Introduction to Hydroxypropyl Methyl Cellulose HPMC EP USP 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 EP USP 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)– EP/USP Grade
Pharmaceutical Uses
Hydroxypropyl methyl cellulose (HPMC) is widely used in the pharmaceutical sector. It satisfies stringent top quality standards established by the European Pharmacopoeia (EP) and USA Pharmacopeia (USP). This makes it secure for usage in medicines. HPMC functions as a binder, thickener, and film-forming representative in tablet computers and capsules. It aids control how rapid a medication dissolves in the body. This makes sure the medicine works correctly and securely. It likewise acts as an eye lubricating substance in synthetic tears, supplying relief from completely dry eyes.
Food Market Applications
In food production, HPMC works as a stabilizer and emulsifier. It keeps components mixed well and stops splitting up. You can discover it in low-fat or fat-free items to boost texture. It likewise helps baked items stay soft longer. Because it is safe and authorized for consumption, it prevails in many refined foods.
Construction and Structure Products
HPMC plays a crucial role in construction chemicals. It boosts workability and water retention in cement-based products like floor tile adhesives, plasters, and self-leveling substances. Better water retention means stronger bonding and less fractures. It additionally makes blending much easier and provides workers more time to apply the material prior to it sets.
