Additionally, HPMC is commonly utilized in ophthalmic solutions due to its lubricating properties, which enhance comfort and hydration in eye care products.

3. Food Industry

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.

Hydroxyethyl cellulose is increasingly used in the construction industry, particularly in the formulation of dry mix products such as tile adhesives, plaster, and joint compounds. Its water-retention properties help maintain adequate moisture levels during the curing process, thereby enhancing the performance and durability of these materials.
