I could really use some help on a formulation that keeps forming precipitation no matter what I do! I’m no chemist, but I’ve gotten pretty good at formulating and just cant fix this. I took a course on formulating this particular serum and the instructor seems to have left something out! I believe the SD is super sensitive to lower PH…everything is just peachy until I lower the PH. Can someone help PLeasssseeeeeee??
Sodium Deoxycholate 1%
Distilled Water 93.5%
Caffeine Extract 5%
I’ve tried various combinations, omitted, and added ingredients to include glycerin at the proper percentages. No matter what when I attempt to adjust PH to right around 5 the solution is fine for a short while and then begins to form precipitation. Im confused and this is driving me nuts! 🙃
