An antibacterial composition comprising thymol and totarol. This combination provides synergistic effect against gram negative and gram positive bacteria.

A method for forming a composition that includes mixing an antimicrobially active botanical oil (e.g., thymol, carvacrol, etc.) and a modified starch polymer within a melt blending device (e.g., extruder) is provided. Unlike the problems associated with proteins, the use of starch polymers allows for a greater degree of flexibility in the processing conditions and is still able to achieve good properties in the resulting composition. The present inventors have also discovered that a plasticizer may be employed to facilitate melt processing of the starch, as well as to enhance the ability of the botanical oil to flow into the internal structure of the starch where it can be retained in a stable manner. The composition is also typically generally free of solvents. In this manner, the starch will not generally disperse before use and prematurely release the botanical oil. Due to the water sensitivity of the modified starch, however, it may be subsequently dispersed by moisture when it is desired to release the botanical oil.
