ABSTRACT:
There is disclosed a caking inhibitor for mono-and diammonium phosphates which is water soluble and effective at small concentrations rendering the phosphates acceptable in most utilities without separation of the inhibitor. The inhibitor is sodium sulfate. Effective amounts of this salt range from about 0.5 percent to about 1 percent by weight in the ammonium phosphates. It is particularly advantageous that this salt is useful in both types of ammonium phosphates.
