At low concentrations, HEC solutions exhibit Newtonian behavior, characterized by a constant viscosity regardless of shear rate. However, as concentration increases, the solutions transition to non-Newtonian behavior, and the viscosity becomes dependent on the shear rate applied. This behavior is particularly beneficial in applications that require modifications of flow properties under different processing conditions such as mixing, pumping, and application.

In the pharmaceutical sector, Ashland’s HEC plays a critical role in the formulation of controlled-release medications. Due to its biocompatibility and ability to form hydrogels, HEC serves as an excipient that can modulate drug release profiles, ensuring that active ingredients are delivered effectively over time. This property is increasingly valuable in developing targeted therapies, leading to enhanced patient compliance and therapeutic outcomes.
