  • What is HPMC?
    Characterized as off-white, HPMC is a cellulose polymer that has undergone chemical modification but is still considered to be safe for consumption by people. Full formulae written as     Hydroxypropyl methylcellulose is a non-toxic, odorless, water-soluble polymer that is used in many industries for its hydrophilic properties. It is also used as a food additive in the US and cosmetics for its moisturizing and smoothing effects. It should be noted that Hydroxypropyl methylcellulose cannot be digested by the human digestive system and passes through the digestive tract as it is.

  • Understanding HPMC's solubility is critical for formulators and researchers. It helps in selecting the right grade and adjusting processing conditions to achieve the desired properties in end-products. The chart serves as a practical tool, simplifying the complex relationship between HPMC, solvent type, temperature, and particle size.
  • Hydroxypropyl methylcellulose (HPMC) and carboxymethyl cellulose (CMC) are two widely used cellulose derivatives in various industries. They are commonly used as thickening agents, binders, emulsifiers, and stabilizers in food, pharmaceuticals, cosmetics, and construction materials.
  • Bulking agent
  • Acetone and ethyl acetate, being polar aprotic solvents, can dissolve HPMC effectively due to their ability to disrupt the intermolecular forces within the polymer structure
  • Conclusion
  • HPMC also exhibits excellent binding properties, making it an ideal choice for use as an adhesive
  • HPMC is a synthetic polymer derived from cellulose and is commonly used as a thickening, stabilizing, and emulsifying agent in a wide range of products, including pharmaceuticals, cosmetics, and food.
