Development of a Low-Temperature Process for the Formulation of Nanoemulsion-Gel Encapsulating Essential Oil: Investigation on the Wound Healing Effect

Abstract

This study develops an efficient, low-temperature process for formulating a nanoemulsion-based gel encapsulating Pituranthos tortuosus's essential oil, investigating its wound healing potential. The novel process ensured stable encapsulation of the medicinal plant's oil. The nanoemulsion was characterized using dynamic light scattering and transmission electron microscopy, followed by in vitro and in vivo tests to examine wound healing efficacy. Results revealed the gel's excellent stability, high encapsulation efficiency, and significant wound-healing effects. This research provides a new method for formulating Pituranthos tortuosus's essential oil nanoemulsion-based gel, emphasizing the potential role of plant-based therapies in healthcare advancement, and invites further exploration into the therapeutic applications of essential oil-encapsulating nanoemulsions.
