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 kanggo 100,000 mPa · s (ditemtokake ing 2% concentration, 20 ° C), relying on the grade. Wetness content stays below 5% (kanthi bobot). pH saka a 2% remedy normally falls in between 4.0 lan 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 lan Salmonella.

Panyimpenan lan Penanganan

Shop HPMC in a great, panggonan garing adoh saka sinar srengenge langsung. Keep containers firmly near protect against wetness absorption. Use basic commercial health techniques when handling. Prevent creating dirt.

Aplikasi umum

HPMC is commonly made use of in pharmaceuticals as a binder, pengawet, or controlled-release agent in tablets. Ing bangunan, it boosts workability and water retention in cement-based items like tile adhesives and provides. It also serves as a stabilizer in food, kosmetik, and paints.

Applications of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Aplikasi saka Hydroxypropyl Methyl Cellulose (HPMC) CAS 9004-65-3

Construction and Building Materials

HPMC is commonly used in dry-mix mortars, adhesives kothak keramik, lan senyawa self-leveling. 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.

Obat-obatan

Ing tablet lan pil, HPMC function as a binder, agen lapisan film, utawa kontrol-release matriks. 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.

Pasar Pangan

HPMC acts as a thickener, pengemulsi, and stabilizer in numerous refined foods. You can locate it in sauces, ice cream, and gluten-free baked products. It helps keep appearance and avoids separation without changing taste.

Perawatan Pribadi lan Kosmetik

Shampoos, lotion, 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.

Paint lan Coatings

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.

Agriculture

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.
