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.
The combination of HPMC and CMC can create a synergistic effect, enhancing their individual properties for better performance in practical applications. In the pharmaceutical industry, HPMC is often employed in the formulation of tablets and capsules, serving not only as a binder but also as a stabilizing agent. When combined with CMC, the gel-forming properties of the combination can lead to improved drug delivery systems, allowing for sustained drug release and better bioavailability.
hpmc cmcThis modification enhances the solubility of cellulose in water, allowing HEC to dissolve and form viscous solutions. The presence of hydroxyethyl groups increases the hydrophilicity of the cellulose molecule, which is critical for its functionality in various applications. The degree of substitution, which indicates the average number of hydroxyethyl groups attached per anhydroglucose unit, affects the properties of HEC such as its solubility, viscosity, and gel-forming ability. Generally, higher degrees of substitution result in better soluble derivatives and higher viscosity of the solutions.
