  • Patent number: 5906971
    Abstract: The present invention relates to a composition and process for stabilizing inorganic salts. The composition generally includes a carboxylated polymer that has been neutralized with an alphahydroxy amine. The composition can be used, for example, to disperse and suspend inorganic salts, such as silicates and sulfates, in fluids for inhibiting the insoluble inorganic matter from agglomerating and forming deposits on surfaces in contact with the fluid. The present invention is particularly suitable for use in industrial water handling systems such as boilers, coolers, and the like in other various industrial applications where inorganic salts form scale in a vessel in which an aqueous liquid is handled.
