What Is HPMC Used For?

What is HPMC?

HPMC is a natural polymer derived from wood pulp or refined cotton, which is then hydrolyzed to break down the cellulose into smaller molecules. These molecules are then reacted with propylene oxide and/or ethylene oxide to create a polymer that can be used as a thickener, binder, or film former in various applications. It is extremely versatile because it can be tailored to meet different needs by changing the molecular weight or degree of substitution of the reactants used during its production.

Uses in Construction Industry

HPMC has been used in the construction industry for years due to its ability to provide excellent adhesion and strength when mixed with cement-based materials. It can be added directly to dry mixes like mortar or concrete at low concentrations (usually 0.15–0.3%). When added to these dry mixes, it improves their workability by providing better cohesion and plasticity while also increasing their durability by providing increased strength and resistance to cracking over time. It also reduces water absorption of mortar or concrete which helps protect them from freezing temperatures and other harsh weather conditions. Additionally, HPMC can also be used as an additive in masonry sealers and waterproofing compounds for additional protection against moisture infiltration.

Uses in Pharmaceuticals and Food Production

HPMC is widely used by pharmaceutical companies as an excipient because it provides excellent stability for active ingredients while also helping extend the shelf life of products. Due to its non-toxic nature, it can be safely ingested without any adverse effects on human health. Additionally, HMC has also found use in food production due to its ability to act as an emulsifier that helps keep oils suspended evenly throughout water-based products such as salad dressings or mayonnaise. It also acts as a suspending agent that helps powdered ingredients stay evenly distributed throughout liquid ingredients until they are ready for consumption.

hpmc for pharmaceutical and food


Hydroxypropyl methylcellulose (HPMC) has become increasingly popular over the years due to its versatility and usefulness across multiple industries. It is used for construction projects, such as mortars and concretes, where it provides strong adhesion properties; in food production, it acts as an emulsifier, allowing oils to stay suspended in water-based products evenly; and in the pharmaceutical industry, where HPMC provides excellent stability to active ingredients while helping to extend their shelf lives; HPMC provides a highly effective and superior solution!
