Hello everyone my name is Marco, I was about to buy MinoxidilMax but then by reading on the ingredients I see that they only list:
Azelaic acid 5%
ABN complex 0,8%
Retinol 0.025% (0.25 mg/mL)
Caffeine 0.001% (0.01 mg/mL)
The solvent ,they say, is PG (propylene alcohol).
Now, I know that the solubility of minoxidil in PG is maximum 5%. I know because the pharmacy where I get my freshly made galenic minoxidil uses PG as a solvant. One day I’ve asked them to make me a 15% concentration and they told me that the solubility of minoxidil in PG doesn’t go over 5-6%, a fact that I’ve confirmed by asking to the pharmaceutical house that produces their PG ( they use a PG branded “espumil” , made by Fagron pharmaceutical ) .
Knowing so, I have asked to the MinoxidilMax guys what is going on, and here what they’ve said:
Even if you use a solvent that is the same as Rogaine (meaning same solvent and same ratio of alcohol, water and PG), you can easily get up to 6%. However, when you add azelaic acid, it greatly enhance its solubility. Of course, we have some other tricks to further enhance the solubility to get 15% minoxidil."
Doesn’t it smells BS to you?? Like “of course we have some tricks”… Aren’t they obliged to list their “tricks” in the ingredients list?? Does azelaic acid really enhance the solubility of minoxidil? Never heard it before…
