Freshly generated superoxidized water is rapidly effective (<2 minutes) in achieving a 5-log10 reduction of pathogenic microorganisms (i.e., M. tuberculosis, M. chelonae, poliovirus, HIV, multidrug-resistant S. aureus, E. coli, Candida albicans, Enterococcus faecalis, P. aeruginosa) in the absence of organic loading. Peracetic acid (0.26%) was effective (log10 reduction factor >5) against all test strains of mycobacteria (M. tuberculosis, M. avium-intracellulare, M. chelonae, and M. fortuitum) within 20–30 minutes in the presence or absence of an organic load 607, 712. Aerosol Disinfectants / Sanitizers. Disinfectants are chemical agents designed to inactivate or destroy microorganisms on inert surfaces. Comments: Viracide is manufactured using the WHO recommended formulation. 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. Disinfectants / Sanitizers. This is called “dwell time” and should be taken into account when choosing and using sanitizers and disinfectants for various applications. The 0.08% peracetic acid plus 1.0% hydrogen peroxide product effectively inactivated glutaraldehyde-resistant mycobacteria729. Disinfectants, antiseptics and sanitizers are all chemical substances that kill microorganisms. 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. 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. The high-level disinfectant label claims for OPA solution at 20°C vary worldwide (e.g., 5 minutes in Europe, Asia, and Latin America; 10 minutes in Canada and Australia; and 12 minutes in the United States). A chlorine dioxide generator has been shown effective for decontaminating flexible endoscopes 534 but it is not currently FDA-cleared for use as a high-level disinfectant 85. 99,9% kills within contact. 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. 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. Phenol derivatives originate when a functional group (e.g., alkyl, phenyl, benzyl, halogen) replaces one of the hydrogen atoms on the aromatic ring. Characteristics of an ideal low-temperature sterilization process, Table 10. Aerosol Disinfectants / Sanitizers. To minimize a potential health hazard to dialysis patients, the dialysis equipment must be thoroughly rinsed and tested for residual formaldehyde before use. 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. In another study, chlorine dioxide solutions at either 600 ppm or 30 ppm killed Mycobacterium avium-intracellulare within 60 seconds after contact but contamination by organic material significantly affected the microbicidal properties535. Thirty minutes were required for >99.9% inactivation of poliovirus and HAV 667. Precision Chemical & … The product generated has a pH of 5.0–6.5 and an oxidation-reduction potential (redox) of >950 mV. Disinfectant Wipes. In tests of the effect of ethyl alcohol against M. tuberculosis, 95% ethanol killed the tubercle bacilli in sputum or water suspension within 15 seconds 492. Effectively cleans, disinfects and sanitizes to reduce the hazards of cross infection on hard surfaces. (Tables 4 and 5) The FDA website lists cleared liquid chemical sterilants and high-level disinfectants containing hydrogen peroxide and their cleared contact conditions. For example, alkaline detergents more efficiently remove fat- and protein-based soils, while mineral-based soils require acid cleaners. 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. Because household bleach contains 5.25%–6.15% sodium hypochlorite, or 52,500–61,500 ppm available chlorine, a 1:1,000 dilution provides about 53–62 ppm available chlorine, and a 1:10 dilution of household bleach provides about 5250–6150 ppm. Iodine solutions or tinctures long have been used by health professionals primarily as antiseptics on skin or tissue. Liquid Disinfectants / Sanitizers. Peracetic acid can corrode copper, brass, bronze, plain steel, and galvanized iron but these effects can be reduced by additives and pH modifications. Therefore, iodophors must be diluted according to the manufacturers’ directions to achieve antimicrobial activity. 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. Inactivation of poliovirus in 10 minutes required an 8% concentration of formalin, but all other viruses tested were inactivated with 2% formalin 72. The EPA Reg. 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. Full-strength bleach has been recommended for self-disinfection of needles and syringes used for illicit-drug injection when needle-exchange programs are not available. One example is quaternary ammonia based products. 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. Disinfectant Wipes. Comments: ViraFog is a strongly cationic product and therefore incompatible with formulations containinganionic compounds. However, spores do have a resistance to hypochlorites because their outer coat is not susceptible to the strong oxidizing nature of the chemical. During this time of the Covid-19 pandemic Maryland Chemical is here for you and has many sanitizing and disinfecting solutions available to meet your needs. OPA must be disposed in accordance with local and state regulations. This is called “dwell time” and should be taken into account when choosing and using sanitizers and disinfectants for various applications. Liquid Disinfectants / Sanitizers Clean Innovations 575 E. Eleventh Ave. Columbus, OH 43211 (phone) 614-299-1187 (fax) 614-299-2011 Disinfectants / Sanitizers | Chemicals | Clean Innovations This mechanism is supported by the observation that absolute ethyl alcohol, a dehydrating agent, is less bactericidal