Abstract
A stable, fluid alkaline earth metal tallate dispersion is prepared by (i) forming a pre-emulsion of fatty acids derived from tall oil, water, and a surfactant; (ii) forming an alkaline earth metal salt dispersion from an alkaline earth metal oxide and/or hydroxide, a lower carboxylic acid, and water; and (iii) incorporating the pre-emulsion into the alkaline earth metal salt dispersion under high shear and low pressure.
