Summary Slurries containing synthetic detergents, silicates, phosphates, and sometimes other additives, were prepared and their viscosities measured at several stresses. Portions of the mixtures were oven‐dried and dilute solutions prepared. Their turbidities and pH values were determined. Mixtures of silicate with pyrophosphate yielded lower viscosities and turbidities than with tripolyphosphate. A mixture of the two phosphates with silicate resulted in a still lower viscosity, but an intermediate turbidity. Increasing the alkalinity of the silicate decreased the turbidity, but the minimum viscosity occurred at an intermediate silicate ratio in most cases. A number of the additives tested lowered the viscosity, but all lowered the turbidity.
