Hydroxypropyl methylcellulose (HPMC), with the CAS number 9004-65-3, is a high-performance multifunctional thickener and stabilizer that has become indispensable in construction, medicine, food, and daily chemical industries. Developed by Hebei Tangzhi Technology Co., Ltd., this polymer combines exceptional rheological properties with environmental sustainability, making it a preferred choice for global manufacturers.
HPMC is a semi-synthetic, non-toxic, and biodegradable cellulose ether derived from natural wood pulp. Its unique chemical structure—composed of hydroxypropyl and methyl groups attached to a glucose polymer chain—provides remarkable water retention, film-forming ability, and viscosity control. These characteristics enable HPMC to function as a thickener, emulsifier, and binding agent across diverse applications.

HPMC is a critical component in tile adhesives, mortars, and renders. Its water retention properties prevent slippage and ensure strong bonding, even in high-temperature environments. According to NIST (National Institute of Standards and Technology), polymers like HPMC play a vital role in optimizing material performance under variable climatic conditions.
In drug formulation, HPMC acts as a binder, disintegrant, and controlled-release agent. It enhances tablet hardness and ensures uniform drug distribution. The U.S. Food and Drug Administration (FDA) recognizes HPMC as a safe excipient for oral and topical medications.
As a food-grade thickener, HPMC improves texture in dairy products, sauces, and baked goods. Its ability to stabilize emulsions and prevent syneresis makes it ideal for processed foods. The NIST has published guidelines on polymer use in food packaging, emphasizing HPMC's role in extending shelf life.
HPMC is used in toothpaste, detergents, and cosmetics to maintain product consistency and prevent separation. Its film-forming properties create a protective barrier on surfaces, enhancing product longevity.
