How Do Deodorants and Antiperspirants Work?
Season 2
Episode 45
Reactions is getting into some stinky science. We're looking at the chemistry of body odor and how deodorants work. If there is one thing everyone on Earth has in common, it's that we all absolutely stink. Luckily we have deodorants and antiperspirants to help us get over that fact, but chemically speaking, how do these products actually work?
