Patch comprising an adhesive layer having a nonfunctional silicone oil

A patch comprising an adhesive layer and a release liner laminated on at least one surface of a backing, wherein

• the adhesive layer comprises, as an adhesive base agent, at least one selected from the group consisting of acrylate-based adhesives and rubber-based adhesives,
• the adhesive layer comprises, as a plasticizer, at least one selected from the group consisting of liquid paraffin, liquid polybutene, isopropyl palmitate, isopropyl myristate, diethyl sebacate, and hexyl laurate,
• the adhesive layer comprises, as a transdermal absorption enhancer, at least one selected from the group consisting of fatty acids having a carbon chain of 6 to 20 carbon atoms and aliphatic alcohols having a carbon chain of 6 to 20 carbon atoms, and
• the adhesive layer comprises 0.3 to 3% by mass of a nonfunctional silicone oil having a kinematic viscosity of 20 to 250 cSt at 25° C. wherein the nonfunctional silicone oil is at least one selected from the group consisting of dimethylpolysiloxane and methylphenylpolysiloxane.
