- HPMC is commonly used in the preparation of controlled release formulations, where it acts as a gelling agent to control the release rate of drugs. By adjusting the molecular weight and concentration of HPMC, manufacturers can tailor the gelation temperature to achieve the desired drug release profile.

hydroxy methyl cellulose. It also acts as a retarder, slowing down the setting time of cement, providing more flexibility during construction.
- HPMC, or Hydroxypropyl Methylcellulose, is a widely used chemical compound with the specific grade HPMC 4000 playing a pivotal role in various industries. It is a non-ionic, water-soluble cellulose ether derived from natural cellulose through chemical modification. The 4000 in HPMC 4000 refers to its viscosity rating, which is a key characteristic determining its application and performance.
- Spray drying, for instance, is a popular method for producing redispersible powders because it allows for precise control over particle size and morphology
redispersible powder. The process involves spraying a liquid feedstock into a hot gas stream, which evaporates the solvent and leaves behind small, spherical particles. Coagulation, on the other hand, involves the aggregation of smaller particles into larger, more stable particles. This method is often used when a specific particle size distribution or shape is required. Fluidized bed granulation, finally, is a technique that combines drying and granulation in a single step. It is particularly useful for producing redispersible powders with good flow properties and high compactibility.

3.2.1 Absorption, distribution, metabolism and excretion
- The global market for hydroxyethyl cellulose has been growing steadily in recent years, driven by increasing demand from various end-use industries such as pharmaceuticals, personal care, and coatings. The increasing demand for eco-friendly and sustainable products has also led to an increased interest in hydroxyethyl cellulose as an alternative to traditional chemical thickeners.
- Hydroxyethyl cellulose (HEC) is a versatile polymer that is widely used in various industries such as pharmaceuticals, construction, and cosmetics. One of the leading suppliers of HEC is Ashland. Ashland is a global leader in specialty chemicals and has been at the forefront of developing innovative solutions for a wide range of applications.

Methyl cellulose and HPMC are two types of cellulose-based polymers commonly used in building materials. However, Methyl Cellulose is gradually being replaced by HPMC due to the higher requirements in modern construction. In addition, some suppliers refer to methyl cellulose as the common name for hydroxypropyl methyl cellulose (HPMC) and Hydroxyethyl methyl cellulose (HEMC). We will explore the difference between HPMC and HEMC in later articles.
- Hydroxypropyl methylcellulose (HPMC) powder, a widely used pharmaceutical and construction material, is an essential component in various industries due to its unique properties. It serves as a binder, thickener, and emulsifier, among other functions. The price of HPMC powder is a critical factor influencing its demand and supply in the global market.
- In the cosmetics industry, HPMC is used in a wide range of personal care products, including lotions, creams, and shampoos. Its solubility in water allows for the creation of stable emulsions and gels, ensuring uniform application and absorption of the product on the skin or hair. HPMC also acts as a film former, providing a protective barrier against external environmental factors.

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).
- HEC, derived from cellulose through ethoxylation, is a non-ionic cellulose ether. It is widely used as a thickening agent, stabilizer, and suspending agent due to its excellent water retention capabilities. HEC's ability to form a gel under certain conditions makes it ideal for applications in construction materials, where it enhances the workability of concrete and mortar. In the pharmaceutical industry, HEC is used in tablet coatings and as a viscosity enhancer in oral and topical formulations.
- Once the appropriate polymer is chosen, it undergoes a sophisticated process called emulsion polymerization. In this phase, the polymer is combined with water and surfactants to form a stable emulsion. The mixture is then subjected to rigorous stirring and heating to initiate the polymerization reaction. This step is crucial as it determines the particle size and distribution of the polymer within the emulsion, factors that significantly impact the ease of redispersion and overall performance.
- In addition to its environmental and versatility benefits, VAE redispersible powder also offers several other advantages
- One of the key advantages of using hydroxyethylcellulose is its ability to create a uniform and stable consistency in products. Its thickening properties make it an ideal ingredient in lotions, creams, and gels, where a smooth and even texture is desired. It also helps to improve the shelf life of products by preventing separation or settling of ingredients.
