Title: KNO3 can be found in toothpaste?
Post by: Naufal the B. S. on 02/08/2009 09:58:10

This thread is continuation of my "mess" thread, it is "soil with high nitro..."

I've read in wikipedia that sensitive toothpaste contains kno3. Lot of sensitive toothpaste can be found in my country. But, how to pure it?

You would need to look at the labels and see what else is there. My guess is that they don't contain a lot of KNO3 and that it might be difficult to extract.

Buying tubes and tubes of toothpaste would cost more than buying a bag of pure potassium nitrate!!

Yes, I know that, what I meant was, you'll never be able to purify it and get it out of the toothpaste because there's so much other crap ingredients in there!
