HPMC is a semi-synthetic polymer derived from cellulose, modified through chemical processes to enhance its solubility and functional properties. Its chemical structure combines hydroxypropyl and methyl groups, which contribute to its unique characteristics. Unlike traditional cellulose derivatives, HPMC exhibits excellent water solubility, thermal stability, and film-forming capabilities, making it ideal for diverse applications.
One of the standout features of HPMC is its ability to act as a viscosity modifier. This property allows it to regulate the flow and consistency of formulations, ensuring optimal performance in both liquid and solid states. Additionally, HPMC serves as a stabilizer, preventing phase separation and maintaining product integrity over time.
HPMC’s versatility stems from its distinct properties, which include:
HPMC’s unique characteristics make it an invaluable ingredient across multiple sectors. Below are some of its key advantages:
In construction, HPMC is widely used in mortar and plaster formulations. It improves workability by reducing water demand and enhancing adhesion to surfaces. HPMC also prevents slumping and cracking, ensuring durable, high-quality finishes.
HPMC is a critical excipient in drug delivery systems. It acts as a film-forming agent for tablets and capsules, improving their mechanical strength and dissolution rates. Additionally, HPMC is used in controlled-release formulations, allowing for the sustained release of active ingredients.
In food processing, HPMC functions as a thickener and stabilizer, enhancing the texture and shelf life of products. It is commonly found in dairy alternatives, sauces, and baked goods, where it prevents separation and maintains a smooth consistency.
HPMC is a key component in personal care and cleaning products. Its emulsifying properties help blend oil and water-based ingredients, while its film-forming ability improves the performance of coatings and adhesives.

| Parameter | Specification |
|---|---|
| Chemical Formula | C6H10O5 (modified with hydroxypropyl and methyl groups) |
| Molecular Weight | Varies depending on substitution level (typically 40,000–1,000,000 g/mol) |
| Viscosity (2% solution) | 10–1,000,000 mPa·s (depending on grade) |
| Water Solubility | Highly soluble in cold water; insoluble in organic solvents |
| pH Range | 4–10 (stable under neutral to slightly acidic conditions) |
| Thermal Stability | Retains properties up to 150°C |
| Biodegradability | Biodegradable under aerobic and anaerobic conditions |
The technical specifications of HPMC are tailored to meet the demands of specific applications. For instance, high-viscosity grades are preferred in pharmaceutical coatings, while low-viscosity variants are ideal for food emulsions. The substitution level of hydroxypropyl and methyl groups also influences the polymer’s solubility and performance.
HPMC’s adaptability allows it to address a wide range of industrial challenges. Below are some of its most common application scenarios:
In dry-mix mortars, HPMC improves water retention, ensuring proper hydration of cement and reducing the risk of cracking. It also enhances the workability of the mixture, making it easier to apply.
HPMC is used in tablets and capsules to improve disintegration and dissolution rates. Its film-forming ability makes it an excellent choice for enteric coatings, which protect drugs from gastric acid.
In the food sector, HPMC is employed as a stabilizer in dairy products, sauces, and frozen desserts. It prevents ice crystal formation in frozen foods and maintains the texture of emulsions, such as salad dressings and mayonnaise.
HPMC is a key ingredient in shampoos, lotions, and toothpaste. Its thickening properties enhance product consistency, while its film-forming ability improves the adhesion of coatings.
