2. Medium Viscosity Grades With viscosities ranging from 3000 to 10000 mPas, these HPMC grades provide a balance between water retention and workability. They are often used in pharmaceutical formulations, such as tablets and capsules, due to their ability to control the release of active ingredients.

3. Supply and Demand The balance between supply and demand in the market plays a critical role in determining prices. For instance, an increase in construction activity can lead to higher demand for HPMC powder, consequently driving up prices. Conversely, economic downturns can reduce demand and lead to price drops.

HPMC is prized for its unique characteristics. In the pharmaceutical industry, it acts as a thickener, binder, and controlled-release agent in various formulations. For the food industry, it serves as a stabilizer, emulsifier, and texturizing agent, enhancing the mouthfeel and overall quality of food products. In construction, HPMC is commonly used in mortars and adhesives due to its water-retention capabilities, which improve workability and extend the open time of products. Furthermore, its application in personal care products and cosmetics such as shampoos and lotions highlights its versatility.

1. Pharmaceuticals In the pharmaceutical industry, high viscosity HPMC plays a pivotal role as a binder, thickener, and film-forming agent in various dosage forms, including tablets, capsules, and suspensions. Its ability to provide controlled release of active ingredients makes it invaluable in formulating extended-release medications. Additionally, its compatibility with various excipients aids in achieving an optimal consistency and stability in medicinal products.

A key characteristic of HPMC is its ability to form a gel in aqueous solutions, making it an effective thickening and binding agent. It is non-ionic, which means it doesn't carry a charge in solution, facilitating its use in a variety of formulations without causing ionic interference. Furthermore, HPMC has excellent film-forming capabilities, contributing to its widespread application in different fields.

Used as adhesive and sizing agent in fabric printing and dyeing slurries and latex paints; used as thickener for sizing materials on the back of carpets. Used as molding agent and binder in glass fiber; used as modifier and binder in leather pulp. Providing these coatings or adhesives with a wider viscosity range allows the coating to settle more evenly and quickly, and improves print clarity.

The solubility of HPMC in cold water makes it ideal for numerous applications. In the pharmaceutical industry, it is commonly used in drug formulations as a binder, coating agent, and thickener. Its ability to form gels and controlled-release mechanisms is particularly valuable in developing sustained-release dosage forms.

1. Pharmaceutical Grades In the pharmaceutical industry, HPMC is often used as an excipient in tablet formulations. It acts as a binder, controlling the release of active ingredients. For instance, low viscosity HPMC grades are used in immediate-release formulations, while high viscosity grades are utilized for controlled-release applications.

Understanding Hydroxyethyl Cellulose (HEC) and Its Applications
