An oil-in-water emulsion that is environmentally friendly and also exhibits antimicrobial activity is provided. More specifically, the oil phase of the emulsion includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil tends to leach out of the emulsion during storage and before it is used in the desired application, a water-dispersible polymer is also employed in the aqueous phase of the emulsion to enhance long term stability of the oil and, in turn, antimicrobial efficacy. Without intending to be limited by theory, it is believed that the water-dispersible polymer can effectively encapsulate the botanical oil within the emulsion and inhibit its premature release. Once the emulsion is formed, water can then be removed so that it becomes a substantially anhydrous concentrate. In this manner, the water-dispersible polymer will not generally disperse before use and prematurely release the botanical oil. When it is desired, moisture may simply be re-applied to the concentrate to disperse the polymer and activate the release of the botanical oil. Of course, to provide the optimum degree of biocompatibility, the water-dispersible polymer is also a "biopolymer" that is biodegradable and/or renewable. Se proporciona una emulsión de aceite-en-agua que es ambientalmente amigable y que también exhibe actividad antimicrobial. Más específicamente, la fase de aceite de la emulsión incluye un aceite botánico derivado de una planta (por ejemplo timol, carvacrol, etc.). Debido a que el aceite botánico tiende a filtrarse afuera de la emulsión durante el almacenamiento y antes de que este sea usado en la aplicación deseada, un polímero dispersable en agua también es empleado en la fase acuosa de la emulsión para mejorar la estabilidad a largo plazo del aceite y, a su vez, la eficacia antimicrobial. Sin intentar el estar limitado por la teoría, se cree que el polímero dispersable en agua puede efectivamente encapsular el aceite botánico dentro de la emulsión e inhibir su liberación prematura. Una vez que la emulsión es formada, el agua puede entonces ser removida de manera que esta se haga un concentrado anhidro esencialmente. En esta manera, el polímero dispersable en agua no generalmente se surtirá antes del uso y prematuramente liberar el aceite botánico. Cuando se desea, la humedad puede simplemente ser aplicada de nuevo al concentrado para dispersar el polímero y activar la liberación del aceite botánico. Desde luego, para proporcionar el grado óptimo de biocompatibilidad, el polímero dispersable en agua también es un "biopolímero" que es biodegradable y/o renovable.
