Parts Unknown

I've been looking at labels again. It's what I do when I get bored, or when I have to stand in the shower for five minutes to let the hair conditioner work. That, by the way, can be the longest five minutes of the day. Anyway, I generally find it amusing to read labels, particularly on cosmetics, and, my wife loves to experiment with new skin/hair/body/face care products, so we always have some new lables lying around.
I picked up some kind of face cream stuff and right on the front it said "non-comedogenic." I guess that means there's nothing funny about that product. I could look the word up, but my feeling is that if I have to consult the dictionary, then that's not the sort of product I'd want in my home. What I need to find out from my wife is what about the term "non-comedogenic" was so appealing that she decided to buy the product. Maybe, it's just that it was the most expensive jar in that particular aisle at the drugstore.
Then I look at this bottle of hair conditioner she bought, and on the front of the bottle, in big "we're so proud of this" lettering, was the statement: "This product does not contain." Then it began to list a bunch of stuff that the conditioner DIDN'T have in it. As I start to read this impressive list of items, I'm thinking that this could go on forever, because I figure there must be billions of items not in there. But, they're one step ahead of me. After listing about twenty things, such as animal parts (I think), the final item not in the conditioner - "Anything else not listed in the ingredients." Well, there you go. Wouldn't it have been easier just to say that in the first place? And, of course, you'd really only have to say it if you thought a lot of the users of the product are the sort that might think the company would try and slip a few things in on them.
Hey, maybe that does happen. Now, I have something new to worry about. Maybe this company is subtly trying to tell me that most hair conditioners do have animal body parts (unlisted, I might add) floating around in the goo.
I do hope this doesn't become a trend in packaging - listing a bunch of stuff that isn't in the product, that no one in his or her right mind would have ever thought might be in the product, that is until the manufacturer goes out of its way to try and convince you otherwise. I wonder what sorts of parts might be in my toothpaste.
I gotta stop reading labels. I'm getting nauseous.
