Conclusion
The backbone of HEC is based on cellulose, which consists of repeated glucose units linked by beta-1,4-glycosidic bonds. In its natural form, cellulose is crystalline and insoluble in water. However, through the process of etherification, where ethylene oxide is reacted with the hydroxyl groups on the cellulose polymer, HEC is created. This modification results in the introduction of hydroxyethyl groups (-CH2CH2OH) into the cellulose structure. The presence of these hydroxyethyl groups distinguishes HEC from unmodified cellulose, enhancing its solubility in aqueous environments.
