Secret Physical and Chemical Residences

HPMC je neionski celulozni eter, narejen iz naravne celuloze. 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 (običajno 3– 11).

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

Purity and High Quality Criteria

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

Typical assay (dry basis): ≥ 99.5%.
Izguba pri sušenju: ≤ 5.0%.
Residue on ignition: ≤ 1.5%.
Težka jekla (kot Pb): ≤ 10 ppm.
arzen: ≤ 3 ppm.

Prostor za shranjevanje in rokovanje

Nakupujte HPMC v neverjetnem, popolnoma suhem mestu, stran od vlage. Maintain containers securely shut. The shelf life is normally 24 mesecev, ko se pravilno hranijo. Stay clear of direct exposure to guide sunshine or high moisture.

Pogoste aplikacije

HPMC is commonly used in structure materials (like ceramic tile adhesives and provides), zdravila (as a tablet binder or controlled-release agent), hrano (as a thickener or stabilizer), in kozmetiko (for structure and dampness control). Its versatility comes from constant efficiency, varnost, and compatibility with many various other active ingredients.

Uporaba hidroksipropil metil celuloze (HPMC) CAS 9004-65-3

Building and construction Industry

Hidroksipropil metil celuloza (HPMC) plays an essential role in contemporary building and construction products. It is added to cement-based products like ceramic tile adhesives, obliži, in samorazlivne mase. 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.

Droge

V zdravilih, 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.

Živilska tržnica

HPMC is likewise accepted as a preservative (E številka E464). Deluje kot zgoščevalec, stabilizator, in emulgator. You can locate it in low-fat foods, pečeni izdelki, in mlečne možnosti. 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 se pojavi v barvah, kozmetika, and agricultural items. V barvah na vodni osnovi, 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, kemično stabilen, and suitable with lots of other materials.
