for topical gel formulation which one is the best choice to increase pH from 6 to 7?NaOH 0.1M or TEA(triethanolamine)? which one can cause less toxic effect after long term administration?TQ
If your pH meter is very sensitive, use 0.1M and 0.01M NaOH. start by using 0.1M, when approaching pH 7, you can now use 0.01M not to overshoot pH 7
Thanks
