The effects of various types of surfactants and inorganic phosphates upon the apparent viscosities of pigment‐water (50/50) suspensions are examined. The additions of surfactants or inorganic phosphates to the pigment‐water suspensions depress the apparent viscosities from the values of more than 10,000 centipoise to those of ca. 10 centipoise. The concentration of surfactants or inorganic phosphates required to depress the apparent viscosity depends upon the chemical composition and the mol wt of surfactants or inorganic phosphates. The effects are correlated with zeta potential, adsorption, and pH data.
