Development of an Antibacterial Impregnated Support using Citrus Sinensis Essential Oil as Active Ingredient

Abstract

Introduction: Nowadays one of the products with the highest consumption in the cosmetic industry are impregnated supports due to their different functions, which has made them one of the most common items in the daily hygiene of many individuals and families.

Objective: To develop antibacterial impregnated carrier using Citrus sinensis essential oil as active ingredient.

Methods: The essential oil was obtained by microwave radiation-assisted hydro distillation from the pericarp of the fruits; the chemical composition was evaluated by gas chromatography/mass spectrometer. Impregnated supports were prepared using essential oil as active ingredient at concentrations of 1.5 % and 2 %, then microbiological parameters were evaluated on bacterial strains of Echericha coli ATCC 25922 and Staphylococcus aureus ATCC 25923.

Results: The essential oil extracted from Citrus sinensis presented limonene as the major component and it was found that the suitable formulations were those in which orange essential oil was found at concentrations of 2 %, as they presented activity against the bacterial strains in question.

Conclusions: The antibacterial impregnated carriers formulated from 2 % of Citrus sinensis essential oil showed promising chemical and microbiological indicators; and provide an indication of correct formulation from the galenic point of view.
