If phenolics are used to terminally clean infant bassinets and incubators, the surfaces should be rinsed thoroughly with water and dried before reuse of infant bassinets and incubators 17. The U.S. Environmental Protection Agency is arming consumers with a list of disinfectants that people can use to protect themselves from the novel coronavirus. This defense is overwhelmed by the concentrations used for disinfection 653, 654. Two percent alkaline glutaraldehyde has slow action (20 to >30 minutes) against M. tuberculosis and compares unfavorably with alcohols, formaldehydes, iodine, and phenol 82. Always read and follow the directions on the label of cleaning and disinfection products to ensure safe and effective use. The quaternaries commonly are used in ordinary environmental sanitation of noncritical surfaces, such as floors, furniture, and walls. Glutaraldehyde is used most commonly as a high-level disinfectant for medical equipment such as endoscopes 69, 107, 504, spirometry tubing, dialyzers 616, transducers, anesthesia and respiratory therapy equipment 617, hemodialysis proportioning and dialysate delivery systems 249, 618, and reuse of laparoscopic disposable plastic trocars 619. For example, monitoring should be done initially to determine glutaraldehyde levels, after procedural or equipment changes, and in response to worker complaints 649. The passive badge, with a 0.02 ppm limit of detection, is considered marginal at the Americal Council of Governmental Industrial Hygienists (ACGIH) ceiling level. The concentration should be considered unacceptable or unsafe when the test indicates a dilution below the product’s minimum effective concentration (MEC) (generally to ≤1.0%–1.5% glutaraldehyde) by the indicator not changing color. The newer quaternary ammonium compounds (i.e., fourth generation), referred to as twin-chain or dialkyl quaternaries (e.g. Shares in listed unit Petronas … Sodium dichloroisocyanurate tablets are stable, and for two reasons, the microbicidal activity of solutions prepared from sodium dichloroisocyanurate tablets might be greater than that of sodium hypochlorite solutions containing the same total available chlorine. If OPA disposal through the sanitary sewer system is restricted, glycine (25 grams/gallon) can be used to neutralize the OPA and make it safe for disposal. The exact mechanism by which free chlorine destroys microorganisms has not been elucidated. Formaldehyde inactivates microorganisms by alkylating the amino and sulfhydral groups of proteins and ring nitrogen atoms of purine bases 376. The decline occurs because instruments are not thoroughly dried and water is carried in with the instrument, which increases the solution’s volume and dilutes its effective concentration 610. FDA has cleared a newer chemical sterilant with 0.23% peracetic acid and 7.35% hydrogen peroxide (Tables 4 and 5). An automated machine using peracetic acid to chemically sterilize medical (e.g., endoscopes, arthroscopes), surgical, and dental instruments is used in the United States716-718. Phenolics (and other disinfectants) should not be used to clean infant bassinets and incubators while occupied. The product marketed as a sterilant is a premixed, ready-to-use chemical that contains 7.5% hydrogen peroxide and 0.85% phosphoric acid (to maintain a low pH) 69. Iodophors formulated as antiseptics contain less free iodine than do those formulated as disinfectants 376. One study demonstrated little or no virucidal effect of a phenolic against coxsackie B4, echovirus 11, and poliovirus 1 736. Each compound exhibits its own antimicrobial characteristics, hence the search for one compound with outstanding antimicrobial properties. 3M makes this complex challenge simple with its wide array of chemical solutions … Manufacturer data demonstrated this combination of peracetic acid and hydrogen peroxide inactivated all microorganisms except bacterial spores within 20 minutes. Thus, if a user wished to have a solution containing 500 ppm of available chlorine at day 30, he or she should prepare a solution containing 1,000 ppm of chlorine at time 0. OPA appears to kill spores by blocking the spore germination process 691. Peracetic, or peroxyacetic, acid is characterized by rapid action against all microorganisms. Iodine can penetrate the cell wall of microorganisms quickly, and the lethal effects are believed to result from disruption of protein and nucleic acid structure and synthesis. It contains 0.55% 1,2-benzenedicarboxaldehyde (OPA). Testing can be done by four techniques: a silica gel tube/gas chromatography with a flame ionization detector, dinitrophenylhydrazine (DNPH)-impregnated filter cassette/high-performance liquid chromatography (HPLC) with an ultraviolet (UV) detector, a passive badge/HPLC, or a handheld glutaraldehyde air monitor 648. Ortho-phthalaldehyde is a high-level disinfectant that received FDA clearance