Sodium saccharin did not induce prophage and wasn't mutagenic to S. typhimurium strains TA100, TA1535, TA1537, TA1538, TA98, TA92 or TA94 inside the existence or absence of the exogenous metabolic activation procedure. In one study, both equally a purified and an unpurified sample of sodium saccharin induced gene conversions, mitotic recombination and reverse mutation in Saccharomyces cerevisiae.
A further study showed that 90% of [14C]sodium saccharin was excreted unchanged inside the urine by rats and monkeys of each and every sexual intercourse. Pretreatment with phenobarbital to induce blended-functionality oxidase exercise or prior consumption of each day doses of sodium saccharin for more than website two years didn't affect the metabolism of one oral dose of [14C]saccharin (Byard & Goldberg, 1973).
