Iodine or iodine-based antiseptics should not be used on silicone catheters because they can adversely affect the silicone tubing 687. The combination of peracetic acid and hydrogen peroxide has been used for disinfecting hemodialyzers 730. 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. No. If phenolics are used to clean nursery floors, they must be diluted as recommended on the product label. Formaldehyde is used in the health-care setting to prepare viral vaccines (e.g., poliovirus and influenza); as an embalming agent; and to preserve anatomic specimens; and historically has been used to sterilize surgical instruments, especially when mixed with ethanol. Liquid Disinfectants / Sanitizers. Acidified bleach and regular bleach (5,000 ppm chlorine) can inactivate 106 Clostridium difficile spores in ≤10 minutes 262. These are microscopic organisms, like bacteria and viruses. A few OPA clinical studies are available. These products are for use on surfaces, not humans. Other studies demonstrated the antiviral activity of hydrogen peroxide against rhinovirus 665. 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. 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. 2112 W. Washington Street Stephenville, TX 76401. Children should not use these products. The virucidal activity of 75–150 ppm available iodine was demonstrated against seven viruses 72. An alternative high-level disinfectant available in the United Kingdom contains 0.35% peracetic acid. The influence of laboratory adaptation of test strains, such as P. aeruginosa, to 0.55% OPA has been evaluated. A chemical irritation resembling pseudomembranous colitis caused by either 3% hydrogen peroxide or a 2% glutaraldehyde has been reported 621. EPA registered and FDA approved as a disinfectant against the Coronavirus. Although the United Kingdom manufacturer claims the solution is noncorrosive and nondamaging to endoscopes and processing equipment, one flexible endoscope manufacturer (Olympus Key-Med, United Kingdom) has voided the warranty on the endoscopes if superoxidized water is used to disinfect them 538. One study reported that 25 different viruses were inactivated in 10 minutes with 200 ppm available chlorine 72. A potential hazard is production of the carcinogen bis(chloromethyl) ether when hypochlorite solutions contact formaldehyde 527 and the production of the animal carcinogen trihalomethane when hot water is hyperchlorinated 528. However, efficacy did not differ when the exposure time was ≥10 minutes 697. Read our step-by-step guide. The bactericidal properties of peracetic acid and hydrogen peroxide have been demonstrated 728. Key provisions of the OSHA standard that protects workers from exposure to formaldehyde appear in Title 29 of the Code of Federal Regulations (CFR) Part 1910.1048 (and equivalent regulations in states with OSHA-approved state plans) 577. As an example, quaternary ammonium compounds are used at 200 ppm as sanitizers, but anywhere from 600 to 2100 ppm as disinfectants. of a product for primary registrants consists of two sets of numbers separated by a hyphen (for example, EPA Reg. Hypochlorite solutions in tap water at a pH >8 stored at room temperature (23°C) in closed, opaque plastic containers can lose up to 40%–50% of their free available chlorine level over 1 month. FDA has not cleared any liquid chemical sterilant or high-level disinfectant with alcohol as the main active ingredient. Sanitizers are high level disinfectants that kill over 99.9% of a target microorganism in applicable situations. Use of the listed EPA-registered products consistent with the product labeling complies with the Occupational Safety and Health Administration‘s requirements for Occupational Exposure to blood born… … Aerosol Disinfectants / Sanitizers. Liquid Disinfectants / Sanitizers. Synergistic sporicidal effects were observed when spores were exposed to a combination of hydrogen peroxide (5.9%–23.6%) and peracetic acid 664. Other uses in healthcare include as an irrigating agent in endodontic treatment 562 and as a disinfectant for manikins, laundry, dental appliances, hydrotherapy tanks 23, 41, regulated medical waste before disposal 328, and the water distribution system in hemodialysis centers and hemodialysis machines 563. Health-care–associated infections have been reported from contaminated quaternary ammonium compounds used to disinfect patient-care supplies or equipment, such as cystoscopes or cardiac catheters 741, 742. Three percent and 6% hydrogen peroxide were unable to inactivate HAV in 1 minute in a carrier test 58. The most feasible explanation for the antimicrobial action of alcohol is denaturation of proteins. All disinfectants that have a drug identification number (DIN) have been approved for sale in Canada. Ethyl alcohol, at concentrations of 60%–80%, is a potent virucidal agent inactivating all of the lipophilic viruses (e.g., herpes, vaccinia, and influenza virus) and many hydrophilic viruses (e.g., adenovirus, enterovirus, rhinovirus, and rotaviruses but not hepatitis A virus (HAV) 58 or poliovirus) 49. 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. For example, EPA requires manufacturers of sanitizers, disinfectants, or chemical sterilants to test formulations by using accepted methods for microbiocidal activity, stability, and toxicity to animals and humans. Disinfectants / Sanitizers. The bactericidal activity of various concentrations of ethyl alcohol (ethanol) was examined against a variety of microorganisms in exposure periods ranging from 10 seconds to 1 hour 483. Username: Password: Login New Account. In another study employing membrane filters for measurement of mycobactericidal activity of 2% alkaline glutaraldehyde, complete inactivation was achieved within 20 minutes at 20°C when the test inoculum was 106 M. tuberculosis per membrane 81. Two chemical sterilants are available that contain peracetic acid plus hydrogen peroxide (i.e., 0.08% peracetic acid plus 1.0% hydrogen peroxide [no longer marketed]; and 0.23% peracetic acid plus 7.35% hydrogen peroxide (Tables 4 and 5). Liquid Disinfectants / Sanitizers . For example, monitoring should be done initially to determine glutaraldehyde levels, after procedural or equipment changes, and in response to worker complaints 649. Aqueous solutions of glutaraldehyde are acidic and generally in this state are not sporicidal. For example, there are sanitizing rinses for surfaces such as dishes and cooking utensils as well as sanitizers for cooking surfaces. Corneal opacification has been reported when tonometer tips were swabbed with alcohol immediately before measurement of intraocular pressure 514. Indication: Ready to use Surface Disinfectant. FDA has not cleared any liquid chemical sterilant or high-level disinfectants with iodophors as the main active ingredient. 