  • In the pharmaceutical industry, HPMC is used as a binder, film former, and viscosifier in tablets, capsules, and ointments. The grade of HPMC used in pharmaceutical applications is usually of high purity to meet strict regulatory standards. HPMC helps control the release of active ingredients, improve drug solubility, and provide a smooth texture to the final product.
  • Residues of cellulose and breakdown products in edible tissues and products from animals fed HPMC are not expected. Although the (partial) degradation of HPMC would eventually occur in some species (ruminants, hindgut fermenters), breakdown products would still likely be of high molecular weight and poorly or not absorbed; the short-chain fatty acids resulting from microbial breakdown of cellulose in the rumen or hindgut will enter the physiological pools of the animals. The consumer would therefore not be exposed to the additive or derived products when consuming edible tissues and products from animals given diets containing HPMC. Consequently, the FEEDAP Panel concludes that the use of HPMC in animal nutrition is of no concern for consumer safety.

  • At its core, HPMC consists of a linear chain of glucose units, which are the building blocks of cellulose. These glucose units are connected by beta-1,4-glycosidic bonds, forming a long, unbranched polymer. However, what sets HPMC apart from native cellulose is the introduction of hydroxypropyl and methyl groups through a process called etherification.
  • Emulsifier in ointments
  • Furthermore, Ashland's hydroxyethyl cellulose is utilized in the food industry as a stabilizer, emulsifier, and thickener. It improves the consistency and mouthfeel of sauces, dressings, and desserts. Additionally, it can act as a fat substitute in low-calorie products without compromising taste or texture.

  • It is also important to note that HPMC can interact with certain medications. If you are taking any medications, especially those that affect your digestion or bowel movements, it is important to speak with your healthcare provider before using products containing HPMC.
  • VAE powder is a fine, free-flowing substance that combines the benefits of both vinyl acetate and ethylene. The vinyl acetate component imparts excellent adhesion and film-forming characteristics, while the ethylene contributes to improved flexibility and durability. This blend results in a product that is not only robust but also adaptable to various conditions and surfaces.
  • When it comes to buying HPMC, the first step is to determine your specific requirements. Different grades of HPMC are available, each tailored for specific applications. For instance, pharmaceutical grade HPMC is highly purified and used in tablet coatings and controlled drug release systems, while construction grade HPMC is used as a binder in plaster and mortar.
