It does not contain any free phosphate (PO4 3-). The guaranteed
analysis lists less than 0.01% Phosphorous which comes from small
amounts of phosphate _esters_, not free phosphate. Anionic phosphate
esters are very hydrolytically stable (i.e. very slowly hydrolyzed by
water to free phosphate)... (incidentally, this is why DNA is so
stable). Because of this stability very little of that already small
<0.01% will ever hydrolyze to free phosphate.
