Methyl Hydroxyethyl Cellulose: A Comprehensive Review of Properties and Applications

Views: 0     Author: Site Editor     Publish Time: 2023-09-04      Origin: Site


Methyl hydroxyethyl cellulose, commonly abbreviated as MHEC, is a cellulose ether with both methyl and hydroxyethyl substituents. MHEC has been widely used in various industries due to its unique properties, such as high water retention capacity, good thickening ability, and excellent film-forming properties. In this review, we will discuss the properties, applications, and potential future developments of MHEC.


MHEC is a non-ionic water-soluble polymer with a chemical structure similar to cellulosic compounds. The hydroxyethyl and methyl groups covalently bound to the cellulose backbone of MHEC provide the polymer with improved solubility, stability, and compatibility with other synthetic and natural polymers.

MHEC is soluble in water and other polar solvents. Depending on the degree of substitution of the hydroxyethyl and methyl groups, MHEC can exhibit different solubility behavior and viscosity. The viscosity of MHEC solutions is influenced by several factors such as concentration, shear rate, temperature, and pH.

MHEC has high water retention properties, which makes it an ideal additive for applications that require water retention characteristics. The hydrophilic hydroxyethyl group retains water, which provides a source of moisture and prevents the material from drying out.


Building and Construction Industry

MHEC has been extensively used in the building and construction industry due to its superior binding, thickening, and water retention properties. The most common applications of MHEC in this industry include tile adhesives, grouts, and cement-based mortars.

MHEC acts as an efficient thickener in tile adhesives, enhancing the consistency of the product and reducing water separation. In cement-based mortars, MHEC improves the water retention capability, reducing the occurrence of cracking and improving the adhesive properties.

Pharmaceutical Industry

MHEC has also been applied in the pharmaceutical industry as a binder, emulsifier, and thickener in tablets, creams, and ointments. In tablet formulations, MHEC improves the binding properties of the active pharmaceutical ingredients, and enhances the disintegration time and dissolution rate of tablets.

MHEC is also used in topical creams and ointments as an emulsifier and thickener. The high water-retention properties of MHEC ensure that the skin stays moisturized, while its thickening ability helps to provide a uniform and stable consistency.

Food Industry

In the food industry, MHEC has been used as a thickener, stabilizer, texture modifier, and gelling agent in several products such as sauces, dressings, and baked goods. MHEC enhances the texture, consistency, and shelf-life of food products, while also contributing to their overall sensory quality.

Paints and Coatings Industry

MHEC has been applied in the paints and coatings industry as a thickener, film-forming, and stabilizing agent. MHEC enhances the rheological properties of paints and coatings, improving flow, leveling, and film-forming characteristics.

Future Developments

Despite the widespread use of MHEC in various industries, further research is needed to continue to improve its properties and expand its applications. Potential future developments may include:

• Optimization of the structure of MHEC, by modifying its chemical composition and molecular weight, to achieve better performance in specific applications.

• New technologies to improve the solubility and viscosity of MHEC, such as the implementation of nanotechnology and green chemistry.

• The development of MHEC-based products with new functionalities, such as self-healing properties, antimicrobial activity, and optical properties.


Methyl hydroxyethyl cellulose is a versatile polymer with a wide range of applications in various industries. Its unique properties such as high water retention capacity, good thickening ability, and excellent film-forming properties have made it a valuable additive in many industrial applications. Future developments such as optimization of the chemical structure of MHEC, new technologies to improve its properties, and development of MHEC-based products with new functionalities will further enhance its performance and expand its applications.
