?
