Abstract
A silicone adhesive composition used for adhering a device or a substance to a wet surface contains (i) a silicone resin that is cohydrolysis product of a trialkyl hydrolyzable silane and an alkyl silicate in which the cohydrolysis product contains a plurality of silicon-bonded hydroxy groups; (ii) a linear organopolysiloxane fluid containing terminal silicon-bonded hydroxy groups having a viscosity above 200,000 mm/at 25° C.; (iii) a trialkylsiloxy terminated polyorganosiloxane fluid having a viscosity of 100,000-600,000 mm/at 25° C.; (iv) a water soluble muco-adhesive polymer selected from the group consisting of a poly(ethylene oxide) polymer having a molecular weight of 100,000 to 8,000,000, an acrylic acid polymer having a molecular weight of 500,000 to 4,500,000,000, and a hydroxyethylcellulose polymer having a molecular weight of 90,000 to 1,300,000,000; and optionally, (v) a solvent selected from the group consisting of aliphatic hydrocarbons, aromatic hydrocarbons, esters, volatile linear and cyclic silicone compounds. Other components such as a silicone polyether, a silicone wax, a drug, an excipient, and/or an active ingredient can also be included.
