Use

Ingested benzoic acid is conjugated with glycine in the liver to yield hippuric acid, which is then excreted in the urine; care should be taken when administering benzoic acid to patients with chronic liver disease. Benzoic acid is a gastric irritant, and a mild irritant to the skin. It is also a mild irritant to the eyes and mucous membranes. Allergic reactions to benzoic acid have been reported, although a controlled study indicated that the incidence of urticaria in patients given benzoic acid is no greater than in those given a lactose placebo. It has been reported that asthmatics may become adversely affected by benzoic acid contained in some antiasthma drugs. The WHO acceptable daily intake of benzoic acid and other benzoates, calculated as benzoic acid, has been set at up to 5 mg/kg body-weight. The minimum lethal human oral dose of benzoic acid is 500 mg/kg body-weight. LD50 (cat, oral): 2 g/kg LD50 (dog, oral): 2 g/kg LD50 (mouse, IP): 1.46 g/kg LD50 (mouse, oral): 1.94 g/kg LD50 (rat, oral): 1.7 g/kg
