Hello , I have a question. So how do I know the concentration I need and also the amount of glycolic . For instance I need 2% glycolic in my formula out of 70% concentration, how many grams would I be needing ?
Your supplier should be able to provide the usage rate of the glycolic acid. Thank you for watching.
