Abstract
A composition and method is provided capable of removing contaminants from the surface of a gelatin capsule, such as a paint ball, to allow the gelatin capsules to be used for their intended use. The composition comprising, by weight, about 70 to 99.9 percent of a water-soluble alcohol, about 0.1 to 30 percent water, about 0.1 to 10 percent of a volatile silicone, and about 0.1 to 1 percent of a non-volatile silicone. Furthermore, the composition prevents excessive swelling of the gelatin outer shell of the gelatin encapsulated product. A method is also provided for cleaning a gelatin encapsulated product comprising the steps of contacting the gelatin encapsulated product with a cleaning composition, separating the gelatin encapsulated product from the cleaner, and drying the gelatin encapsulated product. The gelatin capsule may be a paintball. The composition may include additives to improve the performance of the gelatin capsules.
