Etherification reaction: Ethylene oxide (EO) is added to the alkalized cellulose and etherification reaction is carried out under the action of a catalyst. This is a key step in the preparation of hydroxyethyl cellulose, which involves introducing ether bonds to alter the properties of cellulose. During the reaction process, it is necessary to strictly control parameters such as temperature, pressure, and the amount of ethylene oxide used.
Structurally, HEC maintains a flexible chain configuration due to its polymeric nature. This elasticity allows HEC to exhibit unique rheological properties, such as pseudoplasticity (shear-thinning behavior). When subjected to stress, the HEC solutions become less viscous, enabling easier application in topical formulations or coatings. Upon removal of stress, the viscosity returns to its original state, which is particularly advantageous in industries like construction, where HEC is used as a thickener in adhesives and paints.

HPMC is synthesized from cellulose, a naturally occurring polymer made of β-D-glucose units linked by β(1→4) glycosidic bonds. The modification of cellulose to produce HPMC involves two key processes methylation and hydroxypropylation. Methyl groups (–OCH3) are introduced to the cellulose backbone, replacing some of the hydroxyl groups (–OH), while hydroxypropyl groups (–O-CH(CH3)2) are added to enhance solubility and functional properties. The resulting structure maintains the fibrous backbone of cellulose but introduces hydrophobic and hydrophilic characteristics that significantly affect its behavior in solution.
