  • BEST GELLING AGENT FOR BHA SERUM?

    Posted by cosmetic_chemist_vietnam on February 29, 2024 at 8:21 am

    Hi everyone, I am making Salicylic Acid 2% Serum and Salicylic Acid 2% Gel. I need a gelling agent which is stable at pH approximately 3.7-3.8. Could anyone give me a suggestion?

    (I know xanthan gum is stable at that pH but I don’t want to use it because it’s sticky. I see L-Ascorbic Acid 15% Serum of SkinCeuticals using Sodium Hyaluronate as a gelling agent. So I want to try it or Hyaluronic Acid, although some information I search tell me these gelling agents aren’t stable at pH < 4.)

    Have you tried better grade of Xanthan Gum? There are fantastic grades, not slimy, not sticky, transparent/translucent …

    I would try Sepimax Zen.

    Also if companies are using Ascorbic acid, the pH is probably low ~3.5 … and if they do use Hyaluronic acid, it must work, right? Ascorbic acid also oxidates quickly, so the stability is probably not the main problem. Use some HMW and see how it goes.

    Hello!

    HMW HA, Xanthan Gum (try Xanthan Soft, it doesn’t feel sticky at all) and Sepimax Zen would be your best friends, all of them can handle low pH.

    Have a nice day!
