text: Diphoterine solution contains an amphoteric, chelating molecule: a substance which is capable of reacting with both acids and alkalis when applied to either type of chemical spill, stopping the aggressive action of a corrosive or irritant chemical, halting the reaction with the body.
  However, it is not fully effective at halting the body's reaction with hydrofluoric acid. This is because hydrofluoric acid is poisonous as well as corrosive. Treatment with either Hexafluorine or calcium gluconate is required to deal with hydrofluoric acid contamination.
  Like all of the emergency treatments, Diphoterine solution is not a substitute for professional medical attention, so immediate attention from emergency medical personnel should always be sought, especially if the chemical spill was to the eye.
