uses of hydroxypropyl methylcellulose.
- At the molecular level, HPMC consists of a cellulose backbone with hydroxypropyl and methoxy groups attached as substituents. These substitutions disrupt the hydrogen bonding between cellulose chains, reducing the crystallinity of the material. As a result, HPMC does not form the strong interchain associations typical of native cellulose, making it more susceptible to solvation by water molecules.
