(4) Ink printing: As a thickener, dispersant and stabilizer in the ink industry, it has good solubility in water or organic solvents.

HPMC gel is a multifunctional material with diverse applications in pharmaceuticals, food, construction, cosmetics, medical devices, and agriculture. Its unique properties, such as biocompatibility, water solubility and rheology control, contribute to its wide application in various industries. As research and development continue, the potential applications of HPMC gels are likely to expand, making them an increasingly important and versatile material in numerous fields.

Answer: HPMC viscosity is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a product, it typically indicates the measurement of its 2% aqueous solution at a temperature of 20 degrees Celsius.

The benefits of incorporating HPMC into pharmaceutical formulations are manifold. By utilizing HPMC as a matrix former in sustained-release dosage forms, pharmaceutical manufacturers can achieve precise control over drug release, leading to optimized therapeutic outcomes and minimized side effects. Furthermore, HPMC’s bioadhesive properties make it suitable for use in ophthalmic formulations, enhancing the contact time of drugs with ocular tissues and improving the efficacy of treatments for conditions such as glaucoma and dry eye syndrome. Additionally, HPMC’s compatibility with a variety of active pharmaceutical ingredients and its ability to enhance solubility and bioavailability further contribute to its value in pharmaceutical applications, making it a preferred choice for formulators seeking to develop safe, effective, and patient-friendly drug products.
