  • Overall, hydroxypropyl methylcellulose is a versatile compound with a wide range of uses in various industries. Its unique properties make it an essential ingredient in many products, from construction materials to pharmaceuticals to food and personal care items. Whether you are building a new structure, taking medication, cooking a meal, or applying makeup, chances are you are benefiting from the many uses of hydroxypropyl methylcellulose.
  • HPMC is commonly used in the formulation of oral solid dosage forms such as tablets and capsules. One of the key properties of HPMC is its ability to act as a binder, which helps to hold the active pharmaceutical ingredients together and improve the cohesion of the tablet matrix. In addition, HPMC can also function as a film-former, coating agent, and controlled-release agent in drug formulations.
  • In the pharmaceutical industry, HEC is used in a variety of applications such as in tablet coatings, ophthalmic solutions, and as a viscosity modifier in oral formulationshydroxyethylhydroxyethyl cellulose cas no. Its water-soluble nature and compatibility with a wide range of other ingredients make it a popular choice for formulators looking to improve the stability and performance of their products.
  • In conclusion, hydroxypropyl methylcellulose (HPMC) is a highly versatile polymer that offers numerous benefits to various industries. Its unique properties make it an ideal excipient for controlled-release formulations, food additives, and cosmetic applications. With its excellent safety profile and wide range of uses, HPMC continues to be a valuable ingredient in many consumer products.

  • Cellulose, a complex carbohydrate abundant in plant cell walls, is the most abundant organic compound on Earth. By introducing hydroxypropyl and methyl groups to cellulose, HPMC is created, altering its water solubility and viscosity characteristics. The percentage of these substituents, often represented as hydroxypropyl% and methyl%, determines the specific properties of the final product.
  • HPMC 4000 is a white to slightly off-white powder that is odorless and tasteless. It is soluble in cold water and forms a transparent viscous solution when dissolved. This makes it an ideal thickening and stabilizing agent in various applications. In the pharmaceutical industry, HPMC 4000 is frequently used as a tablet binder, film former, and coating material. Its ability to control the release of active ingredients in drug formulations is highly valued by pharmaceutical manufacturers.
  • Redispersible Polymer Powders Revolutionizing Construction and Adhesives Industries
  • In the construction industry, HEC is widely used as a rheology modifier in cementitious materials. It improves the workability of concrete, reducing water demand while maintaining pumpability and slump retention. Additionally, it acts as a protective colloid, preventing the precipitation of particles and enhancing the durability of the final product.

  • Hydroxypropyl methyl cellulose (E 464) is identified with the single Chemical Abstracts Service (CAS) number 9004-65-3, and the European Inventory of Existing Chemical Substances (EINECS) number 232-674-9. It is manufactured reacting partially depolymerised cellulose with methyl groups and containing a small degree of hydroxypropyl substitution (Figure 11). Since cellulose is a high molecular weight linear polysaccharide of indeterminate mass and its degree of substitution will depend on the conditions of manufacture, a unique mass and structure cannot be specified. HPMC is in the form of white to off-white powder. A generalised structure of HPMC is shown in Figure 11