in October 1999. A concentration of 100 ppm will kill ≥99.9% of B. atrophaeus spores within 5 minutes 541, 542 and destroy mycotic agents in <1 hour 329. As with any germicide, the antimicrobial activity of superoxidized water is strongly affected by the concentration of the active ingredient (available free chlorine) 536. Inclusion on List N does not constitute an endorsement by EPA. In experiments using the AOAC Use-Dilution Method, 100 ppm of free chlorine killed 106–107 S. aureus, Salmonella choleraesuis, and P. aeruginosa in <10 minutes 327. The guidance outlines a voluntary, pre-approval process for making emerging viral pathogens claims. One study showed a significant decline (~40%–50% lower at 1 hour) in the concentration of quaternaries released when cotton rags or cellulose-based wipers were used in the open-bucket system, compared with the nonwoven spunlace wipers in the closed-bucket system.744 As with several other disinfectants (e.g., phenolics, iodophors) gram-negative bacteria can survive or grow in them 404. (Tables 4 and 5). Other studies have found naturally occurring cells of P. aeurginosa were more resistant to a variety of disinfectants than were subcultured cells 705. They have a broad spectrum of antimicrobial activity, do not leave toxic residues, are unaffected by water hardness, are inexpensive and fast acting 328, remove dried or fixed organisms and biofilms from surfaces465, and have a low incidence of serious toxicity 515-517. EPA is providing this important information in a public and transparent manner on disinfectant products to help reduce the spread of COVID-19.”. Concentrations of hydrogen peroxide from 6% to 25% show promise as chemical sterilants. From windows to floors and stainless-steel surfaces, many chemicals are needed to ensure a facility is properly cleaned. It has excellent stability over a wide pH range (pH 3–9), is not a known irritant to the eyes and nasal passages 706, does not require exposure monitoring, has a barely perceptible odor, and requires no activation. OPA showed good activity against the mycobacteria tested, including the glutaraldehyde-resistant strains, but 0.5% OPA was not sporicidal with 270 minutes of exposure. One study reported that 25 different viruses were inactivated in 10 minutes with 200 ppm available chlorine 72. Chlorine dioxide can be produced by mixing solutions, such as a solution of chlorine with a solution of sodium chlorite 329. FDA has cleared a glutaraldehyde–phenol/phenate concentrate as a high-level disinfectant that contains 1.12% glutaraldehyde with 1.93% phenol/phenate at its use concentration. “Superoxidized water” has been tested against bacteria, mycobacteria, viruses, fungi, and spores 537, 539, 549. The percentage of dialysis centers using a peracetic acid-hydrogen peroxide-based disinfectant for reprocessing dialyzers increased from 5% in 1983 to 56% in 1997249. WASHINGTON (October 21, 2020) —The U.S. Environmental Protection Agency (EPA) has now approved more than 500 surface disinfectant products for use against SARS-CoV-2, the … These clusters highlight the importance of training, proper model-specific endoscope connector systems, and quality-control procedures to ensure compliance with endoscope manufacturer recommendations and professional organization guidelines. Sodium dichloroisocyanurate at 2,500 ppm available chlorine is effective against bacteria in the presence of up to 20% plasma, compared with 10% plasma for sodium hypochlorite at 2,500 ppm 548. Clinicians should not alter their use of chlorine on environmental surfaces on the basis of testing methodologies that do not simulate actual disinfection practices 560, 561. An iodophor is a combination of iodine and a solubilizing agent or carrier; the resulting complex provides a sustained-release reservoir of iodine and releases small amounts of free iodine in aqueous solution. Manufacturer data demonstrate that this solution sterilizes in 30 minutes and provides high-level disinfection in 5 minutes669. Peracetic acid will inactivate gram-positive and gram-negative bacteria, fungi, and yeasts in ≤5 minutes at <100 ppm. Inactivation of poliovirus in 10 minutes required an 8% concentration of formalin, but all other viruses tested were inactivated with 2% formalin 72. The high efficacy of the system was demonstrated in a comparison of the efficacies of the system with that of ethylene oxide. