Before beginning the dissolution process, it is essential to determine the desired concentration of HEC for your application. Commonly, HEC is dissolved in concentrations ranging from 0.5% to 2.0%. Keep in mind that higher concentrations may require more effort and time to dissolve completely.

2. Pharmaceuticals In the pharmaceutical sector, HPMC plays a crucial role as a binder, coating agent, and controlled-release agent. It is commonly found in tablet formulations and as an excipient in controlled-release medications, ensuring the gradual release of active ingredients into the body. HPMC's biocompatibility makes it ideal for use in drug delivery systems, where it helps in enhancing the solubility and stability of drugs.

3. Moisture Content HPMC is hygroscopic, meaning it can absorb moisture from the environment. This absorption can lead to variations in density, especially when HPMC is stored in humid conditions. The presence of water can cause swelling of the polymer, thus changing the volume and density.