99,9% kills within contact. How it Works: Antimicrobial action of alcohol is denaturation of proteins. No. The action of Viracide is against the envelope of the virus. In one study, 3.5% peracetic acid was ineffective against HAV after 1-minute exposure using a carrier test 58. Under normal conditions, hydrogen peroxide is extremely stable when properly stored (e.g., in dark containers). 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. ... Disinfectants / Sanitizers. | Memphis, TN 38118 | 800.400.1928 | F: 901.363.7839 firstname.lastname@example.org Bacterial endospores are most resistant to disinfectants, however some viruses and bacteria also possess some tolerance. 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. Chemical germicides used for decontamination range in activity from high-level disinfectants (i.e., high concentrations of sodium hypochlorite [chlorine bleach]), which might be used to decontaminate spills of cultured or concentrated infectious agents in research or clinical laboratories, to low-level disinfectants or sanitizers for general housekeeping purposes or spot decontamination of … Effectively cleans, disinfects and sanitizes to reduce the hazards of cross infection on hard surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life. For these reasons, employees should have limited direct contact with formaldehyde, and these considerations limit its role in sterilization and disinfection processes. Chemicals; Disinfectants / Sanitizers; Disinfectants / Sanitizers. A 0.5% dilution of a phenolic (2.8% ortho-phenylphenol and 2.7% ortho-benzyl-para-chlorophenol) inactivated HIV 227 and a 2% solution of a phenolic (15% ortho-phenylphenol and 6.3% para-tertiary-amylphenol) inactivated all but one of 11 fungi tested 71. Alternative compounds that release chlorine and are used in the health-care setting include demand-release chlorine dioxide, sodium dichloroisocyanurate, and chloramine-T.

Application Area: Offices, work areas, walls, floors in operating rooms, wash rooms, locker and medical rooms. As an example, Table Time 200 eliminates 99.999% of bacteria* in 1 minute. Although superoxidized water is intended to be generated fresh at the point of use, when tested under clean conditions the disinfectant was effective within 5 minutes when 48 hours old 537. Preventive measures include removal of OPA residues by thorough rinsing and not using OPA for reprocessing urologic instrumentation used to treat patients with a history of bladder cancer (Nevine Erian, personal communication, June 4, 2004; Product Notification, Advanced Sterilization Products, April 23, 2004) 709. Ethyl alcohol (70%) was the most effective concentration for killing the tissue phase of Cryptococcus neoformans, Blastomyces dermatitidis, Coccidioides immitis, and Histoplasma capsulatum and the culture phases of the latter three organisms aerosolized onto various surfaces. Air disinfectants are often glycols, such as propylene glycol or triethylene glycol. TOPMOST CHEMICAL & PAPER | 3394 Winchester Rd. The poor mycobactericidal activities of quaternary ammonium compounds have been demonstrated 55, 73. Olympus America does not endorse use of 0.08% peracetic acid plus 1.0% hydrogen peroxide (Olympus America, personal communication, April 15, 1998) on any Olympus endoscope because of cosmetic and functional damage and will not assume liability for chemical damage resulting from use of this product. Inclusion on List N does not constitute an endorsement by EPA. To ensure the presence of minimum effective concentration of the high-level disinfectant, manufacturers of some chemical test strips recommend the use of quality-control procedures to ensure the strips perform properly. This is compensated for by the lipophilic aromatic nature of OPA that is likely to assist its uptake through the outer layers of mycobacteria and gram-negative bacteria 688-690. Characteristics of an ideal low-temperature sterilization process, Table 10. Sodium hypochlorite at the concentration used in household bleach (5.25-6.15%) can produce ocular irritation or oropharyngeal, esophageal, and gastric burns 318, 518-522. Aerosol Disinfectants / Sanitizers. Pseudomonas aeruginosa was killed in 10 seconds by all concentrations of ethanol from 30% to 100% (v/v), and Serratia marcescens, E, coli and Salmonella typhosa were killed in 10 seconds by all concentrations of ethanol from 40% to 100%. For example, he compared the tuberculocidal activity of iodophor (450 ppm), a substituted phenol (3%), and isopropanol (70%/volume) using the mucin-loop test (106 M. tuberculosis per loop) and determined the contact times needed for complete destruction were 120–180 minutes, 45–60 minutes, and 5 minutes, respectively. 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. Four percent formaldehyde is a tuberculocidal agent, inactivating 104 M. tuberculosis in 2 minutes 82, and 2.5% formaldehyde inactivated about 107 Salmonella Typhi in 10 minutes in the presence of organic matter 572. Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite). Of approximately 1 million urologic procedures performed using instruments reprocessed using OPA, 24 cases (17 cases in the United States, six in Japan, one in the United Kingdom) of anaphylaxis-like reactions have been reported after repeated cystoscopy (typically after four to nine treatments). It remains effective in the presence of organic matter and is sporicidal even at low temperatures (Tables 4 and 5). In addition, equipment must be thoroughly rinsed to prevent discoloration of a patient’s skin or mucous membrane. All chemical disinfectants are, by their very nature, potentially harmful or toxic to living organisms. They also evaporate rapidly, making extended exposure time difficult to achieve unless the items are immersed. Glutaraldehyde is commonly diluted during use, and studies showed a glutaraldehyde concentration decline after a few days of use in an automatic endoscope washer 608, 609.
