Sodium Polyacrylamide

[frosch45]

well, that's one name at least....

 

I was just going around the web looking at some chemistry stuff and I came across a website selling "Sodium Polyacrylamide"

 

Apparently, it is used in those collars that cool you down and that you wear around your neck.

 

I was wondering if anyone had any additional information. Does it have the same basic affect as ammonium nitrate does when it dissolves in water? Or is there something more happening?

 

No wikipedia page, grrr.....

 

thanks

I think they are refering to this

 

http://en.wikipedia.org/wiki/Sodium_polyacrylate

or its copolymer with acrylamide

the stuff soaks up water like a sponge so I guess that its just the water evaporating that provides cooling.

Thanks

 

I was gonna say, a chemical without a wikipedia page!?

 

Well, of course there are some, but I wonder if I should trust these guys. I mean, if you mispell the name, it really shows how much they know about it... how good a quality of substance that they are selling....

Watch out for acrylamide. In it's non-polymerized form it is a neurotoxin.

You forgot to mention that it's difficult to avoid as it's present in lots of cooked foods.
