wow! okay that exactly what i was looking for. first off testrasodium phosphate doesn't sound like anything i want in my body. but then again the highest grade stuff is made with "tin stabilizers" i mean do i want to put tin in my body? i wonder if its just trace amounts, like 10 ppm or something. so obviously its either 35% or nothing at all, but still that tin thing worries me. thanks for the great research though, i couldn't find anything on this.
