Abstract
A method for inhibiting deposition of multivalent saturated fatty acids on paper sizing equipment and/or devices which use a paper surface sizing composition containing one or more surface sizing starches and a source of multivalent cations, such as a multivalent metal drying salt, by including a C16 or higher saturated fatty acid solubilizing and dispersing surfactant in the paper surface sizing composition. Also, a paper surface sizing system for carrying out this method.
