FAQ
Deodorant and Antiperspirant Testing: frequently asked questions
Where does Validated Claim Support test deodorants and antiperspirants?
Validated Claim Support tests deodorants and antiperspirants at its FDA registered drug testing laboratory in Teaneck, New Jersey, with human volunteers recruited in the Bergen County area. Participants apply the product and work up a sweat through controlled exercise or by sitting in a temperature controlled hot room.
How is antiperspirant effectiveness measured?
Sweat patches collect perspiration from the skin before and after the antiperspirant is applied, and technicians weigh them to evaluate how much the product reduced sweating.
How is deodorant odor protection measured?
Panels of experts rate odor on defined scales, taking into account intensity and the duration of odor protection, and can compare different scents to see which lasts longer or performs better in sweaty conditions.
How are deodorant and antiperspirant regulated differently?
In the United States, antiperspirants are regulated as over-the-counter drugs by the FDA, so their claims must be supported by scientific evidence. Deodorants are classified as cosmetics and face less stringent FDA regulation, but must still follow guidelines on truthful advertising. A product can make claims as both.
What deodorant and antiperspirant claims can VCS help support?
Validated Claim Support can help support claims such as "Up to 24 hours odor protection," "Up to 48 hours wetness protection" and "Wetness control for up to 24 hours," along with safety testing so products do not cause rashes or irritation.
Does VCS test on a diverse group of people?
Yes. Everyone sweats differently, so Validated Claim Support tests on diverse groups of people to make sure products work across a variety of skin types and sweat patterns.
