Sr. Hansen et al., DENATONIUM BENZOATE AS A DETERRENT TO INGESTION OF TOXIC-SUBSTANCES -TOXICITY AND EFFICACY, Veterinary and human toxicology, 35(3), 1993, pp. 234-236
When ingested at 10 ppm by human beings, denatonium benzoate has an ex
tremely bitter, unpleasant taste. The addition of denatonium benzoate
to liquid dish detergents and orange juice reduces the amount ingested
by children. The toxicity of denatonium benzoate is low with acute po
LD50's in rats of 485-740 mg/kg. The use of bittering agents, such as
denatonium benzoate, could reduce the ingestion of toxic substances b
y dogs, Cats, other animals and children and warrants further investig
ation.
