HPMC E15 is a hydroxypropyl methylcellulose with medium viscosity. 

Basic Information

• Chemical Name: 2 - Hydroxypropyl methylcellulose.

• Appearance: It is a white or off - white fibrous or granular powder.

• Solubility: It is almost insoluble in anhydrous ethanol, ether, or acetone, and swells in cold water to form a clear or slightly turbid colloidal solution.

Performance Characteristics

• Viscosity Characteristics: The viscosity of its 2% aqueous solution at 20℃ is usually between 12 - 18mPa·s. It belongs to the medium - viscosity level and can provide moderate thickening and stabilizing effects in different applications.

• Film - forming Property: It has good film - forming properties. The formed film has good transparency and high toughness, and is not easy to adhere during production.

• Stability: It has good chemical stability and can maintain good performance in acid - base environments. For drugs that are easy to absorb moisture and are unstable, using it as an isolation layer can improve the stability of drugs.

Application Areas

• Pharmaceutical Field: It can be used as a coating material for drugs, which can cover up the bad smell of drugs, improve the compressive strength of drugs and reduce brittleness. It can also be used as an excipient for sustained - release tablets to regulate the drug release rate.

• Construction Field: It is suitable for the preparation of tile adhesives, water - based coatings, cement mortars, etc., which can improve the construction performance, water - retention property and bonding strength of these materials.

• Other Fields: In the cosmetic industry, it can be used as a thickener and stabilizer, which helps to improve the texture and stability of products and is used in products such as lotions and creams. In the food industry, it can also be used as a thickener, emulsifier or stabilizer in the processing of foods such as dairy products, fruit juices and sauces.
