Introduction to Denatonium Benzoate Anhydrous

Denatonium benzyl is a quaternary ammonium salt formed by combining a quaternary ammonium salt cation with an inert anion such as benzoate ion or saccharin anion. The structure of Denatonium Benzoate Anhydrous cation is similar to that of the local anesthetic lidocaine, the only difference being the addition of a benzyl functional group on the nitrogen atom of the amino group.

Denatonium Benzoate is the most bitter compound known in the world. If the bitterness of quinine is established as the benchmark 1, the anger of this item is 1000, and the focus of the option is 10ppm. For most people It is already unbearably bitter. Most of the applications of Denatonium Benzoate Anhydrous are related to its bitter taste. It is a cheap and efficient substitute for sambarine, kaolin, quinine, koji glycoside and naringin.

Denatonium benzoate is typically made use of as an aversive agent to prevent people from unintentionally ingesting other toxic yet unsavory compounds.
