  • Generally, HPMC with a higher DS and a lower molecular weight tends to be more soluble in ethanol. This is because the higher degree of substitution introduces more polar groups along the polymer chain, increasing its affinity for ethanol This is because the higher degree of substitution introduces more polar groups along the polymer chain, increasing its affinity for ethanol This is because the higher degree of substitution introduces more polar groups along the polymer chain, increasing its affinity for ethanol This is because the higher degree of substitution introduces more polar groups along the polymer chain, increasing its affinity for ethanolhpmc solubility in ethanol. Similarly, a lower molecular weight allows the polymer chains to pack more loosely, making it easier for them to interact with the solvent molecules.
  • HPMC, short for hydroxypropyl methylcellulose, is another type of cellulose ether that is commonly used in the pharmaceutical and construction industries. Like Hec, HPMC is also soluble in water and forms a clear, colorless solution. HPMC is often used as a thickener, binder, film former, and coating agent in pharmaceuticals, as well as a thickening agent, water retention agent, and workability improver in construction materials. It is known for its high compatibility with other ingredients and its ability to provide good adhesion and moisture resistance in various formulations
