Origins: Trying to get to the bottom of this claim, I dug up a couple of newspaper articles about Carmex. One long article from 1995 turned out to be a collection of quotes from various women who professed to be addicted to it. Nothing tangible or verifiable (no chemical analyses or anything like that), just a collection of quotes from ladies who claimed they couldn't live without it. It's stories like these that add to the spread of rumors, because at first glance they appear to authoritatively confirm the half-remembered stuff whispering around a person's head.
Apparently the article's writer had gotten in touch with the manufacturer of Carmex, because the piece included one quote that could be considered as coming from a "source":
Yes, there were
In other words, nada. A fluff piece, nothing more.
A better-written and slightly less slanted article on Carmex appeared in 1993. Though clearly meant as a tongue-in-cheek piece, it does mention one well-known vector for the "Carmex is addictive" story: Paula Poundstone.
Carmex is a cold-sore and chapped-lip salve that was invented in 1936. It is made mostly of menthol, camphor, alum, and wax. As Carmex junkies know, this yellow moosh is not just another lip balm. Carmex packs a kind of rush for the kisser. Once you've felt this rush, it's impossible not to want it again. And again. And again.
"The jars are kind of our trademark," said Paul Woelbing by phone from Carma
Woelbing (pronounced WELL-bing) knows all about Carmex junkies. Every day, mail arrives at the lab from people wanting to know if there is an addictive ingredient in the stuff.
"One common suspicion is that we put a really terrible acid in it that roughs up your lips and makes you need more Carmex," he said. "But the acid we use is salicylic acid, which is aspirin. Another rumor is that we grind up fiber glass and put that in."
At 36, Woelbing is the treasurer of Carma
A practical man, Alfred Woelbing created Carmex because he had cold sores. He called the lab "Carma" because he liked the sound of the word, and "ex" was a very popular suffix then.
Never in Carmex's 57-year history have the Woelbings advertised or marketed their product - unless you count "the $10 a year we spend for my dad's vanity [license] plate," said Paul.
