Abstract
This study evaluated hydrogels containing Celugel, 3% hop cone extract obtained from Humulus lupulus L. using supercritical carbon dioxide extraction substrate, and 1% and 2% chitosan for dermatological application to treat inflammatory skin conditions. The presence of chitosan significantly affected the rheological properties of the formulations, including their dynamic viscosity, hardness, consistency, cohesiveness, and blurring time. The formulations containing 2% chitosan showed the best application possibilities. The formulations were evaluated for dissolution of cohumulone, which is an analogue of humulone contained in hop cone extract. The concentration of chitosan in the formulations had a significant effect on the dissolution testing parameters of the active ingredient: as the chitosan concentration increased, the desired effect of prolonged release time of the active ingredient was achieved while maintaining the membrane-forming properties of Celugel.
期刊介绍：
Progress in the Chemistry and Application of Chitin and its Derivatives is an annual journal focused on all aspects of production, modification, enzymology and application of chitin and its many derivatives, including chitosan. The journal publishes full-length papers as well as invited reviews. To be considered, papers must present original research that has not been published or accepted for publication elsewhere. The language of the journal will be English.
