UPDATE: Since we filmed this video, the FDA has banned triclosan and 18 other ingredients from “consumer antiseptic wash products” (aka soap). You can read the details below, but the FDA is basically saying that none of these ingredients clean your hands any better than plain old soap and water. The FDA did not ban triclosan from toothpaste, but you can easily check whether your toothpaste has it by checking the ingredients label. Triclosan would be listed under “Active Ingredients” in the “Drug Facts” box on the back of the package. Most toothpastes don’t have triclosan, so you can choose to brush without it if you’d like.

About Ingredients:
Join MIT-trained chemist and science educator George Zaidan as he tries to recreate everyday household products like toothpaste, lipstick, or shaving cream using only natural ingredients… and no recipe! He’ll have to decode long lists of intimidating chemical names, figure out what they all do, try and find natural substitutes, and then cook up the do-it-yourself versions in his chemistry lab (kitchen). While George may or may not succeed, we'll all learn something new and surprising about the products we take for granted every day.
