The dose makes the poison inferred

A reported rat oral LD50 for Benzophenone is 1,900 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:

133.0 g
a median lethal dose scaled to 154 lb (133,000 mg)

“The dose makes the poison” is a cross-species estimate shown as neutral science, not a threshold anyone should act on. Real toxicity depends on the person, not body mass alone.
