Secondly, the physical entanglement of polymer chains plays a significant role in the thickening action of HEC. As HEC is added to water, the polymer chains become flexible and coil within the solution. The chains can become entangled with one another, creating a network that inhibits the movement of the liquid. This entangled network effectively traps water within its structure, which results in an increase in resistance to shear stress and therefore enhances the viscosity of the mixture. This characteristic is especially useful in products that must remain stable and homogeneous over time.

Hydroxyethyl cellulose prices can also vary by region. For instance, areas with a strong manufacturing base for HEC, such as North America, Europe, and parts of Asia, may have more stable pricing due to established supply chains.
