Abstract
Surface treated inorganic oxide pigments are provided wherein one or more of the ethylene glycol esters and diesters are applied to the surface of a base inorganic oxide pigment, for example, an anatase titanium dioxide pigment from the calciner of a conventional sulfate route process for making titanium dioxide pigments or especially a rutile titanium dioxide pigment from the oxidizer in a conventional chloride route process for making titanium dioxide pigments.
