Hydroxypropyl Methylcellulose, An Overview

What Is Hydroxypropyl Methylcellulose?

HPMC is a cellulose ether that, on average, has both high tensile strength and viscosity. It is often used as a thickener and emulsifier, as it quickly disperses in water. It is also soluble in most organic solvents and is generally nontoxic.

It is a semisynthetic, inactive, viscoelastic polymer commonly used as a lubricant in ophthalmology, or as an excipient or vehicle in oral medicines.

In addition, it is used as a thickener, stabilizer, emulsifier, film-forming agent, etc. in the production of other petrochemicals, coatings, building materials, paint removers, papermaking, cosmetics and other products. Here we will detail more about the applications of Hydroxypropyl Methyl cellulose:

√ Hydroxypropyl methylcellulose in skin care

Methyl hydroxyethyl cellulose is found in many cosmetic products, including hair sprays, shampoos, conditioners, toothpaste, and soaps. Like other uses for methyl hydroxyethyl cellulose, it's used to increase the viscosity of these products and make them easier to apply.

√ As a kind of thickeners

Clindamycin Phosphate Gel is a clear, colorless to pale yellow liquid that is thickened with hydroxypropyl methylcellulose. It is applied to the skin once or twice a day…

Properties and Applications

The chemical formula of HPMC is C56H108O30 and it is produced on an industrial level by treating cellulose, propylene, and methylene with sodium hydroxide by the process of alkalization and etherification. HPMC has well-diversified applications across various sectors. It is used in pharmaceuticals, ceramics, adhesives, paints & coatings, buildings, and personal care products. It is used in construction materials as a tile binder, water retention agent and rheology modifier. It also serves as an alternative to gelatin because of its physical similarities to gelatin and its vegetarian source.
