Introduction to Chemical Raw Material Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Hydroxypropyl Methylcellulose (HPMC), ki gen non Chinwa se hydroxypropyl methylcellulose, se yon semi-sentetik, etè seluloz ki pa iyonik ki te jwenn nan modifye chimik seluloz natirèl. Poud blan sa a ka fòme yon solisyon gluan transparan apre li fin fonn nan dlo. Li gen ekselan epesman, retansyon dlo, estabilite ak pwopriyete fim-fòme. Li se yon aditif multifonksyonèl endispansab nan anpil jaden tankou konstriksyon.

Characteristics and advantages of Chemical Raw Material Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Ekselan solubilite dlo: Li ka byen vit fonn nan dlo frèt pou fòme yon solisyon klè ak ki estab.

Epesman efikas ak kapasite retansyon dlo: Ogmante viskozite materyèl la, efektivman redwi evaporasyon dlo, ak amelyore efikasite travay.

Bon estabilite: Li gen bon estabilite nan asid, alkali, ak sèl, epi li apwopriye pou yon pakèt valè pH.

Efè fim-fòme ak pwoteksyon: Apre siye, li fòme yon fim difisil ak transparan pou pwoteje substra a epi anpeche pénétration dlo ak evaporasyon.

Ki pa toksik ak ki pa irite: Li gen bon biocompatibility epi li apwopriye pou jaden medikaman ak manje.

Ajistebilite: Lè w chanje degre sibstitisyon ak pwa molekilè, pèfòmans li yo ka ajiste pou satisfè kondisyon aplikasyon diferan.

Trick Physical and Chemical Features

HPMC dissolves quickly in cold water to form a clear, epè remèd. It does not dissolve in hot water above its gelation temperature (usually 50– 90 °C, depann sou bon jan kalite). The product is non-ionic and secure over a broad pH variety (3– 11). It shows excellent film-forming capacity, retansyon dlo, and thickening efficiency.

Viscosity varies by item grade. Usual thickness arrays include 5 mPa · s to 100,000 mPa · s (mezire kòm yon 2% solisyon nan 20 °C). Substitution degrees are managed to satisfy details application needs:.
– Kontni metoksik: 19%– 30%.
– Kontni entènèt Hydroxypropoxy: 4%– 32%.

Purity and Quality Requirements

HPMC fulfills significant pharmacopeial standards, ki gen ladan USP-NF, EP, ak 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 (pa egzanp, complete aerobic matter ≤ 100 CFU/g).

Aplikasyon tipik

This raw material is widely made use of in:.
– Famasetik: As a binder, reprezantan kouch, or controlled-release matrix in tablet computers.
– Bilding: In cement-based products for enhanced workability and water retention.
– Food: As a thickener or stabilizer (kote yo pèmèt).
– Individual treatment: In hair shampoos, losyon, 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

Aplikasyon 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, konpoze oto-nivelman, ak andui. 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.

Famasetik

Nan medikaman, HPMC work as a binder, film-coating representative, or controlled-release matrix in tablet 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.

Endistri Manje

HPMC serves as a thickener, emulsifyan, and stabilizer in lots of refined foods. It assists keep appearance and protects against component splitting up in items like sauces, krèm glase, ak pwodwi kwit san gluten. Regulative agencies acknowledge it as risk-free for consumption under particular use degrees.

Penti ak penti

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.

Cosmetics and Personal Treatment

Nan losyon, chanpou, 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.

Agrikilti

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.
