Soap (Not Fight Club)

I wondered if anyone knew a relative percentage% of water soluble materials we get on our hands, or rather, how useful is soap unless you work with chemicals/cars/ect. everyday?

I’ve stopped using it for ~2 weeks and I’ve noticed I don’t feel as dry or tense. Especially on my hands, because all my hangnails have gone away rather quickly.

Any related information would come greatly appriciated.
