Product Description

Hydroxyethyl Methyl Cellulose (HEMC)

Hydroxyethyl Methyl Cellulose (HEMC) is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing. It's odorless, tasteless and non-toxic white powder, can be dissolved in cold water to form a transparent viscous solution with the properties of thickening, binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection.

It is readily soluble in cold water to form a transparent and viscous solution, and is suitable for various construction scenarios. It has stable performance, excellent salt and mold resistance, and is not prone to deterioration during long-term storage. The core functions include excellent water retention, thickening and emulsifying dispersion properties. It can delay water evaporation, enhance system stability, and form flexible films, optimizing the smoothness of construction and the forming effect of materials. It is a high-quality multi-functional additive for the building materials, daily chemical and other fields.

Application fields of HEMC

HEMC (hydroxyethyl methylcellulose) has a wide range of applications, with a core focus on industries such as building materials, daily chemicals, and coatings. In the field of building materials, it is a key additive for putty powder, mortar and self-leveling materials. It optimizes workability through strong water retention and thickening, prevents cracking, and enhances bonding strength and flatness. In latex paint, texture paint and other coatings, it can stabilize the system, prevent pigment sedimentation, enhance anti-sagging property and construction smoothness.
In the daily chemical industry, it is often used in products such as shampoos, face creams, and toothpaste to thicken and stabilize, enhancing the touch feel and formula stability during use.

Product production process

HEMC is produced from refined cotton through an alkaline etherification process. Firstly, the refined cotton is crushed and then mixed with sodium hydroxide solution for low-temperature soaking and stirring to form alkaline cellulose for activation. Then, two etherifying agents, chloromethane and propylene oxide, were added to the activated alkali cellulose. Under certain temperature and pressure, the reaction was stirred to generate crude HPMC. Finally, the crude product is neutralized with hydrochloric acid, washed with hot water or organic solvents to remove impurities, and then dried, crushed, screened and packaged as the finished product.
