Products Description
The substance with CAS number 9004 - 62 - 0 is Hydroxyethyl Cellulose, referred to as HEC, with a molecular formula of (C₂H₆O₂)ₙ.
Hydroxyethyl Cellulose is a white or light-yellow fibrous or powdery solid, odorless, with a melting point of 288 - 290 ℃ and a density of 0.75 g/cm³ (25 ℃). It is easily soluble in water and insoluble in general organic solvents. It is unstable at room temperature and pressure and should be protected from moisture, heat, and high temperature. It has good salt solubility in electrolytes, and its aqueous solution can contain high concentrations of salts without changing. The viscosity changes little within the pH range of 2 - 12, but the viscosity decreases beyond this range.

Safety Information
It is less irritating to the skin, but it is still necessary to avoid long-term contact or accidental ingestion.
When storing, it should be placed in a dry, cool, well-ventilated place to avoid direct sunlight and high temperature.
Uses
Oil extraction: Hydroxyethyl Cellulose is used as a thickener and fluid loss reducer. It has a significant thickening effect in salt water drilling fluids and can also be used as a fluid loss reducer for oil well cement.
Paint: As an emulsifying thickener, it improves the viscosity and stability of paint.
Construction: As a cement retarder and moisture retainer, it is used to improve the performance of building materials.
Medicine and food: In the pharmaceutical field, it can be used as a lubricant, such as an additive to eye drops to promote the moistening and lubrication of the eyeball; in the food field, it can be used as a stabilizer.
Textile: As a sizing agent, it improves the quality and performance of textiles.
Papermaking: Used to improve the strength and uniformity of paper.
