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:
- 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.
- In food processing HEMC can also be used as adhesive, emulsifier,
film forming agent, thickener, suspending agent, dispersant and
water retaining agent.
- In chemical industry HEMC is used as adhesive of toothpaste,
cosmetics, detergents etc.
- 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.
- 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.
