Hello, I've been making a few different batches of soap, running them through a lye calculator, following the recipes religiously, and yet they seem to be harsh on my skin. I have done the zap test...nothing. But when I test them with the ph test strip from the drug store, they come out with a very high ph. I am testing soaps made from hot process, cold process varying from 2 weeks to 6 weeks old. They all seem to come out high...turning the strip a dark purple, which I've read means very high...I have no idea what I'm doing wrong. Any ideas?
