The product is non-ionic and secure over a broad pH variety (3– 11). It shows excellent film-forming capacity, wetter fêsthâlden, en thickening effisjinsje.

Viscosity varies by item grade. Usual thickness arrays include 5 mPa · s oan 100,000 mPa · s (gauged as a 2% oplossing by 20 °C). Substitution degrees are managed to satisfy details application needs:.
– Methoxy ynhâld: 19%– 30%.
– Hydroxypropoxy web ynhâld: 4%– 32%.

Purity and Quality Requirements

HPMC fulfills significant pharmacopeial standards, including USP-NF, EP, and 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. Recurring solvents like methanol and isopropanol remain listed below safety and security limits. Microbial restrictions adhere to industry norms (bgl., complete aerobic matter ≤ 100 CFU/g).

Typyske applikaasjes

This raw material is widely made use of in:.
– Pharmaceuticals: As a binder, laach fertsjintwurdiger, of matrix mei kontrolearre frijlitting yn tabletkompjûters.
– Gebou: In cement-based products for enhanced workability and water retention.
– Iten: As a thickener or stabilizer (wêr tastien).
– Individual treatment: In haarshampoos, lotions, 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

Tapassingen fan Hydroxypropyl Methyl Cellulose (HPMC)– CAS 9004-65-3

Bouw- en Bouwprodukten

HPMC is commonly made use of in cement-based products like tile adhesives, selsnivellerende ferbiningen, en pleisters. 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

Yn medisinen, HPMC work as a binder, film-coating fertsjintwurdiger, of matrix mei kontrolearre frijlitting yn tabletkompjûters. 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.

Food Yndustry

HPMC serves as a thickener, emulgator, and stabilizer in lots of refined foods. It assists keep appearance and protects against component splitting up in items like sauces, iis, en glutenfrije bakte produkten. Regulative agencies acknowledge it as risk-free for consumption under particular use degrees.

Paints en Coatings

Repaint producers include HPMC to water-based formulations to regulate thickness and enhance application. It stops pigments from working out and offers a smooth surface. The additive additionally boosts open time, allowing painters function much longer prior to the covering dries out.
