Once I found myself reading the ingredients on a bottle of hand lotion (it was a slow day) and I noticed that one of the ingredients was something called urea. I looked it up because it sounded nasty. Here's the definition: "a soluble colorless crystalline compound contained especially in the urine of mammals." Blah! Why do we need mammilian urine derivatives in our lotion? What real purpose does it serve? Do I really need mammal urine on my hands to keep them soft? And what's going to be next, finding out my shampoo contains hippo dung?
