When ingested at 10 ppm by human beings, denatonium benzoate has an extremely bitter, unpleasant taste.  |  The use of bittering agents, such as denatonium benzoate, could reduce the ingestion of toxic substances by dogs, cats, other animals and children and warrants further investigation. The efficacy and toxicity studies on denatonium benzoate are limited and may be subject to varying interpretations when viewed in the context of a potential poisoning situation. Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex or Aversion) and as denatonium saccharide (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. is extremely bitter and unlikely to be ingested in any appreciable amount by humans. Be the First to Share. Research on the effectiveness of denatonium benzoate as a deterrent to liquid detergent ingestion by children. Post application Non-Occupational Exposure and Risk Assessment. Research shows that people can detect Denatonium benzoate in water at 50 parts per billion. Detection of potentially harmful, even toxic, compounds is one of the primary roles of bitter taste. We thought you might ask that. Considering its wide availability as a denaturant for alcohol, it is surprising that human toxicity has been reported only once. Fundam Appl Toxicol.
