Sodium Hypochlorite

Sodium hypochlorite (NaOCl) is a solution made from reacting chlorine with a sodium hydroxide solution. These two reactants are the major co-products from most chlor-alkali cells. Sodium hypochlorite, commonly referred to as bleach, has a variety of uses and is an excellent disinfectant/antimicrobial agent.

The Institute produced the following materials to address key areas important for both safety and successful use. These documents can be downloaded free of charge. If you produce or use sodium hypochlorite, CI strongly suggests that you also consider obtaining Pamhplet 96, Sodium Hypochlorite Manual and the Handling of Sodium Hypochlorite Safety Video. These products can be ordered on this website in the CI Bookstore.
