Product details

Introduction:
Our product HEMC is made from highly pure cotton - cellulose by reaction of etherification under alkaline conditions without any organs of animals, fat and other bioactive constituents.

Physical properties:
HEMC appears to be white granule or powder and is odorless and tasteless. It is featured by hygroscopicity and hardly soluble in hot water, acetone, ethanol and toluene. In cold water HEMC will swell into colloidal solution and its solubility is not influenced by PH value. Similar to methyl cellulose while being added to hydroxyethyl groups, HEMC is more resistant to saline, easily soluble in water and has higher gel temperature.

Usages:

  1. In pharmacy HEMC can be used as hydrophilic gel - matrix material for making preparation s of sustained - release formulations, pore - causing agent and coating agent and also thickener, suspending agent, dispersant, adhesive, emulsifier, film forming agent and water retaining agent.
  2. In food processing HEMC can also be used as adhesive, emulsifier, film forming agent, thickener, suspending agent, dispersant and water retaining agent.
  3. In chemical industry HEMC is used as adhesive of toothpaste, cosmetics, detergents etc.
  4. HEMC is a kind of good admixture of the powder building materials for it can be used as gelling agent and water retaining agent of cement, gypsum and lime.
  5. Hydroxyethyl methyl cellulose (HEMC) is widely used in waterborne latex paint, construction and building material, printing ink, oil drilling etc to play a role of thickening, retaining water and improving constructability. It is very suitable for dry and wet mortar series products.