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. OPA, like glutaraldehyde, has excellent material compatibility. Hypochlorites are widely used in healthcare facilities in a variety of settings. The use of phenolics in nurseries has been questioned because of hyperbilirubinemia in infants placed in bassinets where phenolic detergents were used 739. Furthermore, three clusters of infection using the peracetic acid automated endoscope reprocessor were linked to inadequately processed bronchoscopes when inappropriate channel connectors were used with the system 725. This website … In 1964, Spaulding stated that alcohols were the germicide of choice for tuberculocidal activity, and they should be the standard by which all other tuberculocides are compared. In an automated endoscope reprocessor with an FDA-cleared capability to maintain solution temperatures at 25°C, the contact time for OPA is 5 minutes. If the manufacturer of the chemical test strip recommends a quality-control procedure, users should comply with the manufacturer’s recommendations. On the basis of these data and other studies, 20 minutes at room temperature is considered the minimum exposure time needed to reliably kill Mycobacteria and other vegetative bacteria with ≥2% glutaraldehyde 17, 19, 27, 57, 83, 94, 108, 111, 117-121, 607. In an investigation of 3%, 10%, and 15% hydrogen peroxide for reducing spacecraft bacterial populations, a complete kill of 106 spores (i.e., Bacillus species) occurred with a 10% concentration and a 60-minute exposure time. Saving Lives, Protecting People, Centers for Disease Control and Prevention, National Center for Emerging and Zoonotic Infectious Diseases (NCEZID), Division of Healthcare Quality Promotion (DHQP), Introduction, Methods, Definition of Terms, A Rational Approach to Disinfection and Sterilization, Factors Affecting the Efficacy of  Disinfection and Sterilization, Regulatory Framework for Disinfectants and Sterilants, Low-Temperature Sterilization Technologies, Microbicidal Activity of Low-Temperature Sterilization Technologies, Effect of Cleaning on Sterilization Efficacy, Recommendations for Disinfection and Sterilization in Healthcare Facilities, Table 1. Once activated, these solutions have a shelf-life of minimally 14 days because of the polymerization of the glutaraldehyde molecules at alkaline pH levels. EPA will update this list with additional … Sodium hypochlorite solution does not decompose after 30 days when stored in a closed brown bottle 327. getty. Hydrogen peroxide works by producing destructive hydroxyl free radicals that can attack membrane lipids, DNA, and other essential cell components. After reviewing environmental fate and ecologic data, EPA has determined the currently registered uses of hypochlorites will not result in unreasonable adverse effects to the environment 529. Other investigators have questioned the efficacy of iodophors against poliovirus in the presence of organic matter 685and rotavirus SA-11 in distilled or tapwater 290. Three brands of povidone-iodine solution have demonstrated more rapid kill (seconds to minutes) of S. aureus and M. chelonae at a 1:100 dilution than did the stock solution 683. Steripene II Brand Disinfectant Deodorant: Spartan Chemical Company Inc: … Their cidal activity drops sharply when diluted below 50% concentration, and the optimum bactericidal concentration is 60%–90% solutions in water (volume/volume) 483, 484. Peracetic acid can corrode copper, brass, bronze, plain steel, and galvanized iron but these effects can be reduced by additives and pH modifications. Hydrogen peroxide also has been instilled into urinary drainage bags in an attempt to eliminate the bag as a source of bladder bacteriuria and environmental contamination 675. If glutaraldehyde disposal through the sanitary sewer system is restricted, sodium bisulfate can be used to neutralize the glutaraldehyde and make it safe for disposal. Glutaraldehyde should not be used for cleaning noncritical surfaces because it is too toxic and expensive. With bacterial spores, 500–10,000 ppm (0.05%–1%) inactivates spores in 15 seconds to 30 minutes using a spore suspension test 654, 659, 713-715. The silica gel tube and the DNPH-impregnated cassette are suitable for monitoring the 0.05 ppm ceiling limit. The level of biocidal activity was directly related to the temperature. It has been used in concentrations from 3% to 6% for disinfecting soft contact lenses (e.g., 3% for 2–3 hrs) 653, 671, 672, tonometer biprisms 513, ventilators 673, fabrics 397, and endoscopes 456. A 1997 survey found that formaldehyde was used for reprocessing hemodialyzers by 34% of U.S. hemodialysis centers—a 60% decrease from 1983 249, 581. The difference in the recommended concentrations of bleach reflects the difficulty of cleaning the interior of needles and syringes and the use of needles and syringes for parenteral injection 559. First, with sodium dichloroisocyanurate, only 50% of the total available chlorine is free (HOCl and OCl–), whereas the remainder is combined (monochloroisocyanurate or dichloroisocyanurate), and as free available chlorine is used up, the latter is released to restore the equilibrium. However, skin staining would indicate improper handling that requires additional training and/or personal protective equipment (e.g., gloves, eye and mouth protection, and fluid-resistant gowns). This