  Posted by Rana_91 on December 15, 2023 at 2:04 pm

  Hi guys

  I Am trying to make a bha aha serum the formula:

  10% glycolic acid

  2% salicylic acid

  0.8 HMW hyaluronic acid

  Sodium benzoate as a preservative and triethanolamine to solve salicylic acid

  But the formula is too alkaline… The ph is almost 10 … What to do to make it acidic can you help?

  Full % and Methods would help. Triethanolamine is used in pretty low concentrations- is it solubolizing the salicylic acid at 2% PG would work with a bit of alcohol. SA should also bring the pH down..maybe try some citric acid?
