Abstract
A wound dressing comprising a substrate comprising a plurality of fibers, at least one antimicrobial agent in the substrate, and an oil emulsion on at least a portion of the substrate is disclosed. The at least one antimicrobial agent can be polyhexamethylene biguanide, and the oil emulsion can consist essentially of a petrolatum in a range of from about 75 wt % to about 90 wt % of the oil emulsion, a mineral oil in a range of from about 10 wt % to about 20 wt % of the oil emulsion, water in a range of from about 0.1 wt % to about 1 wt % of the oil emulsion, and at least one surfactant in a range of from about 1 wt % to about 5 wt % of the oil emulsion.
