Hydroxypropyl Methyl Cellulose (HPMC)– Cov Khoom Lag Luam Tshwj Xeeb

Fundamental Info

CAS Number: 9004-65-3
Chemical Call: Hydroxypropyl Methyl Cellulose
Molecular Formula: C₈H₁₆O₆ (duplicating system).
Tsos: Dawb rau dawb, free-flowing powder.

Secret Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies quickly in cold water but does not liquify in warm water over its gelation temperature. The item develops clear, colorless solutions with great film-forming capacity. It stays steady over a large pH array (commonly 3– 11).

Thickness varies by grade. Common thickness varieties consist of 5 mPa · s to 100,000 mPa · s ntawm 2% focus and 20 ° C. This enables customers to select the right kind for their specific demands– whether for enlarging, khi, or water retention.

Purity and High Quality Criteria

The product satisfies major pharmacopeial requirements, suav nrog USP-NF, EP, thiab JP, when used in pharmaceutical applications. For commercial use, it follows appropriate food and building sector standards.

Typical assay (dry basis): ≥ 99.5%.
Poob ntawm ziab khaub ncaws: ≤ 5.0%.
Residue on ignition: ≤ 1.5%.
Cov hlau hnyav (xws li Pb): ≤ 10 ppm.
Arsenic: ≤ 3 ppm.

Cia thiab tuav

Shop HPMC in an amazing, completely dry location away from dampness. Maintain containers securely shut. The shelf life is normally 24 months when kept properly. Stay clear of direct exposure to guide sunshine or high moisture.

Common Applications

HPMC is commonly used in structure materials (like ceramic tile adhesives and provides), tshuaj (as a tablet binder or controlled-release agent), khoom noj khoom haus (as a thickener or stabilizer), thiab tshuaj pleev ib ce (for structure and dampness control). Its versatility comes from constant efficiency, kev nyab xeeb, and compatibility with many various other active ingredients.

Applications of Hydroxypropyl Methyl Cellulose (HPMC) CAS 9004-65-3

Building and construction Industry

Hydroxypropyl methyl cellulose (HPMC) plays an essential role in contemporary building and construction products. It is added to cement-based products like ceramic tile adhesives, o, thiab nws tus kheej theem tebchaw. HPMC boosts workability by maintaining water, which helps cement moisten appropriately. This results in more powerful bonds and less cracks. The compound additionally decreases drying time, providing workers even more time to use and smooth the material.

Tshuaj

In medication, HPMC serves as a secure and effective active ingredient. It is frequently used in tablet computers as a binder or finish representative. The material regulates just how quickly a medicine liquifies in the body, making certain stable release over time. Eye drops typically consist of HPMC also– it serves as a lubricant to eliminate dry skin and irritation. Due to the fact that it is safe and well-tolerated, governing agencies accept its use in many dental and topical medicines.

Kev Ua Lag Luam Khoom Noj Khoom Haus

HPMC is likewise accepted as a preservative (E number E464). It works as a thickener, stabilizer, and emulsifier. You can locate it in low-fat foods, baked products, thiab cov khoom siv mis nyuj. It assists preserve texture and protects against separation of components. Considering that it is plant-based and gluten-free, it suits numerous dietary needs.

Other Makes use of

Past these major areas, HPMC appears in paints, Tshuaj pleev ib ce, and agricultural items. Hauv cov xim dej, it improves viscosity and prevents pigment settling. Skin care lotions utilize it for smooth application and moisture retention. Farmers apply HPMC in seed coatings to sustain germination and secure young plants. Its adaptability originates from being water-soluble, tshuaj lom neeg ruaj khov, and suitable with lots of other materials.
