Uses:

1. In pharmaceuticals, it is used as a hydrophilic gel skeleton material, porogen, and coating agent for the preparation of sustained-release preparations. also available as a preparation

Thickening, suspending, dispersing, binding, emulsifying, film-forming, water-retaining agent.

2. Food processing can also be used as, adhesive, emulsifying, film-forming, thickening, suspending, dispersing, water-retaining agent, etc.

3. In the daily chemical industry, it is used as an additive in toothpaste, cosmetics, detergents, etc.

4. Used as gelling agent for cement, gypsum and lime, water-retaining agent, and excellent admixture for powder building materials.

5. Hydroxyethyl methyl cellulose is widely used as an excipient in pharmaceutical preparations, including oral tablets, suspensions and topical preparations.

6. Hydroxyethyl methyl cellulose (HEMC) is prepared by introducing ethylene oxide substituents (MS0.3~0.4) into methyl cellulose (MC), and its salt resistance is better than that of unmodified polymers. The glue temperature is also higher than MC. Hydroxyethyl methyl cellulose (HEMC) is widely used in water-based latex coatings, building construction and building materials, printing inks, oil drilling, etc., to thicken and retain water, improve workability, and is used in dry and wet mortar products.

It is similar to the property of methyl cellulose, but due to the presence of hydroxyethyl group, Hydroxyethyl methyl cellulose is more soluble in water, the solution is more compatible with salt, and has a higher condensation temperature.
