Introduction to Hydroxypropyl Methyl Cellulose HPMC E5 E15 Chemical CAS 9004 65 3

Hydroksypropylmetylcellulose (HPMC), hvis kinesiske navn er hydroksypropylmetylcellulose, er en halvsyntetisk, ikke-ionisk celluloseeter oppnådd ved kjemisk modifisering av naturlig cellulose. Dette hvite pulveret kan danne en gjennomsiktig viskøs løsning etter oppløsning i vann. Den har utmerket fortykning, vannretensjon, stabilitet og filmdannende egenskaper. Det er et uunnværlig multifunksjonelt tilsetningsstoff på mange områder som konstruksjon.

Characteristics and advantages of Hydroxypropyl Methyl Cellulose HPMC E5 E15 Chemical CAS 9004 65 3

Utmerket vannløselighet: Det kan raskt løses i kaldt vann for å danne en klar og stabil løsning.

Effektiv fortykkelse og vannretensjonsevne: Øk viskositeten til materialet, reduserer vannfordampning effektivt, og forbedre arbeidseffektiviteten.

God stabilitet: Den har god stabilitet mot syrer, alkalier, og salter, og er egnet for et bredt spekter av pH-verdier.

Hydroksypropylmetylcellulose (HPMC)– Grades E5 & E15

Produktsammendrag

Hydroksypropylmetylcellulose (HPMC), CAS-nr. 9004-65-3, er en halvsyntetisk, vannløselig polymer laget av cellulose. It is widely used as a thickener, binder, film former, and stabilizer in several industries. The E5 and E15 qualities are amongst one of the most common types. They differ mostly in viscosity and alternative levels, which impact their performance in different applications.

Trikskrav

Kjemisk samtale: Hydroksypropylmetylcellulose
CAS-nummer: 9004-65-3
Metoksyinnhold: 19%– 30%.
Hydroxypropoxy Web content: 4%– 32%.
pH (2% service): 4.0– 8.0.
Tap ved tørking: ≤ 5.0%.
Ask innhold: ≤ 1.5%.

The E5 quality has a reduced viscosity, generelt rundt 5 mPa · s in a 2 % flytende alternativ kl 20 °C. The E15 grade reveals a little higher viscosity, averaging regarding 15 mPa · s under the exact same problems. Both qualities dissolve conveniently in cold water but do not liquify in warm water above their gelation temperature (typisk 50– 70 °C).

Søknader

HPMC E5 and E15 are made use of in pharmaceuticals as tablet computer binders and controlled-release representatives. I bygningen, they boost workability and water retention in cement-based items like floor tile adhesives and renders. I mat, HPMC acts as an emulsifier or foam stabilizer (approved as E464). It is also discovered in cosmetics, maling, and farming formulas where consistent appearance and stability matter.

Bruk av hydroksypropylmetylcellulose (HPMC) E5 and E15

Hva er HPMC?

Hydroksypropylmetylcellulose (HPMC), med CAS-nummer 9004-65-3, is a plant-based polymer widely used in food, narkotika, og kosmetikk. Qualities E5 and E15 are common in markets that need risk-free, reliable active ingredients.

Use in Food Products

I mat, HPMC E5 and E15 job as thickeners, stabilizers, and emulsifiers. They assist maintain active ingredients combined equally and improve appearance. You’ll locate them in gluten-free baked goods, where they replace the binding power of gluten. They likewise stop ice crystals from forming in frozen desserts, offering a smoother mouthfeel. Since HPMC is non-digestible, it includes fiber without affecting preference or calories.

Role in Pharmaceuticals

Pharmaceutical manufacturers utilize HPMC E5 and E15 to manage just how quick a medication liquifies in the body. It’s typically part of tablet finishings that postpone launch until the tablet reaches the best place in the digestive system tract. This helps reduce belly irritability and makes medication a lot more efficient. HPMC additionally works as a binder in pills, holding energetic ingredients with each other without reacting with them.

Advantages in Cosmetics

I kremer, kremer, and hair shampoos, HPMC provides a rich, jevn følelse. Den holder godt på vannet, which assists skin remain hydrated. It also maintains solid bits put on hold so items do not different gradually. Because it’s mild and non-irritating, it’s safe for sensitive skin and everyday use.

Why Select HPMC E5 and E15?

These qualities meet strict safety and security standards for human usage and topical usage. They dissolve conveniently in chilly water, stay steady throughout a series of temperatures, and function well with other common active ingredients. Their flexibility and integrity make them a top selection for formulators that need constant performance in every batch.
