Denatonium Benzoate is globally recognized as the most bitter substance known to science, used primarily as an aversive agent. It is available in 99% Purity and is effective at concentrations as low as 10 parts per million.

This Technical Grade solid is essential for denaturing alcohols and preventing accidental ingestion of hazardous household products. Its high stability across various temperatures and pH levels makes it an ideal additive for diverse liquid formulations.

In the automotive sector, it is a mandatory additive for antifreeze and coolants to protect wildlife and children. The compound’s odorless property ensures it does not interfere with the primary fragrance or function of the end product.

Denatonium Benzoate

  • Alcohol Denaturation: Added to ethanol and isopropyl alcohol to make them unfit for human consumption, often for tax or safety purposes.
  • Automotive Fluids: Integrated into ethylene glycol-based antifreeze and windshield washer fluids as a safety bittering agent.
  • Household Products: Used in liquid detergents, disinfectants, and garden chemicals to discourage accidental swallowing.

Classified as Acute Toxic (Oral) and a Skin/Eye Irritant. While used in small doses, the pure form requires Dust Masks (N95), Safety Glasses, and Protective Gloves during blending.

Commonly supplied in 1 kg Tins, 5 kg Foil Bags, and 25 kg Fiber Drums for large-scale industrial compounding.
