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?
“Im assuming they’re fudging their numbers”
yup.
“at what point does it become false advertisement?”
liability/conviction.
Burden of proof.
If the least smelly person on the planet can use the product and stay fresh for 3 days, technically they aren’t lying.
They also usually use some weasel words like “up to.” That way, if it doesn’t last the full 72 hours (which it won’t), they can claim that they stated “72 hours MAXIMUM” rather than just “72 hours.” It’s basically shifts the statement from “lasts three days” to “definitely won’t last four days.”
Lots off stuff like that out there. Like food products that say “Made with 100% white meat chicken”. That just means that 100% white meat chicken is one of the ingredients.
Or those stupid “99c and up” stores. That’s no dollar store. That’s just a store. 99c and up is so many things.
Or the american no sugar rule that makes 100% sugar tic tacs sugar free (each ‘serving’ contains less than 5 gram of sugar)