polymerization blocks the active sites (aldehyde groups) of the glutaraldehyde molecules that are responsible for its biocidal activity. Summary of advantages and disadvantages of chemical agents used as chemical sterilants or as high-level disinfectants, Table 6. Methyl alcohol (methanol) has the weakest bactericidal action of the alcohols and thus seldom is used in healthcare 488. In general, engineering controls are preferred over work-practice and administrative controls because they do not require active participation by the health-care worker. While making a chemist's guide to disinfectants is useful and helpful, a number of important chemical disinfectants was overlooked in the oxidizer category. A 10% hydrogen peroxide solution resulted in a 103 decrease in B. atrophaeus spores, and a ≥105 decrease when tested against 13 other pathogens in 30 minutes at 20°C 659, 660. In the healthcare setting, “alcohol” refers to two water-soluble chemical compounds—ethyl alcohol and isopropyl alcohol—that have generally underrated germicidal characteristics 482. As previously noted, dental handpieces should be steam sterilized. Published reports on the antimicrobial efficacy of commonly used phenolics showed they were bactericidal, fungicidal, virucidal, and tuberculocidal 14, 61, 71, 73, 227, 416, 573, 732-738. When the effectiveness of 7.5% hydrogen peroxide at 10 minutes was compared with 2% alkaline glutaraldehyde at 20 minutes in manual disinfection of endoscopes, no significant difference in germicidal activity was observed 668. FDA has not cleared any liquid chemical sterilant or high-level disinfectants with iodophors as the main active ingredient. Studies have demonstrated excellent microbicidal activity in vitro 69, 100, 271, 400, 692-703. Chemical Disinfectants Alcohol. In high concentrations, phenol acts as a gross protoplasmic poison, penetrating and disrupting the cell wall and precipitating the cell proteins. In the past 30 years, however, work has concentrated on the numerous phenol derivatives or phenolics and their antimicrobial properties. The standard includes a second permissible exposure limit in the form of a short-term exposure limit (STEL) of 2 ppm that is the maximum exposure allowed during a 15-minute period 576. The time required for inactivating three serotypes of rhinovirus using a 3% hydrogen peroxide solution was 6–8 minutes; this time increased with decreasing concentrations (18-20 minutes at 1.5%, 50–60 minutes at 0.75%). Get contact details & address of companies manufacturing and supplying Disinfectant Chemicals, Disinfectant Solution, Surface Disinfectant … Commercially available 3% hydrogen peroxide is a stable and effective disinfectant when used on inanimate surfaces. Catalase, produced by aerobic organisms and facultative anaerobes that possess cytochrome systems, can protect cells from metabolically produced hydrogen peroxide by degrading hydrogen peroxide to water and oxygen. Data suggest that 1.0%–1.5% glutaraldehyde is the minimum effective concentration for >2% glutaraldehyde solutions when used as a high-level disinfectant 76, 589, 590, 609. Glutaraldehyde is noncorrosive to metal and does not damage lensed instruments, rubber. For example, the toxic gas chlorine can be released if you mix sodium hypochlorite (bleaching solutions) and acidic cleaning agents. This is an emerging, rapidly evolving situation and the Centers for Disease Control and Prevention will provide updated information as it becomes available, in addition to updated guidance. Data are available for chlorine dioxide that support manufacturers’ bactericidal, fungicidal, sporicidal, tuberculocidal, and virucidal label claims 543-546. EPA-registered quaternary ammonium compounds are appropriate to use for disinfecting medical equipment that contacts intact skin (e.g., blood pressure cuffs). No functional damage or cosmetic changes occurred to the computer keyboards after 300 applications of the disinfectants 45. Manufacturers’ data using the standardized AOAC methods demonstrate that commercial phenolics are not sporicidal but are tuberculocidal, fungicidal, virucidal, and bactericidal at their recommended use-dilution. Formaldehyde is used as a disinfectant and sterilant in both its liquid and gaseous states. Chlorine dioxide-based disinfectants are prepared fresh as required by mixing the two components (base solution [citric acid with preservatives and corrosion inhibitors] and the activator solution [sodium chlorite]). This product and other iodophors retain the germicidal efficacy of iodine but unlike iodine generally are nonstaining and relatively free of toxicity and irritancy 677, 678. Decreasing order of resistance of microorganisms to disinfection and sterilization and the level of disinfection or sterilization, Table 4. Summary of advantages and disadvantages of commonly used sterilization technologies, Table 7. OPA