I believe the non-food grade is 3%. I will have to check.
The food grade is so potent - that a drop on your skin burns and turns it white.
I think when I asked several months ago - the one at our Health food store was 35%.
We've had it before - can't remember what my husband was using it for...but he had to dilute it...
What kind of garbage is in the non-food grade that is sold in pharmacies? Or, is it the same, they just can't call it food grade because they don't follow strict guidelines in the production of it.
