5 Things to Know Before Buying Hydroxy Ethyl Methyl Cellulose

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?

1. Product specifications: Different product applications require different qualities of hydroxyethyl cellulose. Before purchasing, it is necessary to clarify the viscosity, solid content, application range and other indicators of the required products to ensure that the selected product meets the requirements of use.
2. Manufacturer’s reputation: choosing a manufacturer with a good reputation can ensure the quality of the product and the stability of supply. You can learn about the manufacturer’s operation by searching the internet, consulting with industry experts, checking social media, and so on.
3. Price and cost-effectiveness: The price of hydroxyethyl cellulose varies depending on cost, specification, quality, brand and other factors. When purchasing, you should choose a reasonably priced product while ensuring quality.
4. After-sales service: Understand the manufacturer’s after-sales service policy, such as product return, technical support, etc., to ensure that problems encountered in the process of use can be resolved in a timely manner. If you have questions about the product, be sure to ask the supplier for clarification before you buy.

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.
