  • HPMC, a modified form of cellulose, is a non-ionic, thermally stable, and water-soluble polymer. Its solubility in water is a key characteristic that makes it highly versatile. When HPMC is introduced to cold or hot water, it forms a clear, viscous solution. This property is largely dependent on the degree of substitution, molecular weight, and the temperature of the water.
  • Firstly, HPMC is known for its excellent water solubility. In, it forms a gel-like substance, which makes it suitable for applications in construction materials as a thickener or binder. Its ability to retain water also makes it a popular ingredient in the pharmaceutical industry, where it is used as a disintegrant in tablet formulations.
  • Another important factor to consider when choosing an HPMC grade is its degree of substitution (DS). DS refers to the number of hydroxyl groups on the cellulose molecule that have been substituted with hydroxypropyl groups. A higher DS means that more hydroxyl groups have been replaced, resulting in a more hydrophilic polymer. This property makes high-DS HPMC suitable for applications that require water-soluble films or coatings, such as in the pharmaceutical industry.
