Not the ph. For that you'll need something more complicated than the strips.Yep. Guess my question is if the Zap test is the best way to test the PH in your soap?
Thanks folks!! Zap test it isEven a small amount of excess alkali is enough to really bother your skin, even normal skin. If you want to know simply if there is excess alkali or not, the quickest and most accurate "yes or no" test is the zap test.
If you want to know exactly how much excess alkali there is, a person would need to do a free alkali test. This analysis is a LOT more sensitive and precise than a simple pH test. There is no way a simple pH check can do this job.
