Composition and Efficacy of Essential Oil Nanoemulsions

Essential oil, endorsed as a natural cum powerful ingredient, encompasses incredible properties, and various approaches have been proposed and spurred over the last decades. One among them is the nano-emulsification of the essential oils, and the sub-micron size provides prolonged shelf life, ease of formulation and handling, nullification of the stated obstacles, as well as the augmentation of the essential oil antimicrobial activity. This chapter primarily reinforces and is well-articulated on (1) the components and its precise concentration adequate to fabricate nanoemulsion; (2) critical analysis on the experimentally inferred antimicrobial mechanism and the extent of contribution granted by the optimal concentration of the components in the nanoemulsion; (3) scrutinization of the possible impact rendered by the components on the other characteristics of nanoemulsion aside from antimicrobial potency. Altogether, the importance of careful formulation of the essential oil-loaded nanoemulsion is emphasized extensively.
