There provided a percutaneous administration tape preparation which can attach well to the skin surface even in the case of the permeation of water after attaching and can be easily detached from the skin surface without giving the skin simulation such as peeling off and the injury of the horny layer. The percutaneous administration tape preparation comprises a sheet-form support, a drug-containing pressure-sensitive adhesive layer, and a separator, wherein the drug-containing pressure-sensitive adhesive layer comprises a uniform dispersed state containing from 50 to 95% by weight one or more kinds of elastomers, from 5 to 50% by weight a hygroscopic material, and a percutaneous absorption drug so that a part of the hygroscopic material contained therein remains on the applied surface at detaching the tape preparation from the applied surface.

Percutaneous administration tape preparation

A dressing comprising a backing and an adhesive layer, wherein the backing is moisture-permeable and the adhesive layer comprises an adhesive composition comprising a rubber-based adhesive, a polymer having a water-absorbing property and/or a water-swelling property, and a metal oxide and/or a metal salt, the polymer having the water-absorbing property and/or the water-swelling property being a polymer containing a functional group having an ability to form a salt and/or coordination compound.

Absorbent dressing having backing and continuous adhesive layer

A depilation method is disclosed, comprising coating a depilatory agent containing an aqueous solution or emulsion of a polymer compound having a film forming ability and a depilatory medicine, drying the resulting coating to form a film and peeling off the film. This method permits to remove hair without causing any pain and producing any unpleasant odor due to the decomposition of hair.

Depilation method

An electrode pad comprising a tacky crosslinked hydrogel adhered to an electrode terminal plate, through which electrical signals from the living body can be transmitted to an electric recording apparatus.
