Hidroxipropil metil zelulosa (HPMC)– Produktuaren zehaztapenak

Chemical Identity

Hidroxipropil metil zelulosa (HPMC) erdi-sintetikoa da, zelulosaz egindako polimero ur disolbagarria. It appears as a white to beige powder. The material has no odor and is non-toxic. HPMC satisfies food, farmazia, and industrial grade standards.

Egoitza Fisikoak

The powder flows easily and dissolves conveniently in cool water. It forms a clear to slightly over cast thick remedy. HPMC does not liquify in warm water above 70 ° C but will gel when heated up. As soon as cooled, it redissolves. Its thickness ranges from 5 mPa · s to over 100,000 mPa · s, kalitatean oinarrituz.

Pureness and Structure

Regular HPMC consists of:
– Methoxy groups: 19%– 30%.
– Hydroxypropoxy groups: 4%– 32%.
– Hezetasun edukia: ≤ 5%.
– Ash web edukia: ≤ 1.5%.
– pH (2% irtenbidea): 4.0– 8.0.

Hefty metals and microbial limits comply with pertinent pharmacopeial demands (adib., USP/NF, EP, JP).

Functional Performance

HPMC works well as a thickener, aglutinatzailea, aurreko pelikula, eta ura atxikitzeko agentea. In construction products like floor tile adhesives and provides, it aids maintain water in the mix much longer, enhancing workability and attachment. Drogetan, it controls drug launch and functions as a tablet binder. Janarian, it stabilizes solutions and enhances appearance.

Biltegiratzea eta manipulazioa

Store HPMC in an amazing, leku lehorra hezetasunetik urrun. Maintain containers securely shut. The service life is generally 24 months when saved correctly. Avoid call with strong oxidizing representatives. Use common industrial health practices throughout handling.

Hidroxipropil metil zelulosaren aplikazioak (HPMC)

Eraikuntza-materialak

HPMC is widely made use of in building items like ceramic tile adhesives, cement plasters, eta substantzia autonivelatzaileak. It assists control water retention so cement can heal properly. This enhances workability and minimizes splitting. Contractors depend on HPMC to make mixes smoother and easier to spread out.

Drogak

Medikuntzan, HPMC acts as a binder, geruzaren ordezkaria, or controlled-release component. It is secure for human usage and liquifies slowly in the body. Medication manufacturers include it to tablet computers to assist them hold form or launch medicine in time. Eye decreases likewise make use of HPMC to keep wetness on the eye surface area.

Elikagaien Merkatua

HPMC jobs as a thickener, egonkortzailea, or emulsifier in numerous foods. Saltsetan aurki dezakezu, esnekien alternatibak, eta labean egindako gaiak. It aids maintain textures consistent and avoids active ingredients from dividing. Because it is plant-based and non-digestible, it matches vegan and low-calorie diet regimens.

Personal Treatment Products

Toothpaste, xanpuak, and creams usually consist of HPMC. It gives these products a smooth feeling and assists them remain combined. In toothpaste, it holds water and maintains the paste from drying out. Ukenduetan, it develops a light movie that locks in dampness.

Agriculture

Farmers usage HPMC in seed finishes and pesticide formulas. It aids active ingredients adhere to plants and release gradually. This increases performance and cuts down on waste. Seed treatments with HPMC likewise sustain much better germination in dry conditions.

Pinturak eta Estaldurak

Paint manufacturers include HPMC to enhance structure and application. It quits pigments from settling and makes paint circulation uniformly. Wall surfaces obtain an uniform finish without drips or brush marks. The additive also assists paint withstand splashing during use.
