Formulation and Characterization of Potential Antifungal Oleogel with Essential Oil of Thyme

Abstract EN

The aim of this research was to formulate oleogel with thyme essential oil with potential antimicrobial activity, design optimal formulation, and evaluate the influence of ingredients on texture parameters of preparation.

Central composite design was applied to statistical optimization of colloidal silica and paraffin oil mixture for the modeling of oleogel delivery system.

The influence of designed formulations on response variables (texture parameters), firmness, cohesiveness, consistency, and index of viscosity, was evaluated.

Quality of essential oil of thyme was assessed by determinate concentration of thymol and carvacrol using gas chromatography with flame ionization detection (GC-FID).

Microbiological tests have shown that oleogel with thyme essential oil affects Candida albicans microorganism when thyme essential oil’s concentration is 0,05% in oleogel mixture.
