MelaColl™ Hydroxyethyl cellulose (HEC) is a nonionic, water-soluble polymer. It consists of two components: cellulose and hydroxyethyl side chain.

MelaColl™ Hydroxyethyl Cellulose (HEC) is a versatile, nonionic, water-soluble polymer that plays a pivotal role in numerous applications thanks to its unique properties derived from its cellulose backbone and hydroxyethyl side chains. The manufacturing process involves several key steps, starting with cellulose purification, followed by alkalinization with sodium hydroxide to form swollen alkaline cellulose, and finally reacting with ethylene oxide to introduce hydroxyethyl groups. This process yields a product with a wide array of beneficial properties.

Properties of MelaColl™ HEC:

  • Water Retention: MelaColl™ HEC is highly efficient in retaining water, making it an essential additive in formulations that require moisture preservation, such as construction materials and personal care products.
  • Thickening: It acts as a thickener, providing the desired viscosity to a variety of products, from paints to beauty products, without altering other properties.
  • Suspension: Its ability to stabilize suspensions ensures that solid particles are evenly dispersed within a liquid, crucial for applications in paints, drilling fluids, and pharmaceuticals.
  • Anti-Microbial: MelaColl™ HEC inherently resists microbial growth, enhancing the shelf life and safety of products it is incorporated into.
  • High Salt Tolerance: It performs exceptionally well in high-salt environments, making it suitable for use in oil drilling fluids and other industrial applications where salt presence is significant.
  • Ion/PH Insensitivity: Its effectiveness is not compromised by variations in pH or the presence of ions, ensuring consistent performance across a broad range of formulations.






HE10000B (Viscosity: 10000-20000 mPa.s, 2% solution)

  • Application: Detergent
  • Properties: This grade offers good suspension capabilities with relatively low viscosity, making it ideal for liquid detergents and cleaning agents where moderate thickening is desired without compromising fluidity. It ensures that ingredients remain evenly distributed, enhancing the product's stability and performance.

HE20000B (Viscosity: 18000-28000 mPa.s, 2% solution)

  • Application: Detergent
  • Properties: Similar to HE10000B but with a higher viscosity range, HE20000B provides enhanced suspension properties. This makes it suitable for detergents that require a slightly thicker consistency, ensuring that active ingredients are effectively suspended and uniformly distributed throughout the product.

HE30000B (Viscosity: 25000-35000 mPa.s, 2% solution)

  • Application: Latex Paint
  • Properties: Featuring good suspension and excellent workability, this grade is tailored for the paint industry, particularly in latex-based paints. It aids in maintaining pigment suspension, preventing settling, and ensuring a smooth application. Its workability enhances the paint's ease of use, contributing to a uniform and appealing finish.

HE35000B (Viscosity: 30000-40000 mPa.s, 2% solution)

  • Application: Latex Paint
  • Properties: Offering similar benefits to HE30000B but with a higher viscosity, HE35000B also provides good suspension and excellent workability. This grade is ideal for latex paints that require a thicker consistency for better application control and a more durable finish.

HE40000B (Viscosity: 35000-45000 mPa.s, 2% solution)

  • Application: Detergent
  • Properties: This grade is designed for detergents needing good suspension capabilities but with a higher viscosity than the lower grades. It ensures that particles remain suspended, enhancing the cleaning efficacy and stability of the detergent formula.

HE50000B (Viscosity: 40000-50000 mPa.s, 2% solution)

  • Application: Detergent; Oil Drilling
  • Properties: The highest viscosity range in this series, HE50000B, is characterized by good suspension, high viscosity, and high temperature stability. In detergents, it provides excellent suspension of active ingredients and thickening necessary for optimal viscosity. For oil drilling applications, its high viscosity and temperature stability are crucial for maintaining the performance of drilling fluids under extreme conditions, stabilizing the fluid, and facilitating the suspension of drill cuttings.


Each grade of MelaColl™ Hydroxyethyl Cellulose (HEC) is engineered to meet the specific needs of its applications, from enhancing the performance and stability of detergents to improving the workability and finish quality of latex paints, and supporting the rigorous requirements of oil drilling operations. These properties underscore the versatility and effectiveness of HEC as a polymer additive across a range of industries.
