Thyme essential oil (TEO) is a natural phenolic compound and has high antimicrobial and antioxidant activity. However, essential oils are very sensitive to environmental conditions and have high volatility and poor solubility that limit their applications. In this study, the incorporation of TEO into the β-cyclodextrin nanosponges was investigated. Di-Ph carbonate was used as cross-linker. The characterization of the obtained nanosponges was done by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform IR spectroscopy (FTIR), andthermogravimetric analyzer(TGA). Encapsulation efficiency, loading capacity, solubility, and antibacterial properties of the TEO-nanosponges were analyzed. The TEO-nanosponges showed porous structures with an average size lower than 326 nm. The results of FTIR and XRD confirmed the incorporation of TEO into the nanosponges. Thermogravimetric anal. indicated that the inclusion complex of TEO and nanosponges enhanced the thermal stability of TEO significantly. The inclusion complex of TEO into the nanosponges increased its antibacterial activity. The aqueous solubility of TEO was enhanced by 15-folds after encapsulation within nanosponges. Min. inhibitory concentration of TEO was decreased up to 29.4 folds after encapsulation into the nanosponges. The results suggest that β-cyclodextrin nanosponges can potentially be used as a delivery system for hydrophobic and sensitive compounds to increase their usage in the pharmaceutical and food industries. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Recommanded Product: Diphenyl carbonate).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Recommanded Product: Diphenyl carbonate
