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]). In December 1991, EPA issued an order to stop the sale of all batches of this product because of efficacy data showing the product is not effective against spores and possibly other microorganisms or inanimate objects as claimed on the label 615. (Tables 4 and 5) The FDA website lists cleared liquid chemical sterilants and high-level disinfectants containing hydrogen peroxide and their cleared contact conditions. Simulated-use trials have demonstrated excellent microbicidal activity 111, 718-722, and three clinical trials have demonstrated both excellent microbial killing and no clinical failures leading to infection90, 723, 724. Iodophors, on the other hand, have been used both as antiseptics and disinfectants. In addition, equipment must be thoroughly rinsed to prevent discoloration of a patient’s skin or mucous membrane. 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. No functional damage or cosmetic changes occurred to the computer keyboards after 300 applications of the disinfectants 45. The bactericidal properties of peracetic acid and hydrogen peroxide have been demonstrated 728. To minimize a potential health hazard to dialysis patients, the dialysis equipment must be thoroughly rinsed and tested for residual formaldehyde before use. 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. Manufacturer data show that OPA will last longer in an automatic endoscope reprocessor before reaching its MEC limit (MEC after 82 cycles) than will glutaraldehyde (MEC after 40 cycles) 400. Properties of an ideal disinfectant, Table 3. 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. However, test results have varied extensively among laboratories testing identical products 416, 737. Novel glutaraldehyde formulations (e.g., glutaraldehyde-phenol-sodium phenate, potentiated acid glutaraldehyde, stabilized alkaline glutaraldehyde) produced in the past 30 years have overcome the problem of rapid loss of activity (e.g., use-life 28–30 days) while generally maintaining excellent microbicidal activity 584-588. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. 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. Formaldehyde is sold and used principally as a water-based solution called formalin, which is 37% formaldehyde by weight. Suggested protocol for management of positive biological indicator in a steam sterilizer, U.S. Department of Health & Human Services. Businesses across the U.S. have begun intensive Covid-19 disinfection regimens, exposing returning workers and consumers to some chemicals that are largely untested for human … 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. Only when the solution is “activated” (made alkaline) by use of alkalinating agents to pH 7.5–8.5 does the solution become sporicidal. Tonometer biprisms soaked in alcohol for 4 days developed rough front surfaces that potentially could cause corneal damage; this appeared to be caused by weakening of the cementing substances used to fabricate the biprisms 513. A 1:10–1:100 dilution of 5.25%–6.15% sodium hypochlorite (i.e., household bleach) 22, 228, 553, 554 or an EPA-registered tuberculocidal disinfectant 17has been recommended for decontaminating blood spills. Hydrogen peroxide was effective in spot-disinfecting fabrics in patients’ rooms 397. However, two studies found no difference in the microbicidal activity of alkaline and acid glutaraldehydes 73, 591. The newer quaternary ammonium compounds (i.e., fourth generation), referred to as twin-chain or dialkyl quaternaries (e.g. The ceiling level is considered too close to the glutaraldehyde meter’s 0.03 ppm limit of detection to provide confidence in the readings 648. OPA must be disposed in accordance with local and state regulations. No bacteria or viruses were detected on artificially contaminated endoscopes after a 5-minute exposure to superoxidized water 551 and HBV-DNA was not detected from any endoscope experimentally contaminated with HBV-positive mixed sera after a disinfectant exposure time of 7 minutes552. This product is not currently available. Author: EPA, Office of Policy, Registration of Disinfectants Pesticides. 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. Varying concentrations of aqueous formaldehyde solutions destroy a wide range of microorganisms. However, results from these same studies have varied dramatically among laboratories testing identical products. Hydrogen peroxide works by producing destructive hydroxyl free radicals that can attack membrane lipids, DNA, and other essential cell components. 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. The mycobactericidal activity of 7.5% hydrogen peroxide has been corroborated in a study showing the inactivation of >105 multidrug-resistant M. tuberculosis after a 10-minute exposure 666. Ortho-phthalaldehyde is a high-level disinfectant that received FDA clearance in October 1999. In high concentrations, phenol acts as a gross protoplasmic poison, penetrating and disrupting the cell wall and precipitating the cell proteins. The aqueous solution is a bactericide, tuberculocide, fungicide, virucide and sporicide 72, 82, 571-573. One study found that residual glutaraldehyde levels were higher and more variable after manual disinfection (<0.2 mg/L to 159.5 mg/L) than after automatic disinfection (0.2–6.3 mg/L)631. Steripene II Brand Disinfectant Deodorant: Spartan Chemical Company Inc: … Characteristics of an ideal low-temperature sterilization process, Table 10. The mean times required to produce a 6-log10 reduction for M. bovis using 0.21% OPA was 6 minutes, compared with 32 minutes using 1.5% glutaraldehyde 693. Use chemical disinfectants safely! Two phenol derivatives commonly found as constituents of hospital disinfectants are ortho-phenylphenol and ortho-benzyl-para-chlorophenol. Contact Us to ask a question, provide feedback, or report a problem. An FDA-cleared chemical sterilant containing 2.5% glutaraldehyde uses increased temperature (35°C) to reduce the time required to achieve high-level disinfection (5 minutes) 85, 606, but its use is limited to automatic endoscope reprocessors equipped with a heater.
