Pre-cleaning required? Yes Yes Yes, with the exception of fourth generation QUATs. Yes Yes Yes Yes
Shelf Life Unmixed with water: 3months. Mixed: 24hours. Keep in an airtight container away from light. 1 year in a sealed container if undiluted. 2 years in an airtight container if undiluted. 2 years in an airtight container away from light. 2 years if undiluted. Store in a cool, well-ventilated area. 2 years if undiluted. Once solutions have lost their brown colour to become colourless, they are no longer active. <48 hours.
Health risks Irritant to mucous membranes, eyes and skin. If mixed with ammonia or acidic products can create poisonous chlorine gas. Carcinogenic. Irritant to mucous membranes, eyes and skin. Can cause dermatitis. Irritant to mucous membranes. Can trigger asthmatic symptoms. Irritating to eyes, skin at mucous membranes at 6% concentration. Inhalation or contact with material may irritate or burn skin and eyes. Vapours may cause dizziness or suffocation. Non-toxic and non-irritating in normal use. Occasional hypersensitivity reactions. Non-toxic and non-irritating
Controls Personal protective equipment and increased ventilation. Personal protective equipment and increased ventilation. Personal protective equipment and increased ventilation. Personal protective equipment including goggles and increased ventilation. Ventilation. Personal protective equipment if sensitive. None.
Environ-mental Issues/ Disposal Toxic to aquatic organisms. Toxic to all animals including aquatic organisms. Remains persistent in the environment. Subject to disposal restrictions. Very toxic to aquatic organisms. Small amounts of dilute hydrogen peroxide can be flushed down a sink with a large quantity of water, unless local rules prohibit this. Larger amounts should be treated before disposal. None. Iodophors are highly toxic to aquatic life. Waste solutions may be discharged into sewers (subject to approval by the appropriate authority), where they will gradually be inactivated by proteins. None.
Additional Disadvantages Can cause damage to floor finishes, metals, carpets, clothing and other fibres at higher concentrations. Must be stored separately from ammonia and flammable products. Rinsing required in applications where direct skin or oral contact occurs (children’s toys). Inactivated in the presence of organic matter and by light and some metals. Not for use on food preparation surfaces or food utensils and in nurseries or crèches. May damage floor finishes and other surfaces. Leaves residue, rinsing required. Not effective against non-enveloped viruses such as norovirus and spores and some gram-negative bacteria. Can easily become contaminated. Not effective against C.difficile rotavirus and some gram-negative bacteria. Leaves residue, rinsing required. QUATs are generally inactivated by organic matter, detergents, soaps and hard water with the exception of newer, fourth generation QUATs. Rinsing required in applications where direct skin or oral contact occurs (children’s toys). 7.5% hydrogen peroxide can cause discoloration of black anodized metal finishes and bleaching of fabric. Cosmetic and functional material compatibility concerns with brass, zinc, copper, and nickel/silver plating. Inactivated by organic matter. Ineffective against Helicobacter and C. difficile. Can swell, harden and bleach rubber and certain plastic tubing and tiles after prolonged and repeated use. Activity limited in presence of organic matter. Highly flammable therefore must be stored in a cool ventilated area. Evaporates rapidly, making extended exposure time difficult to achieve unless the items are immersed. Activity reduced by high levels of organic matter. Can become contaminated therefore solutions need to be changed regularly. Cannot use other products in conjunction with iodophors. Not recommended for concrete surfaces. Expensive. Ineffective against some gram-negative bacteria. Equipment required to produce the product can be expensive because parameters such as pH, current, and redox potential must be closely monitored. Inactivated in presence of organic material.
Advantages Can remove biofilms and kill spores at high concentrations. Broad spectrum of antimicrobial activity. Does not leave toxic residues, unaffected by water hardness, inexpensive and fast acting. Readily available, maintains some activity in hard water and in the presence of organic matter and has some residual activity after drying. Readily available and does not cause damage to surfaces. Readily available, non-corrosive when diluted, no disposal issues, odour or irritation issues. Only chemical disinfectant able to inactivate C. parvum (at 6% and 7.5%). Retains similar bactericidal activity in the presence of organic matter. Stable over a wide pH range (pH 3–9), does not require exposure monitoring, non-staining and relatively free of toxicity. Retains some biocidal activity in the presence of organic matter. The solution is nontoxic to biologic tissues and non-corrosive to surfaces. Can remove biofilms at higher concentrations (>5% [v/v]).
Antimicrobial Activity Bactericidal, fungicidal, virucidal, tuberculocidal and sporicidal at high concentrations. Kills: M.tuberculosis, HBV, HAV, HIV at 1000ppm available chlorine, C. difficile at 5000 ppm in under 10 minutes, E. coli in 30seconds, H. pylori at 150 ppm in 30seconds, Norovirus at 1000ppm in 1min, SARS at 1000ppm in 1min, anthrax at 5250ppm in 5 mins, B. atrophaeus at 100ppm in 5 minutes, Candida and salmonella at 500ppm in 30seconds and P.aeruginosa in under 10 minutes. Bactericidal, fungicidal at 2%, virucidal, and tuberculocidal. Not sporicidal. Kills: HIV at 0.5% and Hydrophilic viruses at 5% in under 10 minutes. Generally fungicidal, bactericidal, and virucidal against lipophilic (enveloped) viruses. Not sporicidal and generally not tuberculocidal or virucidal against hydrophilic (nonenveloped) viruses. Kills: E. coli, H. pyloriS. aureus, vancomycin-resistant Entercoccus and P. Aeruginosa in 5 seconds. 7% stabilized hydrogen peroxideis sporicidal after 6 hours of exposure, mycobactericidal in 20 minutes, fungicidal in 5 minutes, virucidal in 5 minutes and bactericidal in 3 minutes at a 1:16 dilution. Kills: E. coli, Streptococcus and Pseudomonas species: 0.6% in 15 minutes, Norovirus at 5000ppm in 3 minutes, MRSA, VRE as a 3% spray, M.tuberculosis at 7.5% in 10 minutes, poliovirus and HAV 7.5% in 30 minutes and Cryptosporidium.

Bactericidal, tuberculocidal, fungicidal, and virucidal but not sporicidal. The optimum bactericidal concentration is 60%–90%. Kills:E. coli 30secs, H. pylori at 80% in 30secs, Rotavirus at 95%, Norovirus at 75% in 10min, SARS at 70% in 1min, Pseudomonas aeruginosa at 30% in 10sec, Salmonella at 40% in 10sec, MRSA at 60% in 10sec, M.tuberculosis at 95% in 15secs. At 60%: Herpes, vaccinia, influenza, adenovirus, enterovirus, rhinovirus, rotaviruses, HBV, HIV, echovirus, astrovirus. At 70%: Cryptococcus neoformans, Blastomyces dermatitidis, Coccidioides immitis, and Histoplasma capsulatum in 1-20 minutes. Bactericidal, mycobactericidal, and virucidal but can require prolonged contact times to kill certain fungi and not sporicidal. Kills: E. coli, S. aureus and M. chelonae at a 1:100 dilution in under 1 minute. Bactericidal, fungicidal, virucidal, tuberculocidal and sporicidal at high concentrations.
