Abraxodyne Chemical (commonly shortened to Abraxodyne or Abraxo) was a pre-War company which produced detergents and other cleaning-related products and a fully owned subsidiary of RobCo Industries.
The company's most well-known product was Abraxo cleaner, a household detergent widely used in Washington, D.C., Boston, Appalachia and the southwest U.S. before the Great War. Its product range also included a food sanitizer designed to unlock additional nutritional value in food and beverages by removing trace bacteria. Abraxodyne Chemical is a fully owned subsidiary of RobCo Industries.
Two products of the company, Abraxo cleaner, and the food sanitizer, appear in Fallout 3, while only the Abraxo cleaner appears in Fallout: New Vegas. Abraxo cleaner and Abraxo cleaner industrial grade appear in Fallout 4 and Fallout 76.
