The kinematic viscosity and density of binary aqueous solutions containing xanthan gum and ternary aqueous solutions containing carboxymethyl cellulose and sodium chloride have been measured from 303 K to 318 K at different values of pH. The viscosity and density for binary and ternary systems showed increases with a higher concentration of hydrocolloids (xanthan gum or carboxymethyl cellulose) and reductions with increasing temperature. The presence of NaCl in the ternary systems produced an electro-viscous effect that influenced the viscosity and density of the system. The models used to predict the viscosity, density, and apparent specific volume demonstrated satisfactory results in comparisons with experimental data.
