Abstract: An antimicrobial composition may comprise a surfactant. The antimicrobial composition may include about 30 ?g/ml to about 1,000 ?g/ml of the surfactant, by volume of the antimicrobial composition. The surfactant may comprise a docusate salt such as docusate sodium. The antimicrobial composition may comprise an antimicrobial agent. The antimicrobial composition may include from about 0.01% to about 10% of the antimicrobial agent, by weight of the antimicrobial composition. The antimicrobial agent may comprise polyhexanide (PHMB). In some embodiments, the antimicrobial composition may comprise a matrix-forming material. The antimicrobial composition may include at least 90% of the matrix-forming material, by weight of the antimicrobial composition. The matrix-forming material may comprise collagen, oxidized regenerated cellulose, alginate, carboxymethylcellulose, or combinations thereof.

Abstract: The invention provides wound dressings, in particular wound dressings of low- or non-exuding wounds a bleeding wounds. The wound dressings are of the island type, having as adhesive-coated backing sheet (6) and an absorbent island (9) supported on the backing sheet. The island (9) comprises a layer (2) of liquid absorbent material enclosed in an envelope of textured perforated thermoplastic film. The film (3) at one side of the island (9) presents a ribbed or embossed perforated surface having low adherency to the wound. The film island an the rear surface of the envelope is perforated and smoothed to provide good attachment to the backing sheet (6) and controlled water vapor transmission rate. The invention also provides a method of manufacture of the wound dressings according to the invention, according to which the absorbent layer (2) is wrapped in a textured perforated thermoplastic film, and the film on the rear face of the envelope is then preferably smoothed by blowing hot air onto it.
