Sodium saccharin is useful in the electroplating industry as an additive in metalworking fluids and adhesives. The electroplating of nickel, for instance, uses saccharin as an electrolyte (a substance, which when dissolved in a solution, makes it electrically conductive). Electroplating is the process in which an electric current is applied through a solution to coat the surface of a metal with another layer of metal. The nickel electroplating industry uses sodium saccharine bring about a brighter finish. Gold and palladium electroplating baths also use sodium saccharin.
