- Hydroxypropyl Methylcellulose (HPMC) is a cellulose derivative that is commonly used in a variety of industries due to its unique properties and versatility. This article aims to explore the characteristics, applications, and benefits of HPMC.
- In the cosmetics industry, HEC is a popular choice for its non-toxic and non-irritating nature
- In recent years, the demand for redispersible polymer powder has been on the rise, leading to fluctuations in its price in the market. Redispersible polymer powder is a free-flowing white powder that can be easily dispersed in water to form a stable emulsion. It is widely used in the construction industry as an additive in dry mix mortar formulations to improve the properties of the mortar.
I haven’t found a single loaf of bread, roll or sandwich thin that doesn’t now contain this additive.
- In the pharmaceutical industry, HPMC is used as a coating agent for tablets and capsules. It provides a protective barrier for the drug against moisture, oxygen, and other external factors, ensuring its stability and effectiveness. HPMC is also used as a controlled-release agent, allowing the drug to be released slowly in the body, leading to better absorption and prolonged action. Additionally, HPMC is used as a binder in tablets, improving their mechanical strength and disintegration properties
hydroxy methyl propyl cellulose. Hydroxypropyl methylcellulose, often abbreviated to HPMC or also called hypromellose, is a chemical compound widely used as an aid in pharmaceutical and food products. HPMC is a type of cellulose ether, a derivative of natural cellulose, which is extracted from plant sources such as wood pulp or cotton fibers. This compound is specifically valued for its ability to serve as a thickener, stabilizer, emulsifier and film former. It has many functions.
- In the pharmaceutical sector, HPMC plays a crucial role as an excipient. It is used as a binder in tablet formulations, ensuring that the active ingredients adhere together during the manufacturing process. Additionally, HPMC is employed as a coating material for tablets and capsules, providing a protective layer that enhances their shelf-life and masks any unpleasant tastes. Furthermore, its non-toxicity and inertness make it safe for use in drug delivery systems.
- The science behind liquid thickeners lies in their ability to form colloidal dispersions or gels when mixed with liquids. The molecules in these substances either absorb water, forming a gel matrix, or associate with each other to increase viscosity. The choice of thickener depends on factors such as the desired final texture, the temperature sensitivity of the product, and any dietary restrictions.
HPMC stands for hydroxypropyl methylcellulose or hypromellose for short. HPMC is the material from which most supplement capsules are made. It is a clear, tasteless, vegetarian and vegan appropriate material. It is normally made by extraction from wood pulp.
- On the other hand, Low Viscosity grades like HPMC E3 and E5 are more suited for applications where rapid hydration and low viscosity are desired. They are frequently used in the food industry as emulsifiers and stabilizers, enhancing product texture and stability. In the paint and coating industry, they enhance flow properties and provide a smooth finish.
- The Role of HPMC in Building Coatings and Adhesives
- higher DS and MW will result in a slower release rate and increased viscosity,


4. HPMC VS HEC : Dispersion
hpmc for wall putty. This makes it an excellent choice for use in both interior and exterior applications, as it can withstand various weather conditions and humidity levels without compromising its performance.
Genotoxicity studies also indicate that HPMC is not mutagenic or genotoxic. Carcinogenicity studies have shown no evidence of potential carcinogenicity in animals treated with HPMC.
