What is hydroxyethyl cellulose used for?
Hydroxyethyl cellulose, or HEC for short, is prepared from alkaline cellulose and ethylene oxide (or chloroethanol) by etherification reaction, it is a non-ionic cellulose mixed ether, which is odorless, non-toxic, and presents a white or off-white powder. It can form transparent viscous colloids in an aqueous solution with thickening, suspending, dispersing, emulsifying, film-forming and water-retention properties. Therefore, hydroxyethyl cellulose has a wide range of applications in many fields.
Hydroxyethyl cellulose is a versatile elf. In the construction industry, it is used as a stabilizer for paints, allowing them to spread more evenly on walls. In the oil industry, it is an important part of the drilling mud, stabilizing the well wall and preventing well collapse. In the cosmetic field, it is widely used in emulsions, hairsprays and other products by virtue of its good film-forming and water-retaining properties.
Production Process of Hydroxyethyl Cellulose
The production process of hydroxyethyl cellulose is relatively complex, involving multiple steps such as chemical reaction and physical treatment. In brief, the process mainly includes several steps such as raw material preparation, etherification, neutralization, washing, drying and crushing.
Engineers mainly choose cellulose as the starting raw material, and after pretreatment to get suitable cellulose pulp meal for reaction.
Next, through the etherification reaction, the cellulose pulp meal is etherified with ethylene oxide under the action of an alkaline catalyst to generate hydroxyethyl cellulose.
After completing the etherification reaction, the remaining catalyst and unreacted raw materials are removed by neutralization and washing steps.
After drying and crushing, the final hydroxyethyl cellulose product is obtained. The whole process is rigorous and precise to ensure the quality of the product.
What should I pay attention to when buying hydroxyethyl cellulose?
Outstanding Hydroxyethyl Cellulose Manufacturers in China
Although the development of hydroxyethyl cellulose in China is relatively late, some outstanding enterprises have emerged. These companies have strict quality management systems, relatively advanced production processes and equipment, and rich industry experience. For example, Kemox produces hydroxyethyl cellulose with advanced production technology and strict quality control, which enjoys a good reputation in the market. Kemox attaches great importance to environmental protection and is committed to green and sustainable production methods.

Dear friends, I hope this Guide to Buying Hydroxyethyl Cellulose can help you. To buy hydroxyethyl cellulose, you need to consider the product quality, specifications, product use, supplier reputation, price, technical support and service, and other factors to choose the right product for your needs.
Hydroxypropyl Methyl Cellulose (HPMC) is a non-ionic cellulose ether, white or off-white powder or granule, odorless and flavorless. With the properties of thickening, binding, dispersing, emulsifying, film, suspension, adsorption, gel, surface activity, such as maintaining water and protective colloid.
1.Appearance
From the appearance,it can be divided into two points to determine whether the cellulose ether is good or bad.The first point is the whiteness, although whiteness cannot determine whether it has influence on the use of the product.Mostly good products have good whiteness,and the color is uniform.

The second is the transmittance, observing the transmittance of #HPMC after put HPMC into the water to form a transparent colloid.The higher transparency, the better quality. It means less insoluble substances.
2.Odor
Pure HPMC will not smell ammonia, starch and alcohol, however adulterated HPMC can smell various smells, also can feel more heavy even if it is no smell.
3.Fineness
The fineness of HPMC generally has 80 mesh and 100 mesh, there is 120 less mesh. The finer the better, because the finer the fineness, the better water retention.
4.Specific Gravity
The heavier the specific gravity, the heavier the better. The great specific gravity is generally due to the high content of hydroxypropyl inside, and the higher the content of hydroxypropyl is, the better the water-holding performance will be.
