Specifications of Hydroxypropyl Methyl Cellulose HPMC E5 E15 Chemical CAS 9004 65 3

Hydroxypropyl Methyl Cellulose (HPMC)– Grades E5 & E15

Product Summary

Hydroxypropyl Methyl Cellulose (HPMC), CAS No. 9004-65-3, is a semi-synthetic, water-soluble polymer made from 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.

Trick Requirements

Chemical Call: Hydroxypropyl Methyl Cellulose
CAS Number: 9004-65-3
Methoxy Content: 19%– 30%.
Hydroxypropoxy Web content: 4%– 32%.
pH (2% service): 4.0– 8.0.
Loss on Drying: ≤ 5.0%.
Ash Content: ≤ 1.5%.

The E5 quality has a reduced viscosity, generally around 5 mPa · s in a 2 % liquid option at 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 (typically 50– 70 ° C).

Applications

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

Storage space & Handling

Shop HPMC in a trendy, dry area away from wetness. Maintain containers firmly closed. Usage conventional commercial health practices when managing. Stay clear of breathing of dust and contact with eyes or skin.

Applications of Hydroxypropyl Methyl Cellulose (HPMC) E5 and E15

What Is HPMC?

Hydroxypropyl methyl cellulose (HPMC), with CAS number 9004-65-3, is a plant-based polymer widely used in food, drugs, and cosmetics. Qualities E5 and E15 are common in markets that need risk-free, reliable active ingredients.

Use in Food Products

In food, 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

In creams, creams, and hair shampoos, HPMC provides a rich, smooth feeling. It holds water well, 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.
