Hydroxypropyl Methyl Cellulose (HPMC), with the CAS number CAS 9004-65-3, is a high-performance multifunctional thickener and stabilizer that has become a cornerstone in various industrial applications. This article delves into the core features, technical specifications, and real-world applications of HPMC, while highlighting the expertise of its manufacturer, Hebei Tangzhi Technology Co., Ltd., a leading producer of cellulose derivatives in China.
HPMC is a semi-synthetic, non-toxic polymer derived from natural cellulose. Its unique chemical structure combines hydroxypropyl and methyl groups, granting it exceptional solubility, film-forming properties, and thermal stability. These characteristics make it a preferred choice in industries ranging from construction to pharmaceuticals.

HPMC is a critical component in cement-based products such as mortars, plasters, and tile adhesives. Its water-retention properties improve the workability of concrete mixtures, while its film-forming ability enhances adhesion and reduces cracking. 
In drug formulation, HPMC acts as a binder, disintegrant, and controlled-release agent. It ensures uniform drug distribution and extends the shelf life of tablets and capsules. The polymer's biocompatibility aligns with NIST standards for pharmaceutical materials, as outlined in their metrology research.
HPMC is used as a food additive to improve texture, stability, and shelf life. It is commonly found in dairy products, sauces, and baked goods, where it functions as an emulsifier and thickener. Its non-GMO and non-allergenic properties make it a preferred choice for health-conscious consumers.
The polymer's ability to form stable gels and emulsions makes it a popular ingredient in lotions, shampoos, and toothpaste. HPMC enhances product consistency and ensures even distribution of active ingredients.
