Methyl Hydroxyethyl Cellulose (MHEC) is a widely used cellulose derivative with good thickening, water retention, film-forming and stabilizing effects. It is mainly used in many industries such as building materials, coatings, ceramics, medicine and cosmetics.
1. Construction Industry
In the construction industry, methyl hydroxyethyl cellulose (MHEC) is an important additive and is widely used in cement-based and gypsum-based materials such as mortar, putty powder and tile adhesives. These building materials need to have good construction performance, water retention, adhesion and durability, and MHEC improves these properties through its excellent physical and chemical properties.
Application in mortar: MHEC can effectively improve the workability and fluidity of mortar and enhance the bonding properties of the material. Due to its good water retention, it can ensure that the mortar maintains appropriate humidity during construction, thereby improving the strength and durability of the mortar.
Application in tile adhesives: In tile adhesives, MHEC can improve the adhesion of the material, so that the tiles have a better bonding effect in both dry and wet environments. In addition, the excellent water retention provided by MHEC can also reduce the shrinkage of adhesives and prevent cracks.
Application in putty powder: In putty powder, MHEC can effectively improve the ductility, smoothness and crack resistance of the product, ensuring the uniformity and durability of the putty layer.
2. Paint industry
Methyl hydroxyethyl cellulose is commonly used in architectural paints and decorative paints as a thickener, suspending agent and stabilizer.
Thickener: MHEC plays a thickening role in water-based paints, helping to control the viscosity of the paint, thereby ensuring that the paint can be evenly applied and avoid sagging during construction.
Film former: It has good film-forming properties, allowing the coating to form a uniform film with good adhesion and durability.
Suspending agent and stabilizer: MHEC can also prevent the precipitation of pigments and fillers during storage or construction, ensuring the long-term stability and consistency of the paint.
3. Ceramic industry
In the ceramic industry, MHEC is mainly used as a binder and thickener. During the production process, ceramics need to have a certain viscosity and fluidity to ensure the smooth progress of the molding process.
Binder: MHEC can enhance the bonding force of the ceramic body during molding, making it easier to mold and reducing deformation or cracking during drying and sintering.
Thickener: MHEC can adjust the viscosity of the ceramic slurry, ensure its fluidity in different processing techniques, and adapt to various molding processes, such as grouting, rolling and extrusion molding.
4. Pharmaceutical Industry
Methyl hydroxyethyl cellulose, as a non-toxic and non-irritating polymer compound, is also widely used in the pharmaceutical field, especially in pharmaceutical preparations.
Film-forming material for tablets: MHEC is used as a film coating material for pharmaceutical tablets. It can form a uniform, transparent protective film, delay drug release, improve the taste of drugs, and improve the stability of drugs.
Binder: It is also used as a binder in tablets, which can increase the bonding force of tablets, ensure the uniform distribution of drug ingredients in tablets, and prevent tablets from breaking or disintegrating.
Stabilizer in drug suspension: MHEC is also used in drug suspension to help suspend solid particles, prevent precipitation, and ensure the stability and uniformity of the drug.
5. Cosmetic industry
Due to its safety and stability, MHEC is widely used in cosmetics such as skin care products, shampoo, toothpaste and eye shadow as a thickener, moisturizer and film former in the cosmetics industry.
Application in skin care products and shampoo: MHEC plays a thickening and moisturizing role in skin care products and shampoo by enhancing the viscosity and stability of the product, increasing the product’s smearing feel, extending the moisturizing time, and also improving the product’s texture and ductility.
Application in toothpaste: MHEC plays a thickening and moisturizing role in toothpaste, ensuring the stability and smoothness of the paste, making the toothpaste not easy to deform when extruded, and can be evenly distributed on the tooth surface when used.
6. Food industry
Although MHEC is mainly used in non-food fields, due to its non-toxicity and safety, MHEC is also used in small amounts as a thickener and stabilizer in some special food processing processes.
Food packaging film: In the food industry, MHEC is mainly used to make degradable food packaging film. Due to its good film-forming property and stability, it can provide good protection for food, while being environmentally friendly and degradable.
7. Other applications
MHEC also has some special applications in other industries, such as paints, inks, textiles, electronics and other fields, mainly used as thickeners, stabilizers, suspending agents and adhesives.
Paints and inks: MHEC is used as a thickener in paints and inks to ensure that they have appropriate viscosity and fluidity, while enhancing film-forming property and gloss.
Textile industry: In textile printing and dyeing processes, MHEC is used to increase the viscosity of slurry and improve the printing and dyeing effect and wrinkle resistance of fabrics.
Methyl hydroxyethyl cellulose (MHEC), as an important cellulose ether, has been widely used in many fields such as construction, coatings, ceramics, medicine, cosmetics, etc. due to its excellent thickening, water retention, film-forming and stabilizing properties. Its versatility makes it an indispensable additive in modern industrial production. In the future, with the advancement of technology and the increase in demand, MHEC will show greater potential in more fields.
