– Methoxy cov ntsiab lus: 19%– 30%.
– Hydroxypropoxy web cov ntsiab lus: 4%– 32%.

Purity and Quality Requirements

HPMC fulfills significant pharmacopeial standards, including USP-NF, EP, thiab JP, when made use of in pharmaceutical applications. For industrial or building usages, it abides by relevant technical specifications. Heavy steels are limited to ≤ 20 ppm ua. Recurring solvents like methanol and isopropanol remain listed below safety and security limits. Microbial restrictions adhere to industry norms (e.g., complete aerobic matter ≤ 100 CFU/g).

Tej kev siv

This raw material is widely made use of in:.
– Pharmaceuticals: As a binder, txheej neeg sawv cev, los yog tswj-tso matrix nyob rau hauv cov ntsiav tshuaj computers.
– Tsev: In cement-based products for enhanced workability and water retention.
– Khoom noj khoom haus: As a thickener or stabilizer (where allowed).
– Individual treatment: In hair shampoos, tshuaj pleev, and tooth paste for texture control.

Storage needs to remain in an amazing, dry location in secured containers to prevent moisture uptake. Service life is usually 24 months under appropriate problems.

Applications of Chemical Raw Material Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Kev siv ntawm Hydroxypropyl Methyl Cellulose (HPMC)– CAS 9004-65-3

Kev tsim kho thiab kev tsim khoom

HPMC is commonly made use of in cement-based products like tile adhesives, self-leveling compounds, thiab plasters. It enhances workability by retaining water throughout the healing procedure. This aids prevent cracks and makes certain strong bonding. Building contractors rely on HPMC for constant performance in dry-mix mortars.

Pharmaceuticals

Hauv tshuaj, HPMC work as a binder, zaj duab xis-txheej txheem, los yog tswj-tso matrix nyob rau hauv cov ntsiav tshuaj computers. It liquifies gradually in the digestive system system, permitting drugs to launch continuously over time. The compound is safe and approved for use in oral medicines worldwide.

Kev lag luam zaub mov

HPMC ua hauj lwm raws li ib tug thickener, emulsifier, and stabilizer in lots of refined foods. It assists keep appearance and protects against component splitting up in items like sauces, gelato, and gluten-free baked products.
