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

Hidroksipropylmetielsellulose (HPMC), wie se Chinese naam hidroksipropylmetielsellulose is, is 'n semi-sintetiese, nie-ioniese sellulose-eter verkry deur natuurlike sellulose chemies te modifiseer. Hierdie wit poeier kan 'n deursigtige viskose oplossing vorm nadat dit in water opgelos is. Dit het uitstekende verdikking, waterretensie, stabiliteit en filmvormende eienskappe. Dit is 'n onontbeerlike multifunksionele toevoeging in baie velde soos konstruksie.

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

Uitstekende wateroplosbaarheid: Dit kan vinnig in koue water opgelos word om 'n helder en stabiele oplossing te vorm.

Doeltreffende verdikking en waterretensievermoë: Verhoog die viskositeit van die materiaal, verminder waterverdamping effektief, en werkdoeltreffendheid te verbeter.

Goeie stabiliteit: Dit het goeie stabiliteit teen sure, alkalies, en soute, en is geskik vir 'n wye reeks pH-waardes.

Filmvormende en beskermende effekte: Na droog, dit vorm 'n taai en deursigtige film om die substraat te beskerm en waterpenetrasie en verdamping te voorkom.

Nie-giftig en nie-irriterend: Dit het goeie bioversoenbaarheid en is geskik vir die velde van medisyne en voedsel.

Verstelbaarheid: Deur die graad van substitusie en molekulêre gewig te verander, sy werkverrigting kan aangepas word om aan verskillende toepassingsvereistes te voldoen.

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

Viscosity varies by item grade. Usual thickness arrays include 5 mPa · s aan 100,000 mPa · s (gemeet as 'n 2% oplossing by 20 °C). Substitution degrees are managed to satisfy details application needs:.
– Metoksie inhoud: 19%– 30%.
– Hydroxypropoxy webinhoud: 4%– 32%.

Purity and Quality Requirements

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

Tipiese toepassings

This raw material is widely made use of in:.
– Farmaseutiese middels: As a binder, layer representative, of beheerde-vrystelling matriks in tabletrekenaars.
– Gebou: In cement-based products for enhanced workability and water retention.
– Kos: As a thickener or stabilizer (waar toegelaat).
– Individual treatment: In haarsjampoe, 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

Toepassings van Hydroxypropyl Metiel Sellulose (HPMC)– CAS 9004-65-3

Konstruksie en Bouprodukte

HPMC is commonly made use of in cement-based products like tile adhesives, selfnivellerende verbindings, 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.

Farmaseutiese middels

In medisyne, HPMC work as a binder, filmbedekkingsverteenwoordiger, of beheerde-vrystelling matriks in tabletrekenaars. 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.

Voedselbedryf

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, roomys, en glutenvrye gebakte produkte. Regulative agencies acknowledge it as risk-free for consumption under particular use degrees.

Verf 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.

Skoonheidsmiddels en persoonlike behandeling

In lotions, sjampoe, 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.

Landbou

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.
