HPMC powder is a white powder made from natural polymer cellulose, odorless and tasteless, soluble in cold water, forming a transparent and viscous solution. This material has good water retention and adhesion, so it is widely used in various industries such as construction, food, cosmetics, etc.
In the field of medicine, the new uses of HPMC powder have attracted people’s attention. Researchers have found that HPMC powder can serve as a thickener for tablets, improving their formability and stability and making them smoother and more accessible to swallow. In addition, HPMC powder can also serve as a solvent to help other pharmaceutical components dissolve and disperse better, improving the bioavailability of drugs. Most importantly, HPMC powder can also serve as a sustained-release agent to control the release rate of drugs, allowing them to be slowly released within a predetermined time, thereby prolonging the efficacy time.
This discovery has brought new development opportunities to the pharmaceutical industry. In the future, pharmaceutical companies can utilize the characteristics of HPMC powder to develop more efficient, safe, and convenient drug formulations to meet the needs of patients. At the same time, the widespread application of HPMC powder will further promote the progress of its production technology and cost reduction, benefiting more patients.
HPMC powder is a white or almost white powder substance mainly made from natural polymer material cellulose through a series of chemical processes. It is a type of non-ionic cellulose ether that has various properties such as thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention, and protective colloid.
Characteristics of HPMC powder
- Appearance: HPMC powder is a white or almost white powder.
- Particle size: The 100 mesh pass rate of HPMC powder is more significant than 98.5%, and the 80 mesh pass rate is more important than 100%.
- Surface tension: The surface tension of HPMC aqueous solution is 2%, and that of aqueous solution is 42-56dyn/cm.
- Solubility: HPMC powder is easily soluble in cold water, forming a transparent and viscous solution with high water retention.
- Performance: HPMC powder has properties such as thickening, adhesion, dispersion, emulsification, film-forming, suspension, adsorption, gelation, surface activity, water retention, and protective colloid.
- Stability: HPMC powder has the characteristics of low salt resistance, pH stability, water retention, size stability, excellent film-forming ability, and extensive enzyme resistance, dispersibility, and adhesion.
Application of HPMC powder
- Construction industry: HPMC powder is mainly used as a water-binding agent and retarder for cement mortar in the construction industry, making the mortar pumpable. It can also be used as an adhesive for plastering, gypsum, putty powder, or other building materials, improving coating properties and extending operational time.
- Pharmaceutical industry: In the pharmaceutical field, HPMC powder can be used as a thickener, solvent, and sustained-release agent for tablets.
- Food industry: In the food industry, HPMC powder can be used for the production of plant-based protein beverages, dairy products, and candies.
- Cosmetics industry: In cosmetics, HPMC powder can be used as an emulsifier, thickener, and moisturizer.
- Other industries: HPMC powder is also widely used in other sectors such as petroleum, textiles, papermaking, coatings, etc. In the paint industry, it can be used as a thickener, dispersant, and stabilizer to improve the performance of coatings.
