    摘要: The invention concerns a patch for the controlled release of readily available volatile active substances to the skin, the patch comprising a back layer and, bonded to it, a water-insoluble adhesive film consisting of a pressure-sensitive fusion adhesive, plus a detachable film covering the adhesive film. The patch is characterized in that the pressure-sensitive fusion adhesive contains a triple-block copolymer of polystyrene block copoly(ethylene/butylene) block polystyrene (SEBS) at a concentration of 10 to 80% by wt., and an active substance which, at the temperature at which the adhesive bonds, is a readily volatile liquid, and which is present at a concentration of 2.5 to 25% by wt.

    摘要: A method of preparing a patch for the controlled release of readily available volatile active substances to the skin is disclosed. The patch comprises a back layer, and, bonded to the back layer, a water-insoluble adhesive film consisting of a pressure-sensitive fusion adhesive, plus a detachable film covering the adhesive film. The pressure-sensitive fusion adhesive contains a triple-block copolymer of polystyrene block copoly(ethylene/butylene) block polystyrene at a concentration of 10 to 80% by wt., and an active substance at a concentration of 2.5 to 25% by weight, which is a readily volatile liquid at the temperature at which the adhesive bonds.
