Is hypromellose the same as HPMC?

Yes, hypromellose is the same as HPMC (hydroxypropyl methylcellulose). Hypromellose is the international non-proprietary name (INN) for this material, while HPMC is the common trade name used in the industry.

HPMC is a modified cellulose, where some of the hydroxyl groups on the cellulose molecule have been replaced with hydroxypropyl and methyl groups. It is a white or off-white, odorless, and tasteless powder that is soluble in water and organic solvents.

HPMC is commonly used as a thickener, binder, and emulsifier in a variety of applications, including pharmaceuticals, foods, cosmetics, and personal care products. Its properties, such as viscosity, solubility, and gelation, can be adjusted by varying the degree of substitution (DS) and the molecular weight (MW) of the polymer.

The use of hypromellose in pharmaceuticals is particularly widespread due to its versatility and biocompatibility. It is commonly used as a tablet binder, disintegrant, and sustained-release agent, as well as a thickener and suspending agent in liquid formulations. Its ability to form a gel at higher concentrations also makes it useful in controlled-release applications.

Hypromellose is also used in other industries. For example, it can be used as a thickener, stabilizer, and emulsifier in food products, such as sauces, dressings, and dairy products. In personal care products, hypromellose can be used as a thickener and emulsifier in lotions, shampoos, and other cosmetic formulations.

hypromellose and HPMC refer to the same material, which is a versatile and widely used polymer in various industries. Its properties and functionality can be adjusted based on the specific application and desired end product.
