ABSTRACT:
Improved potassium sulfate salt products in both solid particulate and liquid form are provided which exhibit enhanced salt solubility in water. The products include potassium sulfate, in combination with a surfactant and mixed together in water. The aqueous mixture is heated to a maximum reaction temperature in the range of about 100.degree.-210.degree. F., and will retain enhanced water solubility in either a heated or cooled condition. In preferred forms, potassium sulfate may be treated with at least 0.1% by weight of disulfonate surfactant and heated in water to 100.degree.-140.degree. F. to give K.sub.2 SO.sub.4 solutions of at least 8% by weight solubility taken as K.sub.2 O.
