Conclusion

Hydroxypropyl methylcellulose (HPMC) has emerged as a versatile excipient in the pharmaceutical industry, particularly renowned for its role in the formulation of various drug delivery systems. One of the critical physical properties influencing the stability and efficacy of HPMC-based formulations is its glass transition temperature (Tg). The glass transition temperature is a pivotal phenomenon that characterizes the transition between the glassy and rubbery states of amorphous materials, such as polymers.

- Pharmaceuticals The pharmaceutical sector also relies on silicone defoaming agents to maintain production efficiency and product quality in liquid formulations.

3. Food Industry Cellulose ethers also find applications in the food sector, where they act as thickening agents, stabilizers, and emulsifiers. They help improve the texture and viscosity of sauces, dressings, and dairy products, making them essential for various food formulations.
