Hypochlorites are the most commonly used of the chlorine based disinfectants, are fast acting & economical. Sodium hypochlorite (chlorine bleach) is strongly oxidizing with a broad range antimicrobial action that can disrupt or destroy bacterial cell membranes. This happens because cell walls of pathogenic microorganisms are negatively charged. Hypochlorite germicidal activity is directed towards important bacterial enzymes which in turn disrupts metabolic pathways. Effectiveness of hypochlorite (chlorine bleach) solutions are reduced in the presence of organic compounds such as blood and feces. Higher concentrations are often required to break down biofilms.
Hypochlorite ion (OCl-, shown in the image below) reacts with water to form hypochlorous acid (HOCl) that is the actual disinfecting compound. The amount of hypochlorous acid and hypochlorite together equals available or free chlorine. Its broad range of antimicrobial action is unaffected by water hardness. In high enough concentration, it can effect a 5-log reduction (99.999% inactivation) in pathogenic organisms in under 10 minutes.
Indigo® chlorine test strips measure concentrations ranging from 0.5ppm to 10,000ppm high levels for applications ranging from water treatment, food service, biofilms to medical devices & more. Whatever your strength requirement for chlorine bleach/hypochlorite, Indigo® chlorine test strips can confirm your disinfectant solutions are correctly diluted for optimum effectiveness.

Chlorine (sodium hypochlorite) is the most popular sanitizing/disinfecting chemical for hard surfaces especially where food is prepared. Iodine, also a halogen, is listed below but is used relatively rarely by comparison.

Warning. Chlorine use in sanitation and disinfection has rare cases of serious toxicity but careful handling is nevertheless recommended. Fumes from undiluted household bleach can cause eye irritation. Ingestion can cause oropharyngeal, esophageal & gastric burns. Nitrile gloves, safety glasses and lab coat/apron are the minimum recommended PPE (personal protective equipment) for handling concentrated chlorine bleach.
Never mix chlorine bleach-sodium hypochlorite with ammonia based cleaners which can release toxic levels of ammonia and chlorine gas
Consult first aid instructions on bleach container & seek medical aid if necessary in the event a spill or mishap.
