Merck：4673
Appearance: white to light yellow fibrous or powdery solid, non-toxic, tasteless, soluble in water. Insoluble in general organic solvents.
The PH value changes slightly in the range of 2-12, but the viscosity decreases beyond this range. It has the properties of thickening, suspension, adhesion, emulsification, dispersion, moisture retention and colloid protection. It can prepare solutions with different viscosity ranges. It is unstable under normal temperature and pressure, avoiding humidity, heat and high temperature. It has extremely good salt solubility to the dielectric. Its aqueous solution is allowed to contain high concentration of salt and remains stable.
