Avoid This Cosmetic Ingredient If You Are Going to the Airport - EP 34

Are you brushing your teeth with explosives? No, not really, but your cosmetics could still set off alarms going through TSA, and not just because they are bigger than 3.4oz. In this episode we are diving into a cosmetic ingredient that might help with tooth sensitivity, but it might also get you stuck at the airport security checkpoint having your luggage swabbed. Potassium Nitrate, KNO3. In this episode we are diving into some of the primary uses of Potassium Nitrate. We are covering fertilizers, fireworks and filet mignon (meat preservation), and how the oxygen present in nitrates makes it helpful for many everyday uses. Then we are talking about its use in cosmetics. If you have ever used a toothpaste designed to reduce sensitivity, then you have used this ingredient. We are covering how sensitivity relief toothpaste works, and the studies that have proven it to be effective (and of course, poking some holes in them). It's always important to remember that the same ingredient can be used in multiple applications, and will perform differently in each of them. If there is an ingredient in common with fertilizer and your toothpaste, that does NOT mean you have fertilizer in your toothpaste. The concentration and the other ingredients in the formula are always going to be more important than any one ingredient (Unless you are have an allergy) Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!
