Journal of Toxicology and Environmental Health, Part B, 26(6), 307-341. In-vitro screening reported genotoxicity for sucralose-6-acetate, a compound that arises as a manufacturing impurity of sucralose and can also be formed when gut bacteria acetylate sucralose. The work is cell-based screening, not human exposure data.
