When HEC is added to water, its long polymer chains begin to interact with the water, creating a thickening effect. The chains of HEC become entangled and form a semi-solid network in the water phase. This network disrupts the flow of the liquid, resulting in increased viscosity. The thickening is primarily a result of the physical entanglement of the polymer chains rather than any chemical reaction, which differentiates HEC from many other thickening agents that may rely on gelling or coagulating processes.
