Making a peel serum
Hi
Iam making this formula
10% glycolic acid
2% salicylic acid
40% propylene glycol
3% glycerin
1% phenoxy ethanol
0.3% sodium hyaluronate
I Am dissolving salicylic acid in propylene glycol with heating
In separate container I’m adding sodium hyaluronate with water until it dissolve.. then i add everything gradually
Once i try to adjust the ph ( with tri ethanolamine or sodium hydroxide)
It thickens and form a gel
What is wrong in this process and how to fix it
