Kirk,
Didn't you mean 'there is no reason to purify it so that it's not (IN)active.'
Sorry Kirk, i think i get it now, it getting late in the day for me.

Ummmm - let's see, I think there were too many negatives in my statement to make it understandable... Let's try again -

"If it's made for food use, there is no reason to purify it so that it's inactive."

I hope that is better -

Anyway, just what PE said. (Plus he beat me to that post by 1 minute and with much more clear language.)
