HEMC
Hydroxyethyl methylcellulose (HEMC) is widely used in water-based latex coatings, construction and building materials, printing inks, oil drilling, etc. It plays a thickening and water-retaining role, improves workability, and is used in dry and wet mortar series products.
Hydroxyethylmethylcellulose is widely used as an excipient in pharmaceutical preparations, including oral tablets, suspensions and topical preparations.
1.Main application
-
Pharmaceuticals are used as hydrophilic gel matrix materials, porogens, and coating agents for preparing sustained-release preparations. It can also be used as thickening, suspending, dispersing, bonding, emulsifying, film-forming and water-retaining agent for preparations.
-
In food processing, it can also be used as a binding, emulsifying, film-forming, thickening, suspending, dispersing, water-retaining agent, etc.
-
In the daily chemical industry, it is used as an additive in toothpaste, cosmetics, detergents, etc.
-
It is used as a gelling agent and water retaining agent for cement, gypsum and lime, and is an excellent additive for powder building materials.
- Hydroxyethylmethylcellulose is widely used as an excipient in pharmaceutical preparations, including oral tablets, suspensions and topical preparations.
