Is your colon all gummed up with old food that you can’t seem to get rid of? Well, if you think it is—probably because some advertisement told you so—there are plenty of colon detox products on the market. In the June print issue (and online), Consumer Reports looks at the possible health benefits of colon detoxing and determines that it’s not necessary, mainly because waste doesn’t build up in the intestine in a way that would require some sort of flushing in the first place.
Hey, do you know what’s in Nair, the creamy hair-removal product that smells like skunks? (Or used to—the current formulation is supposed to smell better.) Now, thanks to Wired’s “What’s Inside” article, you will! The active ingredient is potassium thioglycolate, a member of the thiol family, which not coincidentally is also responsible for the intense stink factor of skunk spray. Thiols “eat into keratin (a skin and hair protein), which is what makes actual skunk spray (and Nair) lock onto human flesh and fuzz.” Another chemical—calcium hydroxide—destroys the weakened hairs.
