Stable aqueous dispersions of organo-soluble multivalent ion salts of sulfonate group-containing compounds can be prepared in the presence of surface-active water-soluble alkyl hydroxyalkyl polysaccharides. These aqueous dispersions unexpectedly achieve high levels of storage stability at organo-soluble multivalent ion, sulfonate group-containing salt concentrations of up to 65% or greater, by weight based on total dispersion. The dispersions impart hydrophobic characteristics to the surfaces of materials onto which they are applied, are stable to storage, are compatible with a variety of other aqueous systems when blended therewith, and are useful as coatings designed for metal surfaces or as components of coatings designed for metal surfaces.
