Hydroxyethyl methylcellulose (HEMC) is a non-ionic cellulose ether made from natural polymer material cellulose through a series of etherification. It is an odorless, tasteless, non-toxic white powder Or particles, can be dissolved in hot and cold water to form a transparent viscous solution, insoluble in general organic solvents, and the dissolution is not affected by the pH value. It has thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, surface active, moisture-retaining and salt-resistant properties.
