Abstract:
A method for producing a gel patch comprising an adhesive mass layer on a backing fabric, comprising a step of applying a composition comprising a physiologically active substance, a water-soluble polymer, glycerin, and water to the backing fabric to form the adhesive mass layer, wherein a loss tangent of the composition in dynamic viscoelasticity measurement at 1 Hz at a time of application to the backing fabric is 0.75 to 1.
