We manufacture denatonium benzoate, the worlds bitterest substance. Denatonium Benzoate is recognized as the bitterest substance known to man. Denatonium benzoate is a powerful deterrent against possible poisoning, especially in young children and pets. In only minute quantities, potentially harmful household, industrial or automotive products are rendered unpalatable. This additive has been thus described as the bitterest compound known. Being non toxic, clear and odorless, it will not change your product, it will only make it taste awful!!!
