Costavaras, T.A., Froment, M., Goff, A.H., and Geogolis, C., J. Electrochem. The results indicate that the presence of a benzene ring in saccharin, benzene sulfonic acid and benzothiazole cause these molecules to move from the electrolyte to the electrode surface and, by blocking the electrode surface, enhance the grain size and produce nickel coatings with an average grain size below 50 nm. [17] Saccharin in toothpaste can cause burning sensations, swelling, and rashes of the mouth and lips in sensitive individuals.
