- The chemical structure of HPMC imparts it with unique properties that make it suitable for diverse applications. Its water solubility allows it to be used as a thickening agent, a stabilizer, and a film-former in different formulations. In pharmaceuticals, HPMC is employed as a binder in tablet manufacturing, a coating material for capsules, and a suspending agent in liquid medications due to its ability to control drug release rates.
- In the pharmaceutical industry, HPMC is primarily used as a thickening agent, film former, and sustained-release coating material. As a thickener, it increases the viscosity of liquids without altering their taste or color, making it ideal for oral suspensions, syrups, and emulsions. Its film-forming property allows it to create protective coatings on tablets and capsules, enhancing their appearance and stability. Moreover, HPMC's ability to control drug release makes it an essential component in controlled-release formulations, allowing for precise and prolonged drug delivery.
- In the construction industry, HEC serves as a thickener and stabilizer in cementitious materials, enhancing their workability and reducing water demand. It also improves the durability and crack resistance of concrete, making it an essential ingredient in modern construction practices. In paint and coatings, HEC acts as a suspending agent, preventing pigments from settling and providing a smooth finish.
- Furthermore, HPMC finds applications in the food industry as a stabilizer, emulsifier, and thickening agent. It is used in products like ice cream, jams, and bakery goods, improving texture and shelf life.
- According to market research, the redispersible polymer powder market share is expected to witness significant growth due to the increasing demand for sustainable and eco-friendly building materials. These polymers, derived mainly from vinyl acetate-ethylene (VAE) copolymers, offer superior properties like water resistance, adhesion, and flexibility, making them ideal for modern construction needs.


In the UK it was submitted by Dow (who manufacture HPMC for the global food market) for approval to the Advisory Committee on Novel Foods and Processes in November 2011.
I haven’t found a single loaf of bread, roll or sandwich thin that doesn’t now contain this additive.
7. Hydroxypropyl Methylcellulose has better enzyme resistance than MC, and the possibility of enzymatic degradation of Hydroxypropyl Methylcellulose is less than that of MC.


DS: the substituent of HPMC is Hydroxypropyl and Methoxy. The ratio of them affects HPMC properties. The higher the hydroxypropyl content, the better the water retention effect. The lower the methoxy content, the higher the gel temperature. The DS of HPMC is 1.2-2.0. But HEC substituent is Hydroxyethyl substituent. Its DS is 1.5-2.0.
