Hydroxypropyl Methylcellulose, identified by its CAS number 9004-65-3, is a foundational chemical widely used across numerous industries. As a leading manufacturer and supplier of this essential cellulose ether, we aim to provide valuable insights into its properties, applications, and the critical importance of selecting a reliable source for procurement.

HPMC (CAS 9004-65-3) is a non-ionic polymer derived from cellulose, modified through a process involving methyl and hydroxypropyl groups. This chemical modification imbues it with unique characteristics that make it highly desirable as a functional additive. Its primary roles include acting as a thickener, binder, emulsifier, stabilizer, film-former, and water-retention agent. These multifaceted capabilities make it a go-to ingredient for formulators seeking to enhance product performance and stability.

Key Chemical Properties of HPMC (CAS 9004-65-3):

  • Solubility: HPMC is readily soluble in cold water, forming clear to slightly turbid, viscous solutions. This solubility is crucial for its incorporation into aqueous formulations.
  • Viscosity: It is available in a wide range of viscosity grades, from low to very high, typically measured in centipoise (cP) or millipascal-seconds (mPa·s). This allows formulators to precisely control the rheological properties of their products.
  • Thermal Gelation: An interesting property of HPMC is its ability to undergo thermal gelation – it forms a gel upon heating and liquefies upon cooling. This reversible gelation is beneficial in specific applications, such as in some food products or controlled-release pharmaceutical systems.
  • Film Formation: HPMC can form flexible films, which are useful in coatings for tablets, as well as in cosmetic and haircare products for texture and hold.
  • Water Retention: Particularly important in construction materials like mortars and plasters, HPMC's water retention capabilities prevent rapid drying, extending working time and improving adhesion.

Industry Applications:

  • Construction: Integral to tile adhesives, cement plasters, dry-mix mortars, gypsum products, and EIFS. It improves workability, adhesion, water retention, and anti-sagging properties.
  • Pharmaceuticals: Used as an excipient in tablets (binder, disintegrant, coating agent), ophthalmic solutions, and suspensions, aiding in drug delivery and stability.
  • Food Industry: Functions as a thickener, stabilizer, emulsifier, and binder in dairy products, baked goods, sauces, and beverages.
  • Cosmetics and Personal Care: Enhances texture, provides film-forming properties, stabilizes emulsions, and improves the feel of skincare, haircare, and cleaning products.
