– Methoxy content: 19%– 30%.
– Konten web hydroxypropoxy: 4%– 32%.

Purity and Quality Requirements

HPMC fulfills significant pharmacopeial standards, including USP-NF, EP, lan 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 (contone., complete aerobic matter ≤ 100 CFU/g).

Aplikasi Khas

This raw material is widely made use of in:.
– Farmasi: As a binder, layer representative, utawa kontrol-release matriks ing komputer tablet.
– bangunan: In cement-based products for enhanced workability and water retention.
– Panganan: As a thickener or stabilizer (ngendi diijini).
– Individual treatment: In hair shampoos, lotion, 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

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

Construction and Building Products

HPMC is commonly made use of in cement-based products like tile adhesives, senyawa self-leveling, lan plester. 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.

Farmasi

Ing obat, HPMC work as a binder, film-coating representative, utawa kontrol-release matriks ing komputer tablet. 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.

Industri Pangan

HPMC serves minangka thickener, pengemulsi, 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. Regulative agencies acknowledge it as risk-free for consumption under particular use degrees.

Paint lan 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.

Kosmetik lan Perawatan Pribadi

Ing lotion, sampo, and toothpaste, HPMC supplies structure and stability. It produces a pleasant feeling on the skin or hair without triggering irritability. Its ability to form clear gels makes it suitable for clear cosmetic items.

Agriculture

HPMC is utilized in chemical and fertilizer formulas to improve attachment to plant surface areas. It reduces active component launch, boosting performance and decreasing runoff. Farmers take advantage of much better protection and longer-lasting results.
