ascorbic acid and gasses build up
Hi everyone
I am requested to formulate an ascorbic acid 15% in water. It is a runny serum with no thickener. I have around 30% water and around 38% combined propanediol, dipropylene glycol and Dimethyl isosorbide. pH is around 3.5 .I don’t have any issues with recrystallisation. The issue I have is at 45C after 1 month, in a glass packaging with pump, the formula produces too much gasses that it shoots out upon pumping. 25C samples are perfectly fine. Any idea how to help reduce the gasses build up. TIA
