What if the ph is too low or too high? Pitera 50% 4MSK 3% Active Resveratrol 5% EDTA 0.2% สารนำพา 2% water 39.3% : สารกันเสีย 0.5% Thank you. I'm about to order, if I'm missing any of them, I'll be able to order together.
Hi, to lower the pH you can add a weak acid like Lactic Acid , Citric Acid for adjusting the pH value to be higher, can add weak alkali such as Triethanolamine
