ORIGINAL: DarkSteven The link is pseudoscience. Most links are. quote:
Molecular weight? Gimme a break Chemical affinity determines whether something will be absorbed or not. Weight simply indicates is a secondary factor in the speed of uptake. Sort of, but beside the point. What's interesting is whether it does anything, and whether our bodies can cope with it if it does. And that is a question that nothing short of statistics will tell us, which is why statistics are required for anything to be used in domestic products in large parts of the world. quote:
If something is water soluble, it will pass through the body. If it's not, it will accumulate in fat. That means the liver. I don't know if the heart has a layer of fat, but I'm sure the brain doesn't. Stuff that finds its way to the liver generally finds its way out of the liver and into the feces. The brain, incidentally, is primarily composed of fat and water. quote:
Emphasis mine. Claiming that trace amounts of a chemical could have the same effects as a megadose of it is ridiculous. While worrying about SLS is probably ridiculous, this argument is not up to spec. If you're wondering why, look up the chemical agent MPTP, or the biosynthesized supplement L-5-HTP. And, of course, almost any process that creates a useful compound has the potential to introduce contamination. It is a testament to the maturity of these processes that we don't die like flies from taking aspirin or sprinkling sugar on food. People who worry will always find something to hang their worries on. Fear is not a rational beast. It is a response that's meant to keep us out of trouble. Problem is, it is tied into the "higher" functions of the brain, too, so that it can be triggered by conscious thinking. Fear is readily triggered by the unknown, but this extension unfortunately makes it possible for the unknown at a conscious level to trigger our fears, including our own limited understanding of all this "newfangled stuff" out there. Keep in mind that, to the average person, the remote on the TV is magic. When it stops working, you slap it, try again, slap it again, try again, maybe change the batteries and repeat the process, then call the guy who knows shit: the repair man. The wizard. It's magic. And so is SLS, unless you happen to be the wizard. But some of us can learn enough to check the statistics, which obviates the need to know the details. And as far as I'm aware, the statistics point at SLS as a dermatological concern, not a real health risk. My scalp doesn't appreciate it on a regular basis, so I use a highly toxic shampoo instead. My hands don't mind it, though, so I use a common soap for those. Neither has proven a problem so far, though. Health, al-Aswad.
