The pH value changes slightly in the viscosity range of 2-12, but the viscosity decreases beyond this range. It has properties such as thickening, suspension, adhesion, emulsification, dispersion, moisture retention, and protective colloid. Can prepare solutions with different viscosity ranges. It is unstable at room temperature and pressure, avoiding humidity, heat, and high temperatures. It has exceptional salt solubility to the dielectric, and its aqueous solution allows for high concentrations of salts to remain stable.
