Product Details

Hydroxyethyl methyl cellulose is a odorless, odorless, non-toxic white powder that 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.  Aqueous solutions can be used as colloidal protectants, emulsifiers and dispersants due to their surface active properties.  Hydroxyethyl methyl cellulose aqueous solution has good hydrophilicity, which is a highly efficient water-retaining agent.

HEMC Main application

Hydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose mixed ether made from cotton and wood through alkalization, ethylene oxide and methyl chloride etherification. HEMC is widely used in water-based latex coatings, construction and building materials, printing ink, oil drilling and other fields. Its properties are similar to HPMC, but the presence of hydroxyethyl makes HEMC more soluble in water, the solution is more compatible with salt, and has a higher condensation temperature.

1. in the pharmaceutical field, hydrophilic gel framework materials and pharmaceutical excipients for the preparation of sustained-release preparations are widely used, including oral tablets, suspensions, local preparations, porogens and coating agents.

2. in the field of food processing, it is used for bonding, emulsification, film-forming, thickening, suspension aid, dispersion, water retaining agent, etc.

3. in the field of daily chemical industry, it is used as an additive for toothpaste, cosmetics, detergent, etc.

4. in the field of building materials, it is used as a gelling agent and water retaining agent for cement, gypsum and lime, and is an excellent admixture for powder building materials.
