Hydroxyethyl methyl cellulose HEMC is a white powder. It is tasteless and non-toxic. It can be dissolved in cold water to form a transparent viscous solution. It has the characteristics of thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, water retention and colloid protection. Hydroxyethyl methyl cellulose aqueous solution has good hydrophilicity and is an efficient water retention agent. Because it contains hydroxyethyl groups, it has good mildew resistance, good viscosity stability and mildew resistance during long-term storage.

1. It can be used as cementing agent and water-retaining agent of cement, gypsum and lime. It is an excellent admixture for powder building materials.
2. In food processing, it can be used as adhesive, emulsification, film forming, thickening, suspending, dispersing, water retaining agent and so on.
3. In the daily chemical industry, it is used as an additive for toothpaste, cosmetics, detergents, etc.
4. In the pharmaceutical, as the preparation of sustained-release preparation of hydrophilic gel skeleton material, pore-forming agent, coating agent. It can also be used as thickening, suspension, dispersion, adhesion, emulsification, film-forming, water retention agent.
Hydroxyethyl methyl cellulose is a polymer powder with hygroscopicity and water absorption. Its storage and transportation process should be in the form of original packaging, and keep cool and dry. In the process of production and use, once the original packaging is opened, re-sealing measures should be taken to avoid the invasion of water.
