Introduction to Chemical raw material HPMC Hydroxypropyl Methyl Cellulose 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, medicine, and food.

Characteristics and advantages of Chemical raw material HPMC Hydroxypropyl Methyl Cellulose 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.

Item Review

Hydroxypropyl Methyl Cellulose (HPMC) is a white to off-white, free-flowing powder. It is unsmelling and safe. This cellulose ether dissolves quickly in cold water to create a clear, viscous solution. HPMC does not dissolve in hot water, alcohol, or many natural solvents.

Trick Qualities

HPMC offers superb water retention, enlarging, and film-forming capacities. It remains steady across a large pH variety (generally 3– 11). The product reveals great compatibility with numerous various other ingredients made use of in commercial and customer solutions. Its viscosity can be readjusted based upon the quality selected, making it ideal for various applications.

Typical Applications

In the building industry, HPMC is widely made use of in cement-based products like floor tile adhesives, makes, and self-leveling substances. It enhances workability and prevents water loss during curing. In the pharmaceutical field, HPMC acts as a binder, finishing agent, or controlled-release matrix in tablets. It is additionally accepted for usage in food as a stabilizer or thickener (E number E464). Individual care items such as shampoos, lotions, and toothpastes often consist of HPMC to boost structure and stability.

Applications of Chemical raw material HPMC Hydroxypropyl Methyl Cellulose CAS 9004-65-3

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

Construction and Structure Materials

HPMC is extensively made use of in construction products like ceramic tile adhesives, self-leveling compounds, and exterior insulation systems. It aids maintain water in cement-based mixtures. This enhances workability and offers employees even more time to apply the product uniformly. It additionally prevents sagging on vertical surfaces and boosts bond toughness.

Pharmaceuticals

In the drug market, HPMC acts as a binder, thickener, and controlled-release agent. It is risk-free for human use and dissolves easily in cool water. Lots of tablets utilize it to manage exactly how fast the medicine releases in the body. It also maintains fluid medicines and eye stop by boosting thickness without inflammation.

Food Industry

HPMC functions as a food additive under code E464. It works as a thickener, emulsifier, and foam stabilizer. You can locate it in gluten-free baked items, where it changes the binding function of gluten. It likewise aids keep moisture in processed foods and improves appearance in sauces and dressings.

Paints and Coatings

Paint makers include HPMC to water-based paints to boost uniformity and application. It stops pigments from settling and makes the paint much easier to spread out. The film created after drying out stays smooth and resists breaking.

Personal Care Products

Tooth pastes, hair shampoos, and creams commonly consist of HPMC. It gives these products an abundant, creamy feeling and helps energetic components stay combined. It additionally creates a mild protective layer on skin or hair without obstructing pores.
