What metrics are deoderant companies using to calculate their "72hr protection" numbers? - eviltoast

How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?

Im assuming they’re fudging their numbers but at what point does it become false advertisement?

    First there was the 12h deo !!!

    Then magically the same was 24, 48 and eventually 72?!

    There was a backlash against that 72 hours in some countries like do you even shower bro?

    Soon 1 month smell free!1!!
