Hydroxypropyl Methylcellulose (HPMC), a non-ionic cellulose ether with CAS number 9004-65-3, is a workhorse in the pharmaceutical industry, serving a multitude of essential roles as an excipient. Its versatility stems from its unique blend of physical and chemical properties, making it indispensable in the formulation of solid dosage forms, liquid preparations, and even advanced drug delivery systems. As a dedicated manufacturer and supplier of high-purity chemical ingredients, we understand the critical importance of HPMC in ensuring the quality and performance of pharmaceutical products.

In tablet manufacturing, HPMC excels as a binder, facilitating the granulation process that improves powder flowability and compressibility. This leads to tablets with consistent weight and hardness. Its film-forming properties are perhaps its most recognized application, where it forms a smooth, protective, and often aesthetically pleasing coating on tablets. This film coating not only masks unpleasant tastes and odors but also protects the drug from environmental degradation and can be modified to achieve sustained or controlled drug release. For a controlled release matrix, HPMC forms a gel layer upon contact with gastrointestinal fluids, modulating the rate at which the API is released.

Beyond solid dosage forms, HPMC is widely used in liquid preparations. It acts as a thickening agent in suspensions and syrups, improving palatability and ensuring uniform drug distribution. Its ability to form colloidal solutions also makes it suitable for ophthalmic applications as an artificial tear lubricant, providing relief from dry eye symptoms. The stability and inertness of HPMC, combined with its compliance with international pharmacopeia standards (USP, BP, EP, CP), make it a safe and reliable choice for these sensitive applications.

For pharmaceutical companies seeking to buy HPMC, partnering with a reputable manufacturer and supplier is paramount. Our production processes are designed to ensure consistent quality, purity, and precise control over HPMC's key characteristics, such as viscosity and degree of substitution. This consistency is vital for predictable formulation performance and regulatory compliance. We offer a range of HPMC grades tailored to specific pharmaceutical applications, ensuring you find the optimal product for your needs.
