Abstract: The invention relates to a multi-layered wound dressing, particularly for the moist wound treatment, comprising a first layer as a wound contact layer, which contains an aqueous hydrogel matrix, and at least a second absorbing layer. The hydrogel matrix comprises 37 to 43% by weight of propylene glycol, a prepolymer with isophorone diisocyanate groups and a diamine on the basis of polyethylene oxide in an amount of a total of 12 to 16.5% by weight, 0 to 5% by weight of an inorganic chloride, and the remainder water, wherein the ratio of the reactive groups of isocyanate to the amine groups of the diamine should be 1.25 to 1.35.

Abstract: The invention relates to a multilayer wound dressing, in particular for moist wound treatment, comprising a first layer as an absorbent layer, which comprises a hydrogel matrix, and at least one second layer, which is applied to the first layer on the side facing away from the wound. The hydrogel matrix comprises 54 to 60 wt % of propylene glycol, a pre-polymer having isophorone diisocyanate end groups and a diamine based on polyethylene oxide in a quantity of a total of 38 to 42 wt %, 0 to 5 wt % of an inorganic chloride, and the remainder water, wherein the ratio of the reactive groups of isocyanate to the amine groups of the diamine is intended to be 1.25 to 1.35.
