The invention relates to materials that are to be applied to the skin,preferred materials being polymers, cosmetics, cleaning preparations, andcloths, pads, or dressings. Polyurethanes which are preferably provided withself-adhesive properties and have an antimicrobial effect are preferred aspolymers. The combination of materials, especially polymeric materials such aspolyurethane, and specific silver-containing glasses provides for moist woundhealing while ensuring high product stability and high stability againstdiscoloration of the wound dressing. The antimicrobial silver-containingglasses comprise 40 to 75 mole percent of P2O5, 35 to 55 mole percent of CaO,MgO, 0 to 5 mole percent of Na2O, K2O, 5 to 20 mole percent of SiO2, Al2O5,and 0.1 to 5 mole percent of Ag2O, the percentages being relative to the glasscomposition.
