Before diving into the dissolution process, it's crucial to understand the properties of HPMC that influence its solubility. HPMC is often available in different grades, characterized by varying viscosity and substitution levels. The degree of substitution affects how it interacts with water. Generally, HPMC is soluble in cold or warm water and creates a gel-like solution once fully hydrated.
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.
