Wired tells us another wonder of the world: what's inside shaving cream. Here's some of the gory details - man, I love this stuff:JG• Isopentane: In shaving cream, this degreaser breaks down sebum, the oil your skin produces. (It also smells like gasoline.) That helps whiskers stand up, the better to mow them down with a razor.
• Sunflower oil monoglycerides: This plant oil has seemingly magical properties. Its fatty acids attach to a carbon backbone and keep the product in gel form. But rubbing the gel in your hands introduces air. Voilà: foam.
• Sorbitol: In food, this sweetener causes diarrhea. (Luckily, shaving cream is not for eating.) Here it's a cheap stand-in for glycerine, a skin moisturizer.
