Chemical Structure of Hypromellose

Hypromellose is a water-soluble polymer that is derived from cellulose. It is made by reacting cellulose with propylene oxide and methyl chloride. The resulting polymer has a molecular weight range of 10,000 to 1,000,000 Daltons, depending on the degree of substitution (DS) and the viscosity grade.

The chemical structure of hypromellose consists of a cellulose backbone with hydroxypropyl and methyl groups attached to the anhydroglucose units. The degree of substitution (DS) refers to the average number of hydroxypropyl and methyl groups per anhydroglucose unit. The DS can range from 0.1 to 2.5, depending on the desired properties of the hypromellose.

Properties of Hypromellose

Hypromellose is a white to off-white powder that is odorless and tasteless. It is soluble in water and many organic solvents, but it is insoluble in most nonpolar solvents. Hypromellose has a high viscosity at low concentrations, which makes it an effective thickener and binder. It also has excellent film-forming properties, which make it useful in the production of coatings and films.

The properties of hypromellose depend on the degree of substitution (DS) and the viscosity grade. Higher DS grades have greater water solubility and lower gelation temperatures, while lower DS grades have higher gelation temperatures and better thermal stability. The viscosity grade determines the thickness of the hypromellose solution and its ability to form gels.

Applications of Hypromellose

Hypromellose is used in a wide range of industries, including food, pharmaceuticals, cosmetics, and construction. In the food industry, hypromellose is used as a thickener, emulsifier, and stabilizer in a variety of products, including ice cream, sauces, and baked goods. In the pharmaceutical industry, hypromellose is used as a binder, film-former, and lubricant in tablets, capsules, and ointments. It is also used as a coating agent in controlled-release formulations.

In the cosmetics industry, hypromellose is used as a thickener, emulsifier, and film-former in lotions, creams, and makeup products. In the construction industry, hypromellose is used as a thickener and binder in cement-based products, such as mortars and grouts.
