Hello
Hope you are having a good day
So i am trying to make a vitamin c serum using sodium ascrobyl phosphate formula is
Sodium ascrobyl phosphate 5%
Hyaluronic acid 0.5%
Glycerin 0.5%
Propylene glycol 1%
Citric acid (to adjust ph)
Hyaluronic acid gives natural thickness to serum to no need of gums or thickener
The problem i am facing is after some time like a month i i can see some net like white substance is formed like we wet a tissue with water and sticks to walls of bottle its concerning
Using propylene glycol as a preservative since don't have many choices
Attaching the pic of available ingredients
