Hydroxyethyl cellulose ether

WeKcelo HEC ---- Hydroxyethyl Cellulose Hydroxyethyl Cellulose is a nonionic cellulose derivative that dissolves readily in water, either cold or hot.
It is used to prod
uce solutions having a wide range of viscosity. Such solutions has typical Non-Newtonian flow characteristic.
WeKcelo HEC has unique combination of water  . Water solution is smooth , homogenous solution , and good flow and leveling.

An idealized structural formula of WeKcelo HEC is shown .

The three hydroxyl groups of each of the anhydroglucose units of the cellulose are activated with sodium hydroxide.

Subsequently these groups are etherified with ethylene oxide to form the hydroxyethyl ether of cellulose. Ethylene oxide,

reacting at previously substituted hydroxyl groups, can polymerize to form a side chain.
