The primary use of chlorine is in the production of various plastics and artificial fibers, such as polyvinyl chloride. Chlorine is also used as a disinfectant for public water supplies and is an important component of several pharmaceuticals. Chlorine can also bond with an oxygen atom to form sodium hypocrite, which acts as a bleach<ref> http://www.eurochlor.org/products </ref>.
