4. Mix Thoroughly Continue stirring for several minutes. If you are using a high-shear mixer or blender, this process may take less time. The mixture will start to thicken as the HEC absorbs water.
The viscosity of HPMC plays a crucial role in determining the performance of the end product. For instance, in the pharmaceutical industry, the viscosity of HPMC can influence drug release rates from hydrophilic matrices and impact the stability of suspensions. In food applications, the viscosity contributes to the mouthfeel and texture of sauces and dressings. In construction, appropriate viscosity ensures that mortar and adhesive formulations maintain their application properties while setting.
High viscosity grade HPMC is primarily employed in food applications as a thickener and stabilizer. It imparts a smooth and creamy texture to dairy products, sauces, and dressings while also preventing phase separation and syneresis. The high viscosity grade is essential for creating stable emulsions and suspensions in food formulations.
Hydroxypropyl methylcellulose, commonly known as HPMC, is a cellulose-based polymer that has found widespread applications across various industries.

Conclusion
HEC is increasingly utilized in construction materials, particularly in the formulation of mortars, adhesives, and paints. It acts as a water-retention agent, enhancing workability while preventing rapid drying that can lead to cracking. These properties are especially beneficial in tile adhesives and cement-based products, where consistent application and long-term durability are essential. Additionally, HEC enhances the ease of application and improves the adhesion of coatings, making it a crucial component in the construction industry.
One of the most significant features of hydroxyalkyl cellulose is its ability to form hydrophilic gels and films, which has led to its widespread use in the pharmaceutical, cosmetic, and food industries. In pharmaceuticals, HAC serves as a critical excipient in drug formulations, particularly in the development of controlled-release systems. Its gel-forming properties help in sustaining the release of active pharmaceutical ingredients, ensuring a prolonged therapeutic effect and improved bioavailability.
The first patent of the capsule which is for replacing the gelatin-based capsule in the market was filed in 1950 by HW Murphy of Eli Lilly and Company. There were many problems with the early HPMC, and Taizo Yamamoto, Kenji Abe, and Seinosuke Matsuura et al Qualicaps Co Ltd proposed improvement project (US Pat. Nos. 5,264,223 and 5,431,917). Then the project is further improved by Suheung Capsule Co., Ltd., Warner-Lambert Company, etc. The first trademark Vegicaps was registered by G S Technologies Inc. (now owned by R.P. Scherer Technologies) in 1989. Compared to gelatin capsules, HPMC capsule is with a higher price due to its more complex process and more expensive raw materials.
Hydroxypropyl methylcellulose (HPMC) is a non-ionic, water-soluble polymer widely recognized for its versatile properties and applications across various industries. Developed from cellulose, a natural polymer derived from plants, HPMC is synthesized by substituting hydroxyl groups in the cellulose structure with hydroxypropyl and methyl groups. This modification results in a compound that exhibits unique features, making it an essential ingredient in pharmaceuticals, food products, construction materials, and cosmetics.
Pharmaceutical applications of HEC are equally noteworthy; it serves as a controlled-release agent in the formulation of tablets and ointments. Its ability to form a viscous gel when hydrated aids in the sustained release of active ingredients, thereby improving therapeutic efficacy.