than mixtures of alcohol and water because proteins are denatured more quickly in the presence of water 484, 485. Under normal conditions, hydrogen peroxide is extremely stable when properly stored (e.g., in dark containers). OPA has several potential advantages over glutaraldehyde. An epidemic of pseudomembrane-like enteritis and colitis in seven patients in a gastrointestinal endoscopy unit also has been associated with inadequate rinsing of 3% hydrogen peroxide from the endoscope 676. A 3% concentration for 150 minutes killed 106 spores in six of seven exposure trials 658. Although this product is rapidly effective against a broad range of microorganisms 466, 726, 727, it tarnishes the metal of endoscopes and is unstable, resulting in only a 24-hour use life 727. Chlorine long has been used as the disinfectant in water treatment. Isopropyl alcohol (20%) is effective in killing the cysts of Acanthamoeba culbertsoni (560) as are chlorhexidine, hydrogen peroxide, and thimerosal 496. As an example, Table Time 200 eliminates 99.999% of bacteria* in 1 minute. Glutaraldehyde is noncorrosive to metal and does not damage lensed instruments, rubber. At least 500 ppm available chlorine for 10 minutes is recommended for decontaminating CPR training manikins 558. (Tables 4 and 5). Bacterial endospores are most resistant to disinfectants, however some viruses and bacteria also possess some tolerance. Meticulous cleaning, using the correct OPA exposure time (e.g., 12 minutes) and copious rinsing of the probe with water should eliminate this problem. Search. Comparative evaluation of the microbicidal activity of low-temperature sterilization technology of carriers sterilized by various low-temperature sterilization technologies, Table 12. 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… Although the instillation of hydrogen peroxide into the bag reduced microbial contamination of the bag, this procedure did not reduce the incidence of catheter-associated bacteriuria 675. Quaternary ammonium compounds (as well as 70% isopropyl alcohol, phenolic, and a chlorine-containing wipe [80 ppm]) effectively (>95%) remove and/or inactivate contaminants (i.e., multidrug-resistant S. aureus, vancomycin-resistant Entercoccus, P. aeruginosa) from computer keyboards with a 5-second application time.

An investigation that compared the costs, performance, and maintenance of urologic endoscopic equipment processed by high-level disinfection (with glutaraldehyde) with those of the peracetic acid system reported no clinical differences between the two systems. A new, rapid-acting 13.4% hydrogen peroxide formulation (that is not yet FDA-cleared) has demonstrated sporicidal, mycobactericidal, fungicidal, and virucidal efficacy. Inactivation by chlorine can result from a number of factors: oxidation of sulfhydryl enzymes and amino acids; ring chlorination of amino acids; loss of intracellular contents; decreased uptake of nutrients; inhibition of protein synthesis; decreased oxygen uptake; oxidation of respiratory components; decreased adenosine triphosphate production; breaks in DNA; and depressed DNA synthesis 329, 347. 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 results of test strip monitoring should be documented. Methods of sterilization and disinfection, Table 2. Ortho-phthalaldehyde is a high-level disinfectant that received FDA clearance in October 1999. The use of phenolics in nurseries has been questioned because of hyperbilirubinemia in infants placed in bassinets where phenolic detergents were used 739. CONCENTRATION OF CHEMICAL USED Sanitizers are used at much lower concentrations than the concentrations used for disinfectants. Login; Janitorial Supplies 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). Disinfectant Wipes. MCS Sanitation Dieppe In addition, bilirubin levels were reported to increase in phenolic-exposed infants, compared with nonphenolic-exposed infants, when the phenolic was prepared according to the manufacturers’ recommended dilution 740. No. Aerosol Disinfectants / Sanitizers. The high efficacy of the system was demonstrated in a comparison of the efficacies of the system with that of ethylene oxide. 820 Martin Luther King Jr Blvd Macon, GA 31201. 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. However, two studies found no difference in the microbicidal activity of alkaline and acid glutaraldehydes 73, 591. The main products of this water are hypochlorous acid (e.g., at a concentration of about 144 mg/L) and chlorine. Comments: Virasurf is a strongly cationic product and therefore incompatible with formulations containinganionic compounds. Before using any chemical, read the product label and manufacturer’s material safety data sheet. In the healthcare setting, “alcohol” refers to two water-soluble chemical compounds—ethyl alcohol and isopropyl alcohol—that have generally underrated germicidal characteristics 482. M. chelonae persisted in a 0.2% glutaraldehyde solution used to store porcine prosthetic heart valves 604. Iodophors, on the other hand, have been used both as antiseptics and disinfectants. Waterless hand sanitizer. The dissociation of HOCI to the less microbicidal form (hypochlorite ion OCl‑) depends on pH. If phenolics are used to clean nursery floors, they must be diluted as recommended on the product label. 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. One study reported that 25 different viruses were inactivated in 10 minutes with 200 ppm available chlorine 72. Hypochlorites are widely used in healthcare facilities in a variety of settings.
