    One of the primary differences between HPMC and methylcellulose is their molecular weight. HPMC has a higher molecular weight than methylcellulose, which means it can form more extensive and stronger gels. Therefore, HPMC is often used in applications where high viscosity and gel strength are required, such as in pharmaceutical tablet coatings and sustained-release formulations.

    In the pharmaceutical industry, HEC powder is commonly used as a thickening agent in liquid formulations such as syrups, suspensions, and ointments. Its ability to increase the viscosity of liquid formulations helps to improve the stability and consistency of the product. HEC powder is also used as a binder in tablet formulations to improve the cohesion and disintegration of the tablet.
