Abstract
Abstract A solvent composition is provided which will efficiently remove medical adhesives, particularly adhesives containing silicone resins, from skin and simultaneously replace body oils, and prepare the skin to receive subsequent applications of the adhesive. The solvent composition comprises a major effective amount of a liquid aliphatic hydrocarbon solvent fraction, preferably a C8 to C11 aliphatic hydrocarbon fraction, a minor effective skin conditioning amount (generally comprising at least about 2 weight percent) of silicone fluid, and preferably, a minor effective amount of a flash point suppressant for the liquid aliphatic hydrocarbon fraction.
