Pectin: Locust Bean Gum: PVA Patches Enriched with Tea Tree Oil in Bulk and Nanoemulsion Forms: Formulation and Characterization

Abstract
In this study, pectin (PEC) and locust bean gum (LBG) polymers were used on the basis of polyvinyl alcohol (PVA) matrix in order to obtain biofunctional thin films. In the first stage of the study, thin films containing pectin and LBG in different ratios were produced under fixed PVA concentration; these films were evaluated according to their potential to be used as wound dressings by various physicochemical analyzes such as chemical structure, morphology, wettability and mechanical properties. As a result of the evaluations, film samples with optimum composition were determined and Tea Tree Oil (TTO) was added to these samples both directly (bulk, EO) and in nanoemulsion (NEO) form. By adding the bioactive agent in two different forms, it was aimed to maintain or improve the optimum film properties; comprehensive physicochemical analyzes were carried out in this direction. The obtained preliminary optimization results provide preliminary information that will guide especially for future studies on material production processes and material-TTO composition.
