Introduction to Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Hydroxypropyl Methylcellulose (HPMC), whose Chinese name is hydroxypropyl methylcellulose, is a semi-synthetic, non-ionic cellulose ether obtained by chemically modifying natural cellulose. This white powder can form a transparent viscous solution after dissolving in water. It has excellent thickening, water retention, stability and film-forming properties. It is an indispensable multifunctional additive in many fields such as construction.

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

Excellent water solubility: It can be quickly dissolved in cold water to form a clear and stable solution.

Efficient thickening and water retention ability: Increase the viscosity of the material, effectively reduce water evaporation, and improve work efficiency.

Good stability: It has good stability to acids, alkalis, and salts, and is suitable for a wide range of pH values.

Film-forming and protective effects: After drying, it forms a tough and transparent film to protect the substrate and prevent water penetration and evaporation.

Non-toxic and non-irritating: It has good biocompatibility and is suitable for the fields of medicine and food.

Adjustability: By changing the degree of substitution and molecular weight, its performance can be adjusted to meet different application requirements.

Trick Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies easily in chilly water yet does not dissolve in hot water over its gelation temperature level. The product creates clear, anemic services with excellent film-forming ability.

Typical viscosity varieties from 5 mPa · s to 100,000 mPa · s (determined at 2% concentration, 20 ° C), relying on the grade. Wetness content stays below 5% (by weight). The pH of a 2% remedy normally falls in between 4.0 and 8.0.

Pureness and Top Quality Standards

This HPMC fulfills pharmacopeial criteria such as USP-NF, EP, and JP when made use of in pharmaceutical applications. For industrial or building uses, it complies with appropriate technological requirements. Hefty metals are kept under 10 ppm. Residue on ignition stays below 1.5%. Microbial limits comply with basic guidelines: overall cardio count ≤ 100 CFU/g, yeast and mold and mildew ≤ 10 CFU/g, and absence of E. coli and Salmonella.

Storage and Handling

Shop HPMC in a great, dry place away from direct sunshine. Keep containers firmly near protect against wetness absorption. Use basic commercial health techniques when handling. Prevent creating dirt.

Common Applications

HPMC is commonly made use of in pharmaceuticals as a binder, thickener, or controlled-release agent in tablets. In building, it boosts workability and water retention in cement-based items like tile adhesives and provides. It also serves as a stabilizer in food, cosmetics, and paints.

Applications of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Applications of Hydroxypropyl Methyl Cellulose (HPMC) CAS 9004-65-3

Construction and Building Materials

HPMC is commonly used in dry-mix mortars, ceramic tile adhesives, and self-leveling compounds. It boosts water retention so cement can completely hydrate. This leads to more powerful bonds and much better workability. Builders also depend on HPMC to reduce drooping and prolong open time throughout application.

Drugs

In tablets and pills, HPMC function as a binder, film-coating agent, or controlled-release matrix. It liquifies gradually in the digestive tract, aiding active ingredients launch at the appropriate rate. Because it is non-toxic and steady, regulative companies approve it for dental use worldwide.

Food Market

HPMC acts as a thickener, emulsifier, and stabilizer in numerous refined foods. You can locate it in sauces, ice cream, and gluten-free baked products. It helps keep appearance and avoids separation without changing taste.

Personal Treatment and Cosmetics

Shampoos, lotions, and tooth pastes frequently consist of HPMC. It gives products a smooth feel and keeps ingredients equally combined. Its film-forming capacity additionally aids skincare products remain on the skin much longer.

Paints and Coatings

Suppliers add HPMC to water-based paints to control thickness and stop splattering. It increases pigment suspension and makes brushing easier. The outcome is an uniform do with less brush marks.

Agriculture

In chemical and fertilizer formulations, HPMC works as a carrier and adhesive. It aids active components adhere to plant surfaces and slows down drainage after rain. This increases efficiency and reduces waste.

5 FAQs of Hydroxypropyl Methyl Cellulose HPMC CAS 9004 65 3

Frequently Asked Questions About Hydroxypropyl Methyl Cellulose (HPMC)

What is HPMC?

HPMC stands for Hydroxypropyl Methyl Cellulose. It is a white to off-white powder made from plant cellulose. People use it in many products like medicines, food, and building materials. It dissolves in cold water but not in hot water. This makes it useful for controlling texture and thickness.

Is HPMC safe to use?

Yes, HPMC is safe. Regulatory groups like the FDA and EFSA have approved it for use in food and drugs. It passes through the body without being absorbed. That means it does not cause harm when used as directed. Always follow safety instructions on the product label.

What are common uses of HPMC?

HPMC works as a thickener, binder, and film-former. In construction, it helps tile adhesives and plasters stay smooth and work well. In pharmaceuticals, it coats pills so they dissolve at the right time. In food, it adds texture without changing taste. You can also find it in eye drops and cosmetics.

How should HPMC be stored?

Store HPMC in a cool, dry place. Keep it away from moisture and direct sunlight. Use a tightly closed container to stop clumping. If the powder gets wet, it may lose its quality. Check the expiration date before use.

Can HPMC replace other thickeners?

HPMC can often replace other cellulose-based thickeners like methyl cellulose or carboxymethyl cellulose. But results may vary based on the application. Test small batches first to make sure performance meets your needs. Its unique mix of solubility and stability makes it a strong choice in many cases.
