- Geographically, the Asia Pacific region dominates the redispersible polymer powder market, attributed to the region's massive construction boom and rising disposable income levels
- Hydroxyethyl cellulose, also known as HEC, is a non-ionic water-soluble polymer that is derived from cellulose. It is commonly used in a variety of industries for its thickening, suspending, emulsifying, and film-forming properties.
- Temperature is another influential factor
- Beyond water, HEC exhibits limited solubility in organic solvents, preferring polar and protic solvents such as alcohols and acetone. Its solubility in these solvents is often enhanced when combined with water, forming a hydrogel.
- In terms of viscosity, HEC generally provides a higher viscosity at lower concentrations than HPMC, which can be advantageous in applications where a thicker consistency is desired
- Hydroxyethyl cellulose (HEC) is a versatile polymer that is widely used in various industries for its unique properties and applications. It is a non-ionic, water-soluble polymer derived from cellulose, which is a natural polymer found in plant cell walls. HEC is produced by reacting cellulose with ethylene oxide to introduce hydroxyethyl groups onto the cellulose backbone, hence the name hydroxyethyl cellulose.
- Moreover, redispersible polymer powder offers significant improvements in workability and water retention
- One of the primary domains where HPMC shines is in the pharmaceutical industry. Its ability to form viscous solutions upon dissolution in water makes it an ideal excipient for tablets and capsules. As a tablet binder, HPMC ensures uniform distribution of medication, improves the release profile of drugs, and enhances the overall manufacturing process. Additionally, HPMC is utilized as a thickener, emulsifier, and stabilizer in topical formulations such as creams and ointments.
- Hydroxypropyl Methylcellulose (HPMC) is a versatile and widely used polymer in the pharmaceutical industry. It is primarily utilized as a binder, disintegrant, and film-forming agent in the production of tablets.
The FEEDAP Panel agrees with the approach of the ANS Panel that, although the data set available for the different celluloses is not complete and most of the studies were old and do not meet the current requirements of toxicological testing, the physico-chemical, structural, biological and kinetic similarities between the modified celluloses make it possible to apply a read-across approach among the different celluloses. Overall, the available information allows to conclude that the celluloses (as a group) are of low toxicological concern.
- In the pharmaceutical industry, HPMC powder is used as a binder, thickener, and film-former in tablets, capsules, and ointments. The price of HPMC powder in this industry is influenced by factors such as the grade of the material and the quantity purchased. Pharmaceutical companies must ensure that they are using high-quality HPMC powder to meet regulatory standards and provide effective products to their customers.

In the food sector, HPMC serves as a stabilizer, emulsifier, and thickener, finding use in products like ice cream, jams, and sauces.
- On the other hand, HEC has a higher degree of hydroxyethyl substitution, which gives it better thickening and gelling properties. This makes HEC a popular choice for use in adhesives, coatings, and personal care products where a thicker consistency is desired.
- Construction HPMC or hydroxypropyl methylcellulose is a cellulose ether widely used in the construction industry. It is a key ingredient in many construction materials due to its ability to improve the performance and durability of the final product. In this article, we will explore the various applications of construction HPMC and its benefits.
- The solubility of HPMC increases with temperature. At lower temperatures, the polymer chains are more tightly packed, which makes it harder for water molecules to penetrate and solubilize the polymer. As the temperature increases, the polymer chains become more flexible, allowing water molecules to interact with the polymer more easily, leading to increased solubility.
