Trick Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies easily in chilly water yet does not dissolve in hot water over its gelation temperature level. The product creates clear, anemic services with excellent film-forming ability.

Typical viscosity varieties from 5 mPa · s zu 100,000 mPa · s (bestëmmt op 2% Konzentratioun, 20 °C), op de Grad vertrauen. Wetness content stays below 5% (no Gewiicht). De pH vun a 2% remedy normally falls in between 4.0 an 8.0.

Pureness and Top Quality Standards

This HPMC fulfills pharmacopeial criteria such as USP-NF, EP, and JP when made use of in pharmaceutical applications. For industrial or building uses, it complies with appropriate technological requirements. Hefty metals are kept under 10 ppm. Residue on ignition stays below 1.5%. Microbial limits comply with basic guidelines: overall cardio count ≤ 100 CFU/g, yeast and mold and mildew ≤ 10 CFU/g, and absence of E. coli an Salmonella.

Stockage an Ëmgank

Shop HPMC an engem super, dréchen Plaz ewech vun direktem Sonneliicht. Keep containers firmly near protect against wetness absorption. Use basic commercial health techniques when handling. Prevent creating dirt.

Gemeinsam Uwendungen

HPMC is commonly made use of in pharmaceuticals as a binder, thickener, or controlled-release agent in tablets. Am Gebai, it boosts workability and water retention in cement-based items like tile adhesives and provides. It also serves as a stabilizer in food, Kosmetik, an Faarwen.

Applications of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Uwendungen vun Hydroxypropyl Methyl Cellulose (HPMC) CAS 9004-65-3

Bau- a Baumaterial

HPMC is commonly used in dry-mix mortars, Keramik Fliesen Klebstoff, an selbstnivellerende Verbindungen. It boosts water retention so cement can completely hydrate. This leads to more powerful bonds and much better workability. Builders also depend on HPMC to reduce drooping and prolong open time throughout application.

Drogen

An Pëllen a Pëllen, HPMC funktionéiert als Bindemëttel, Film-Beschichtung Agent, oder kontrolléiert-Release Matrixentgasung. It liquifies gradually in the digestive tract, aiding active ingredients launch at the appropriate rate. Because it is non-toxic and steady, regulative companies approve it for dental use worldwide.

Liewensmëttel Maart

HPMC wierkt als Verdickung, Emulgator, and stabilizer in numerous refined foods. Dir kënnt et an Zoossen fannen, Glace, a Gluten-gratis Bäckereien. It helps keep appearance and avoids separation without changing taste.

Perséinlech Behandlung a Kosmetik

Shampoos, Lotionen, and tooth pastes frequently consist of HPMC. It gives products a smooth feel and keeps ingredients equally combined. Its film-forming capacity additionally aids skincare products remain on the skin much longer.

Faarwen a Beschichtungen

Suppliers add HPMC to water-based paints to control thickness and stop splattering. It increases pigment suspension and makes brushing easier. The outcome is an uniform do with less brush marks.

Landwirtschaft

In chemical and fertilizer formulations, HPMC works as a carrier and adhesive. It aids active components adhere to plant surfaces and slows down drainage after rain. This increases efficiency and reduces waste.
