Triethanolamine & AHA’s
Hello Everyone! I am curious how much TEA is normally needed to raise the pH of a product.
Created a toner with 8% Lactic/4% Glycolic acids (active %), which read a pH of 2.95 with 2.5% TEA, and a pH of 3.4 after 5% TEA.
I am trying to maintain a pH level of 3.6-3.7, and was just a little surprised how much TEA was required for this specific formula.
Using an Oakton pH Testr 30, which is calibrated.
Thanks in advance!
