If you have ever been bored enough with the taste of water that you added an “enhancer” to it, perhaps you should read on. There was a conversation at work today that went something like this:
Dan: What are you squirting into your water bottle, Kelly?
Me: It’s a water enhancer.
Dan: Let me see what’s in it.
Me: OK (as I hand over the bottle of purple stuff)
Dan: (after scanning the label) Look, the third ingredient is propylene glycol. That’s antifreeze!
Me: That can’t be. I’ll google it. (time passes after visiting Google machine) You’re right. Wikipedia says that antifreeze is made of either ethylene glycol or propylene glycol.
Dan: Ha, you are drinking anti-freeze.
Me: Ya, but it’s only the non-toxic kind, and it tastes good.
As of this post date Wikipedia lists many uses for propylene glycol, including food coloring/flavoring and nontoxic antifreeze. Brilliant!
