Instruction of Hydroxyethyl Cellulose

I. Product Overview

Hydroxyethyl Cellulose (abbreviated as HEC) is a non-ionic water-soluble cellulose, presenting as a white to pale-yellow, odorless, and free-flowing powder. Thanks to its excellent properties such as thickening, suspending, binding, emulsifying, film-forming, and water retention, it is widely used in numerous fields.

II. Physical and Chemical Properties

- **Solubility**: It dissolves readily in both cold and hot water, forming clear and viscous solutions.

- **Density**: The relative density is approximately 1.34. This density characteristic affects its sedimentation and dispersion in formulations.

- **pH Value**: Its aqueous solution has a pH value in the range of 6.0 - 8.5, from neutral to slightly alkaline, making it compatible with various systems.

III. Product Advantages

- **Outstanding Thickening Effect**: Even with a low dosage, it can significantly increase the viscosity of aqueous systems, helping various products achieve ideal rheological properties, whether it is a thin emulsion or a thick paste.

- **High Stability**: It shows good resistance to heat, acids, alkalis, and microorganisms, ensuring that products containing hydroxyethyl cellulose maintain their original properties during long-term storage and complex processing procedures.

- **Excellent Water Retention**: It can firmly retain water. In fields such as cosmetics and architectural coatings, it prevents water from evaporating too quickly, extending the service life and the duration of the effect of the products.

IV. Application Areas

- **Construction Industry**

- **Cosmetics Industry**

- **Food Industry**

V. Usage Instructions

It is recommended to slowly sprinkle hydroxyethyl cellulose into the stirred cold water first. Keep stirring until the particles are fully dispersed and swollen. Then, heat the solution as required to accelerate dissolution. Throughout the process, avoid agglomeration. Only the homogeneous solution can be put into use.

VI. Precautions

- **Storage Conditions**: Store it in a cool, dry, and well-ventilated warehouse, away from heat sources and open flames, and keep it separated from strong oxidizing agents to prevent chemical reactions.

- **Protective Measures**: During operation, workers should wear dust masks, protective goggles, impermeable work clothes, and rubber gloves. In case of contact with dust, immediately rinse with plenty of clean water. If it accidentally gets into the eyes, seek medical attention promptly after rinsing.
