Remember this? http://jenorasoaps.blogspot.com.es/2013/10/ph-in-handmade-soap-shampoo-bars-citric.html
As a follow up, I just want to let you know that after 5 weeks of curing, the pH of this soap/ shampoo bar, is no different than my other bars without Citric Acid. It has not brought the pH level down.
The shampoo bar is okay, but I actually prefer my bars without it!
It was an interesting experiment, although I have so many other things to experiment with... so will probably not be focussing on this right now. I remind myself that I am not that concerned with lowering the pH in my soap bars as I am okay with where they are.
Has anyone else out there tried this? With what results?
