Web24 jul. 2024 · Classic toxicology on benzoic acid/sodium benzoate is not easy, because it's so nontoxic. Values up to 5 to 10 grams per kilo have been reported as the median lethal dose in rats, which is a huge, whalloping amount. If true, that's less acutely toxic than table salt; sodium chloride has an LD50 of about 3 grams/kilo in the rat.
