Evaluation of the thermal stability of β-cyclodextrin inclusion complexes with four essential oils

Abstract

Using Thermogravimetric Analysis (TGA-DSC), the thermal characteristics of the essential oil/β-CD inclusion complexes were assessed. The findings showed that, in comparison to the pure essential oils, the inclusion complexes had noticeably improved thermal stability. This enhancement is ascribed to the encapsulating effect of β-CD, which offers a shielding structure that stops the heat deterioration of the essential oils. The study comes to the conclusion that essential oils are better suited for applications that demand more thermal resistance because β-CD effectively increases their thermal stability.
