Is castile soap irritating? Looking at making my own soaps
I'm looking into making my own soaps for several reasons (liquid hand soap, body wash, etc). I could easily add more hydrating oils into it, but most of them ask for a small (!) amount of Castile soap. I know everyone is different, but does anyone have any feedback on this? Is it inherently irritating? Looking in particular at one of Dr. Bronner's, but doesn't have to be theirs.
I only have one experience using it as a body wash, and I remember my skin being horrifically dried out and itchy for a while afterwards. However and with that said, that was a long time ago, and I don't know whether the person who'd supplied the soap diluted it properly or any of the other details.
