What is the unique characteristic of an ortho Phthalaldehyde?
OPA has several potential advantages compared with glutaraldehyde. It has excellent stability over a wide pH range (pH 3 to 9), is not a known irritant to the eyes and nasal passages, does not require exposure monitoring, has a barely perceptible odor, and requires no activation.
What is intermediate disinfection?
Intermediate-level disinfection refers to the use of an agent that kills a wider range of pathogens than a low-level disinfectant but does not kill bacterial spores. EPA-registered hospital disinfectants with a tuberculocidal claim are intermediate-level disinfectants.
What is cidex sterilization?
Cidex® Activated Dialdehyde solution is a fast and effective way to disinfect and sterilize a wide variety of medical devices and instruments. Cidex 14 day use, a 2.4% alkaline glutaraldehyde solution, destroys 99.8% of Mycobacterium tuberculosis in 45 minutes at 25 degrees Celsius.

Is isopropyl alcohol a low-level disinfectant?
Isopropyl alcohol is excluded from classification as a high-level disinfectant because of its inability to eradicate bacterial spores and hydrophilic viruses such as polio. Its low-level categorization outlines effectiveness for noncritical patient care devices such as blood pressure cuffs.
When did ortho phthalaldehyde get FDA clearance?
William A. Rutala, David J. Webe, University of North Carolina (UNC) Health Care System and UNC School of Medicine, Chapel Hill, North Carolina, USA. Ortho-phthalaldehyde (OPA) received clearance by FDA in October 1999. OPA solution is a clear, pale-blue liquid (pH, 7.5), which typically contains 0.55% OPA.
Which is better for sterilization OPA or glutaraldehyde?
Increasing the pH from its unadjusted level (about 6.5) to pH 8 improved sporicidal activity. OPA has several potential advantages compared with glutaraldehyde.
What is the name of the new sterilization agent?
Ortho-phthalaldehyde: a New Chemical Sterilant Ortho-phthalaldehyde (OPA) received clearance by FDA in October 1999. OPA solution is a clear, pale-blue liquid (pH, 7.5), which typically contains 0.55% OPA. OPA has demonstrated excellent microbiocidal activity in in vitro studies [ 2, 3].
What are some of the new disinfection methods?
New disinfection methods include a persistent antimicrobial-drug coating that can be applied to inanimate and animate objects (Surfacine), a high-level disinfectant with reduced exposure time (ortho-phthalaldehyde), and an antimicrobial drug that can be applied to animate and inanimate objects (superoxidized water).
