Number of hours your deo lasts (to write on the label)
As an individual seller-that is, not a part of a medium or large company and thus is operating with a limited resources as of yet-
how do you determine how long your deo works (ex, 24h, 48h, 72h), the number of hours you can write on the label if you want to start selling?
Do you have to do a formal, controlled trial with recruited people?
Or is it OK if you just know the rough number based on your sample testing on friends and family if the number of these people is sufficiently large and the effect sufficiently clear to let you know that it is the best guess?

Usually they say UP TO 24h, which means any value but not longer than 24. If you put up to 100000 hours it is still valid, no matter how long it lasts.
Another option is 24 hors *, where the star is “instrumental test” on the back of the label, but what kind of test - not sure. I guess it doesn’t really matter and can be any stupid test

Brilliant.

well in Europe at least you need to make a test like it is described in Phil’s link. You cannot just claim up to 24h you need to have a test if you want to write any number on it that shows that a trained pennel does not sniff out any sweat smell on a Test pennel over the time you want to mention on your deodorant.
OFcours you can get through as long as your safety assessor does not want to see the test but normally they will kill the claim if it is not somehow tested.
