  • In conclusion, hydroxyethyl cellulose, identified by its CAS number 9004-62-0, is a multifaceted chemical compound with a broad range of applications across several industries. Its unique properties, derived from its cellulose origin and chemical modification, have made it a valuable tool in formulating products that require specific rheological and stabilizing characteristics. As research and development continue, the potential uses of HEC are likely to expand even further, solidifying its position as a key player in modern industrial chemistry.
  • China's Redispersible Polymer Powder A Key Ingredient in Modern Construction Materials

  • Appearance: both HPMC and HEC are white powder. HPMC is a Non-ionic compound, a non-reactive viscoelastic polymer. HEC raw material is Alkaline Cellulose and Ethylene Oxide.

  • Thickening:

  • However, the industry faces challenges, including fluctuating raw material prices, increasing competition, and the need for continuous technological advancements. Despite these, China's redispersible powder market continues to expand, driven by the country's rapid urbanization, infrastructure development, and rising demand for high-quality construction materials.
  • Moreover, the role of HPMC dispersion extends beyond its physical attributes. Its hydrophilic nature aids in moisture control, while its non-toxicity makes it suitable for food and pharmaceutical applications. It also exhibits excellent film-forming capabilities, making it a popular choice in coatings and paints.
  • Another reason why HPMC is deemed safe is that it is easily eliminated from the body
  • The 'HPMC%' you might encounter refers to the percentage concentration of HPMC in a particular product. This percentage can vary depending on the intended application and desired effects. Higher percentages typically result in thicker consistency or slower drug release.
  • Lastly, market competition and the presence of key players also shape HEC prices. Large manufacturers often have a pricing advantage due to economies of scale, while smaller players may need to adjust their prices to maintain competitiveness.
  • One of the most common uses of HPMC is in the construction industry, where it is used as an additive in cement-based products. When added to cement, HPMC acts as a thickening agent and improves workability, adhesion, and water retention. This makes it an essential ingredient in mortar, tile adhesives, grouts, and other building materials.
  • In addition to its use as an enteric coating agent, HPMCP powder also functions as a binder, matrix former, and film former in tablets and capsules. Its excellent flow properties and compatibility with a wide range of active ingredients further enhance its versatility in formulation design.
  • Hydroxyethyl cellulose (HEC), a derivative of the naturally occurring cellulose, is a water-soluble polymer that has found extensive use across various industries due to its unique properties and versatility. The compound, with a chemical formula (C6H14O5)n(C2H5OH)2, is formed by the reaction of cellulose with ethylene oxide, resulting in hydroxyethyl groups attached to the cellulose backbone.
  • The viscosity of a solution containing HEC is dependent on several factors, including the concentration of HEC, the molecular weight of the polymer chains, and the temperature of the solution. Higher concentrations of HEC and longer polymer chains typically result in a thicker solution

  • HPMC's HS code varies depending on its specific properties, such as viscosity,（degree of substitution), and the application it is intended for. Generally, HPMC falls under the HS code 391239, which covers Cellulosic ethers, whether or not chemically modified, in primary forms. However, it is essential to note that this can differ based on the country or region's customs regulations.

  • Cellulose is the most frequent polysaccharide in nature consisting of (some hundreds up to ten thousands) β-glycosidic linked glucose molecules. It is the main constituent of plant cell walls and vegetable fibre. It occurs mostly associated with hemicelluloses and lignin. It is therefore a common component of plant-based feed for all food producing and companion animals. However, these animals are not capable to digest cellulose enzymatically due to the lack of cellulases. The monomer element of cellulose, glucose, will not be released from cellulose. But gastrointestinal microbes can split cellulose, the main degradation products are short-chain fatty acids. In a simplified view, monogastric animals cannot digest cellulose, small amounts are microbially degraded in the large intestine. Minor amounts of cellulose may be absorbed as such by paracellular transport (passing through the intercellular space) or by transcytosis (transcellular transport of macromolecules captured in vesicles). On the other side, animals with large fermentation chambers in the intestine, such as ruminants, horses and rabbits, utilise large amounts of cellulose as energy source. In summary, cellulose is a natural part of feed and plays a physiological role in nutrition of animals (see Section 3.2.1).
