  • HPMC Manufacturers in China


  • According to the SDS, Hydroxyethyl Cellulose is generally considered to be non-toxic and non-hazardous under normal handling conditions. However, it is vital to recognize potential hazards. Dust generated during the handling or processing of HEC can pose respiratory risks if inhaled in significant quantities. As a precaution, it is recommended to minimize dust generation and exposure, particularly in poorly ventilated areas.


  • What is Gelation Temperature?


  • The construction industry has also benefited from the unique properties of HPMC. It is commonly used in the formulation of cement-based dry-mix products, such as tile adhesives and joint compounds. HPMC improves workability, water retention, and adhesion of these materials, making application easier while ensuring durability and performance. Moreover, its water-retaining properties are critical, as they allow for better curing of cement, which ultimately enhances the strength of the final structure.

  • 2. Alkali Treatment The purified cellulose is treated with an alkali solution (often sodium hydroxide) to create alkali cellulose. This treatment enables the cellulose fibers to swell and facilitates the subsequent chemical modifications.

  • In addition, vinyl acetate ethylene redispersible powder contributes to the water retention and setting properties of tile adhesives and mortars. By forming a protective film around the cement particles, this redispersible powder helps to slow down the drying process, allowing for better hydration and stronger adhesion to the substrate. This is particularly important in areas with high humidity or temperature fluctuations, where rapid drying can affect the overall quality and performance of the construction material.

  • 1. Choosing the Right Concentration


  • Moreover, HPMC grades also play a vital role in cosmetic formulations, where the consistency and stability of creams and lotions are paramount. The ability of HPMC to form a film on the skin enhances product performance, providing a smooth application and enhancing moisture retention. Different grades contribute to the rheological properties of cosmetic products, enabling formulators to achieve the desired viscosity and texture.


  • What is HPMC?


  • Allergic reactions to HPMC are rare but possible. Some people may experience skin irritations, rashes, or respiratory issues after exposure or ingestion of products containing HPMC. It is crucial for individuals with known allergies to cellulose derivatives or similar compounds to approach HPMC consumption with caution. If any allergic symptoms occur, such as hives, difficulty breathing, or swelling of the face and throat, immediate medical attention should be sought.

  • 3. Water Retention The compound’s ability to retain water enhances the quality of products such as mortars, plasters, and other construction materials. This property helps maintain moisture levels, leading to improved workability and durability.


  • MHEC also possesses unique rheological properties, which are pivotal in controlling the flow behavior of materials. It provides pseudoplastic behavior, meaning that its viscosity decreases under shear stress. This feature is highly desirable in formulations where easy application and manipulation are required, such as in coatings, adhesives, and sealants.


  • Personal Care and Cosmetics


  • China is a leading supplier of methyl hydroxyethyl cellulose (MHEC), a versatile chemical compound that is used in a wide range of industries. MHEC is a type of cellulose ether that is derived from natural cellulose and is modified to have improved properties for various applications.
  • An aqueous solution of HEC is a non-Newtonian fluid, and its viscosity changes as the shear rate changes.
    The viscosity increases as the shear rate decreases, while the viscosity decreases as the shear rate increases (thixotropy).
    The thixotropy of an aqueous solution of HEC increases with higher viscosity products with higher molecular weight, and decreases with lower viscosity products. Low-viscosity products have very low thixotropy and exhibit characteristics similar to Newtonian fluids.
