if the word triclosan doesn't at least sort-of-kind-of ring a bell, I think you need to get out more. :)
triclosan is an antimicrobial.
and a pesticide.
and approved for use by the FDA.
it is also a skin, eye and respiratory irritant.
you find it in shampoos sometimes. and in hand soap and sanitizers.
and even in kitchen utensils, toys, bedding and socks, to name a few.
and it is VERY TOXIC to aquatic organisms. when exposed to sunlight, triclosan forms dioxins. go read about 'em. they are very, very, very bad.
some scientists believe it may contribute to the rise of drug-resistant bacteria. I agree with them. if you want a more neutral point, check out what this fella has to say. but in any case, it's like what I tell the people who think global warming is a hoax--okay, fine, let's pretend it's a hoax. is putting less pollution into the world a BAD thing? yeah, that's what I thought.
just in case you're still not picking up what I'm putting down--so, the sides are stacked, and triclosan looks pretty bad...but maybe it's not, like horrifyingly bad. I mean, it isn't lethal, right? Not to humans, anyway.
But, do you really want to put a skin and eye irritant INTO YOUR MOUTH? And do you really want to kill the fishies and pollute our waterways every time you brush your teeth? I mean...put toothpaste on brush. brush your teeth. spit. rinse. spit. right?
where does that water go? down the drain...where it gets to the wastewater treatment, eventually, right? and they can't get out all of the triclosan (which ps, that water is often exposed to sunlight as a part of treatment, did you know that? hello, dioxins.
maybe that water is used for city water at some point. maybe a fish swimming in that water is your dinner in a few months.
maybe you should get new toothpaste.
and maybe we should stop supporting all this damn germ hysteria.
(note: I get that with the sw!ne flu and all that germs are a huge deal. but it's nothing that a 30 second hand wash with soap and hot water wouldn't fix. I mean, hand sanitizer? everywhere? in addition to hand washing, even? yikesies.)
