Hydroxyethyl Cellulose

Character

White to light yellow fibrous or powdery solid, non-toxic, tasteless, easily soluble in water. Insoluble in general organic solvents. The PH value is within the range of 2-12 and the viscosity changes little, but beyond this range the viscosity decreases. It has properties of thickening, suspension, adhesion, emulsification, dispersion, moisture retention and colloid protection. Solutions with different viscosity ranges can be prepared. It is unstable under normal temperature and pressure, avoiding humidity, heat and high temperature, and has unusually good salt solubility for the dielectric. Its aqueous solution can contain high concentration of salt and remain stable.

Application

Used as adhesive, surfactant, colloid protectant, dispersant, emulsifier and dispersing stabilizer etc. It is widely used in coating, ink, fiber, dyeing, papermaking, cosmetics, pesticide, mineral processing, oil extraction and medicine.
