Hydroxyethyl Methyl Cellulose （MHEC） are water soluble nonionic cellulose ethers, which are offered as free flowing powder or in granular form cellulose. Hydroxyethyl Methyl Cellulose （MHEC） is made from highly pure cotton-cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents. HEC appears to be white powder and is odorless and tasteless. It is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water MHEC will swell into colloidal solution and its solubility is not influenced by PH value. Similar to methyl cellulose while being added to Hydroxyethyl groups. MHEC is more resistant to saline, easily soluble in water and has higher gel temperature. MHEC is also known as HEMC, Methyl Hydroxyethyl Cellulose, which can be used as highly efficient water retention agent, stabilizer, adhesives and film-forming agent in construction, tile adhesives, cement and gypsum-based plasters, liquid detergent, and many other applications.