has several potential advantages over glutaraldehyde. Disinfectants such as bleach clean contaminated surfaces by killing germs, so many scientists prefer to call those substances 'biocidal agents'.. Decontaminating … Chlorine long has been used as the disinfectant in water treatment. Iodine solutions or tinctures long have been used by health professionals primarily as antiseptics on skin or tissue. However, antimicrobial activity depends not only on age but also on use conditions, such as dilution and organic stress. An alternative high-level disinfectant available in the United Kingdom contains 0.35% peracetic acid. Isopropyl alcohol (20%) is effective in killing the cysts of Acanthamoeba culbertsoni (560) as are chlorhexidine, hydrogen peroxide, and thimerosal 496. Acute or chronic exposure can result in skin irritation or dermatitis, mucous membrane irritation (eye, nose, mouth), or pulmonary symptoms 318, 635-639. Additional studies are needed to determine whether this solution could be used as an alternative to other disinfectants or antiseptics for hand washing, skin antisepsis, room cleaning, or equipment disinfection (e.g., endoscopes, dialyzers) 400, 539, 540. The bottle of test strips should be dated when opened and used for the period of time indicated on the bottle (e.g., 120 days). Other studies demonstrated the antiviral activity of hydrogen peroxide against rhinovirus 665. Furthermore, OPA was effective over a 14-day use cycle 100. A 2.0% glutaraldehyde–7.05% phenol–1.20% sodium phenate product that contained 0.125% glutaraldehyde–0.44% phenol–0.075% sodium phenate when diluted 1:16 is not recommended as a high-level disinfectant because it lacks bactericidal activity in the presence of organic matter and lacks tuberculocidal, fungicidal, virucidal, and sporicidal activity 49, 55, 56, 71, 73-79, 614. When it is used, , direct exposure to employees generally is limited; however, excessive exposures to formaldehyde have been documented for employees of renal transplant units 574, 579, and students in a gross anatomy laboratory 580. Hydrogen peroxide is active against a wide range of microorganisms, including bacteria, yeasts, fungi, viruses, and spores 78, 654. Paraformaldehyde, a solid polymer of formaldehyde, can be vaporized by heat for the gaseous decontamination of laminar flow biologic safety cabinets when maintenance work or filter changes require access to the sealed portion of the cabinet. The virucidal activity of 75–150 ppm available iodine was demonstrated against seven viruses 72. Coronaviruses are enveloped viruses, meaning they are one of the easiest types of viruses to kill with the appropriate disinfectant product. These alcohols are rapidly bactericidal rather than bacteriostatic against vegetative forms of bacteria; they also are tuberculocidal, fungicidal, and virucidal but do not destroy bacterial spores. If engineering controls fail to maintain levels below the ceiling limit, institutions can consider the use of respirators (e.g., a half-face respirator with organic vapor cartridge 640 or a type “C” supplied air respirator with a full facepiece operated in a positive pressure mode) 651. For these reasons and others—such as its role as a suspected human carcinogen linked to nasal cancer and lung cancer 578, this germicide is excluded from Table 1. Products appearing on EPA’s list registered disinfectant products have qualified for use against COVID-19 through the agency’s Emerging Viral Pathogen program. o Bioesque Solutions Botanical Disinfectant Solution When phenol compounds are inhaled, ingested, or applied to the skin at high concentrations, the chemicals are harmful to humans. Similarly, 12% ortho-phenylphenol failed to inactivate any of the three hydrophilic viruses after a 10-minute exposure time, although 5% phenol was lethal for these viruses 72. The inclusion of acrylic resin particles in formulations markedly increases the volume of fluid that can be soaked up because the resin can absorb 200–300 times its own weight of fluid, depending on the fluid consistency. Two phenol derivatives commonly found as constituents of hospital disinfectants are ortho-phenylphenol and ortho-benzyl-para-chlorophenol. Several studies have demonstrated the effectiveness of diluted sodium hypochlorite and other disinfectants to inactivate HIV 61. No complaints were received from the nursing or medical staff regarding odor or toxicity. The documented shortcomings of alcohols on equipment are that they damage the shellac mountings of lensed instruments, tend to swell and harden rubber and certain plastic tubing after prolonged and repeated use, bleach rubber and plastic tiles 482 and damage tonometer tips (by deterioration of the glue) after the equivalent of 1 working year of routine use 512. 416, 737 iodine-based antiseptics should not be used for illicit-drug injection when needle-exchange programs not.
