Changes in the Viscosity of Solutions of Sodium Carboxymethylcellulose and Methylcellulose Containing Acid Constituents

Abstract

Effect of storage conditions was investigated on the viscosity of 20g/l solutions of sodium carboxymethylcellulose and methylcellulose which showed non-Newtonian flow properties. The decrease of their viscosity during storage was accelerated by raising temperature and citric acid concentration, respectively, and by exposure to light.
