When did Soap change its name?

When did soap become Body Wash?
At the same time that mankind is evolving, we are devolving our language use.
Now, the stuff you get clean with is named for it's intended use, yet this new name evokes the primal being in me. I feel like a grunting caveman when I say "body wash". Reminds me of this guy I used to work with who one day announced to a group of guys in the men's room that he needed to buy our company some ass wipe.
