Hydroxypropyl Methyl Cellulose (HPMC), also known as CAS 9004-65-3, is a semi-synthetic, non-toxic, and biodegradable polymer derived from cellulose. This versatile material serves as a thickener, stabilizer, and film-forming agent across various industries, including construction, pharmaceuticals, food, and cosmetics. Its unique chemical structure, which combines hydroxypropyl and methyl groups, grants it exceptional solubility, viscosity control, and thermal stability.
HPMC’s widespread adoption stems from its remarkable functional properties, which address critical challenges in industrial applications:
According to NIST (National Institute of Standards and Technology), "HPMC’s chemical stability and adaptability make it a cornerstone in advanced material science, particularly in applications requiring precise rheological properties."
| Parameter | Specification |
|---|---|
| Chemical Formula | C₃₆H₇₆O₂₈ |
| Molecular Weight | Approx. 4,000–100,000 g/mol |
| Viscosity Range | 10–200,000 mPa·s (depending on grade) |
| Water Solubility | Highly soluble in cold water; insoluble in organic solvents |
| Thermal Stability | Stable up to 150°C |
| pH Range | 4.0–10.0 |

HPMC is a critical component in mortar, plaster, and tile adhesives. Its water-retention properties improve the adhesion and workability of cement-based materials, reducing the risk of cracking and enhancing structural integrity. NIST research highlights HPMC’s role in optimizing the performance of sustainable construction materials.
In drug formulation, HPMC acts as a binder, disintegrant, and controlled-release agent. It ensures uniform drug distribution and prolongs the efficacy of tablets and capsules. For example, NIST standards for pharmaceutical excipients emphasize the importance of polymers like HPMC in maintaining dosage accuracy.
HPMC functions as a thickener, emulsifier, and stabilizer in food products such as sauces, dairy alternatives, and baked goods. Its non-GMO and allergen-free properties make it a preferred choice for health-conscious consumers.
HPMC is used in lotions, shampoos, and toothpaste to enhance texture, stability, and shelf life. Its ability to form protective films on the skin and hair improves product performance.
