Abstract: Adhesive compositions are provided that include a crosslinked silicone gel, a hydrophilic component dispersed in the silicone gel, and an antimicrobial agent dispersed in the silicone gel. The adhesive composition is readily applied to (and removed from) skin, and has desirable hydrophilic and antimicrobial properties. Advantageously, the hydrophilic component in the crosslinked silicone gel is not readily extractable (e.g., into a pH 7 buffer). Surprisingly, the combination of hydrophilic component with antimicrobial agent in the crosslinked silicone gel can provide a synergistic level of antimicrobial activity.

Abstract: Adhesive articles that include a substrate and a silicone adhesive are disclosed. The articles also include a polymer containing poly(propylene oxide) units and optionally poly(ethylene oxide) units and having a number average molecular weight of at least 1000 grams per mole. The polymer may either be incorporated into the substrate or may be used as a primer on the substrate. If the polymer includes poly(ethylene oxide) units, the copolymer typically has a weight ratio of poly(ethylene oxide) to poly(propylene oxide) of up to 3:1, or if the copolymer has a number average molecular weight of at least 10,000 grams per mole, the weight ratio of poly(ethylene oxide) to poly(propylene oxide) is up to 2:1. Methods of making the adhesive articles are also disclosed.
