Hi Neversure,
I don't think you will get a low ph with handmade soaps unless you add something to lower it, it is naturally about 10. I don't test the PH, been soaping for 10+ years now. check to make sure it is not lye heavy, I use the tongue test, heres how, wet finger rub on soap, gently take finger to tip of tongue, now be careful, if it is lye heavy it will make your tongue tingle (we call it zap)it can do this even before it touches the tongue, if there is no zap it is safe to use.
Can I ask if you use a soap calculator to work out the lye for your oils? and do you add extra oil (superfat)to make sure you don't get lye heavy soaps.
