Calgon

WHAT IS CALGON?

The original product consisted of powdered sodium hexametaphosphate Na₆O₁₈P₆  (amorphous sodium polyphosphate), which in water would complex with ambient calcium ion and certain other cations, preventing formation of unwanted salts and interference by those cations with the actions of soap or other detergents. Its name was a portmanteau derived from the phrase “calcium gone”.
