essential oils

 The study is devoted to the development and evaluation of alginate hydrogel plates modified with tea tree and rosemary essential oils as a potential wound treatment material. The introduction of these oils into the hydrogel has led to a significant increase in the antibacterial properties of the hydrogel, making it effective against pathogens. Importantly, the inclusion of essential oils does not impair the physical, mechanical, and operational characteristics of hydrogel plates.

This study explores the effectiveness of β-cyclodextrin (β-CD) as a carrier for essential oils (EOs), specifically d-limonene, and eugenol, within biodegradable delivery systems. Inclusion complexes were prepared via coprecipitation and analyzed using Fourier-transform infrared spectroscopy. FTIR analysis confirmed the encapsulation, indicated by the shift in the O-H stretching vibrations of β-CD and a reduction in the intensity of the C-H stretching vibrations of d-limonene, which suggests successful molecular inclusion.
