Additionally, the COVID-19 pandemic has had an impact on the HPMC market, leading to supply chain disruptions and fluctuating demand levels. These factors have further contributed to the price volatility of HPMC.

For industrial applications, consider purchasing hydroxyethyl cellulose from specialty chemical suppliers. Companies like Dow Chemical, Ashland, and BASF are well-known for their extensive ranges of polymer products, including HEC. These suppliers often offer bulk purchasing options and can provide additional services such as custom formulations, technical support, and logistics.



HPMC is produced by the chemical modification of cellulose, a polymer obtained from wood pulp or cotton linters. The process involves etherification, where cellulose is reacted with propylene oxide and methyl chloride. This chemical process imparts hydrophilic properties to cellulose, enabling it to dissolve in water and form viscous solutions. The viscosity and functional properties of HPMC can be adjusted by controlling the degree of substitution of the hydroxypropyl and methyl groups during production. As a result, manufacturers can produce a tailored product that meets specific requirements for various applications.


This plant-derived cellulose has been an option for vegetarian capsules in pharmaceutical applications since 1998. It is a physically stable polymer that’s resistant to stringent heat and humidity conditions, with a low moisture content that makes it suitable for moisture-sensitive ingredients. The role of the HPMC capsule is to protect its contents from degradation or product changes, which means insulating against temperature fluctuations or moisture exposure, the stability of the capsule material is a critical factor in product development.

What is HPMC?


The structural characteristics of hydroxyethyl cellulose play a key role in defining its physicochemical properties and diverse applications. As a natural polymer modified to enhance its functionalities, HEC has established itself as an essential ingredient across multiple sectors. Its versatility, combined with an increasing focus on sustainable and safe materials, will likely continue to drive innovation and expand its usage in the future. As research advances, new formulations and applications of this valuable compound will undoubtedly emerge, reinforcing the relevance of hydroxyethyl cellulose in modern industries.


In addition to enhancing workability, HPMC also serves as a good binder in construction materials. It helps the different components of a mix stick together, preventing segregation and improving the strength of the final product. This makes it an essential ingredient in tile adhesives, cement renders, and gypsum-based plasters, among others.

The production of redispersible polymer powders typically involves emulsion polymerization, wherein various monomers are polymerized in an aqueous dispersion. The resulting polymer particles are then dried using methods such as spray drying or freeze drying. These processes help to form a powder that retains the properties of the emulsion—primarily the ability to be redispersed in water and to reform the original polymer film upon curing.


In addition to these three main types, there are also specialized grades of HPMC with unique properties and applications. For example, HPMC with a delayed hydration profile is designed to delay the hydration and dissolution of the polymer in aqueous solutions. This allows for a more controlled release of the active ingredient, making it ideal for modified-release formulations. Furthermore, HPMC with enhanced thermal stability is specifically formulated for use in high-temperature processing methods such as hot melt extrusion. Hydroxyethylcellulose is also employed in the construction industry as an additive in mortars, tile adhesives, and other building materials. Its role as a thickener enhances the workability of these products, making them easier to apply. Moreover, it improves water retention, which is crucial for ensuring proper curing and adhesion in construction applications.
