Dressing oil emulsion 3"x3" - Nonadhering dressing with petrolatum. Specially formulated petrolatum promotes healing while protecting wound. These nonadhering dressings are made of knitted cellulose acetate and are ideal for almost any draining wound. The uniform and porous material does not occlude exudate flowing from the wound. This helps prevent pooling of fluid at the wound site. You can cut the dressing to fit a wound without it unraveling and shredding.
