Introduction to Hydroxypropyl Methyl Cellulose HPMC Powder 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 Powder 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.

Applications of Hydroxypropyl Methyl Cellulose (HPMC) Powder

Construction and Building Materials

HPMC powder is commonly used in building. It enhances workability in cement-based items like tile adhesives, plasters, and self-leveling substances. The powder aids keep water, which allows cement to moisten appropriately. This causes stronger bonds and less splits. HPMC additionally provides better slip resistance and open time for installers.

Pharmaceuticals

In the medicine market, HPMC acts as a binder, covering representative, or controlled-release matrix. It is risk-free for human usage and liquifies gradually in the body. Tablet computers with HPMC launch energetic ingredients in time, which aids maintain stable drug degrees. The powder is likewise utilized in eye goes down to offer lubrication and comfort.

Food Market

Hydroxypropyl methyl cellulose acts as a thickener, emulsifier, and stabilizer in several food. It maintains ingredients mixed equally and boosts appearance. You can find it in sauces, gelato, and gluten-free baked products. HPMC is approved as a preservative and lugs the E number E464.

Paints and Coatings

Paint manufacturers add HPMC powder to water-based paints. It improves viscosity and prevents pigments from resolving. The outcome is smoother application and much better protection on wall surfaces. HPMC likewise reduces splattering throughout cleaning or rolling.

Cosmetics and Personal Care

In creams, shampoos, and lotions, HPMC works as a film-former and thickening representative. It gives items an abundant feeling without greasiness. The powder is stable throughout a wide pH variety and mixes well with various other typical active ingredients.

HPMC powder (CAS 9004-65-3) is valued for its versatility, safety and security, and efficiency across lots of sectors. Its capacity to liquify in chilly water, type clear movies, and remain secure under warmth makes it a trusted choice for formulators worldwide.
