What is the Chlorine Institute?

The Chlorine Institute (CI) founded in 1924, is a technical trade association of companies that are involved in the safe production, distribution and use of chlorine, sodium and potassium hydroxides and sodium hypochlorite, and the distribution and use of hydrogen chloride.
