Intended Use
ACECIDE-C is a high level disinfectant intended to disinfect reusable clean heatsensitive semi-critical medical devices (such as flexible endoscopes) which contact mucous membranes when used at or above its minimum recommended concentration of 2000 ppm peracetic acid for 7.0 minutes at 20°C. ACECIDE-C is a sterilant intended to sterilize reusable clean heat-sensitive critical and semi-critical medical devices (such as flexible endoscopes) which contact and potentially penetrate into sterile body areas, for which there is no other practical method of sterilization, when used at or above its minimum recommended concentration of 2000 ppm peracetic acid for 2.0 hours at 20℃. ACECIDE Test Strips are used with ACECIDE-C High Level Disinfectant and Sterilant use solution to ensure that the level of peracetic acid is above the minimum recommended concentration of 2000 ppm.
Device Story
ACECIDE-C is a two-part liquid chemical system (peracetic acid concentrate and buffer concentrate) mixed with tap water at point-of-use to generate a peracetic acid solution (3100-3400 ppm). Used in clinical settings for high-level disinfection (7 minutes at 20°C) or sterilization (2 hours at 20°C) of heat-sensitive medical devices like flexible endoscopes. Operators use ACECIDE Test Strips to verify peracetic acid concentration remains above 2000 ppm before each use. The test strips utilize a colorimetric reaction (iodide to iodine with starch) to provide visual confirmation of efficacy. The device provides an alternative sterilization method for devices where other methods are impractical, ensuring patient safety by eliminating microbial contamination on reusable instruments.
Clinical Evidence
No clinical trials; evidence based on extensive bench testing. Studies included AOAC Use Dilution (955.14, 955.15, 964.02), Fungicidal (955.17), and Sporicidal (966.04) tests. Results confirmed 100% disinfection of bacterial-labeled cylinders and complete kill of fungi, viruses (Influenza A, HSV-1, Adenovirus, Poliovirus), and M. terrae. Simulated-use testing on bronchoscopes, gastroscopes, and colonoscopes demonstrated >6 log10 reduction of M. terrae and B. subtilis. In-use testing at clinical sites showed zero bacterial recovery from endoscopes after processing.
Technological Characteristics
Two-part liquid chemical system: Solution 1 (acetic acid, hydrogen peroxide, catalyst, stabilizer) and Solution 2 (sequestrant, anti-corrosive, buffer salts). Mixed 1:1:18 with tap water. Active ingredient: peracetic acid (3100-3400 ppm). Final pH 3.4-3.7. Uses colorimetric test strips for concentration verification. Non-electronic, chemical-based disinfection/sterilization.
Indications for Use
Indicated for high-level disinfection or sterilization of reusable, clean, heat-sensitive critical and semi-critical medical devices, including flexible endoscopes, that contact mucous membranes or penetrate sterile body areas.
Regulatory Classification

and Acecide contains concentrations of the chemicals that react to produce peracetic acid (hydrogen peroxide and acetic acid) at low pH values of about 1.0 or less. ACECIDE-C Solution 2 is a concentrated buffer solution, while Acecide Solution 2 is a dilute buffer solution. The mixed use solutions contain antimicrobial concentrations of 3100 to 3800 ppm peracetic acid. ACECIDE-C has a final pH value of about 3.4 to 3.7 and Acecide has a final pH value of about 4.0 to 4.5. Both of these products are intended for the high-level disinfection and/or sterilization of clean. heat-sensitive devices for which there is no other practical method for disinfection or sterilization. Acecide is a legally marketed sterilant. For these reasons, Acecide is an appropriate predicate device for comparisons of substantial equivalence to ACECIDE-C.

- h. Summary of the technological characteristics of ACECIDE -C High-Level Disinfectant and Sterilant as Compared with the Predicate, Acecide High-Level Disinfectant and Sterilant.
- ACECIDE-C High-Level Disinfectant and Sterilant and Acecide High-Level i. Disinfectant and Sterilant contain similar concentrations of peracetic acid as an active ingredient, and the use dilution of each are similar. The Acecide use dilution is about 3300 to 3800 ppm peracetic acid and gradually declines through five days of use and re-use at 25°C until its concentration decreases to 1900 ppm peracetic acid. The use dilution of ACECIDE-C starts at 3100 to 3400 ppm peracetic acid and gradually declines through five days of use and re-use at 20°C until its concentration decreases to 2000 pom peracetic acid. In eight separate five day EPA Re-Use Tests at 20°C, the concentration of peracetic acid in ACECIDE-C never decreased below 2000 ppm before the conclusion of each study.

#### Summary description of in-use tests with ACECIDE-C. i.
Olympus gastroscopes and colonoscopes as received directly from patients at an endoscopy clinic, and cleaned, but not disinfected, according to standard cleaning procedures of the clinic, were exposed for 5.0 minutes at 20°C to worst-case ACECIDE-C from a 5-day EPA Reuse Test, further diluted to 2000 ppm peracetic acid. No (zero) bacteria were recovered from these endoscopes after the exposure to ACECIDE-C.
Olympus bronchoscopes as received directly from patients at a hospital, and processed as above, were exposed for 7.0 minutes to ACECIDE-C at 20°C as above. No (zero) bacteria were recovered from these endoscopes after the exposure to ACECIDE-C.
#### k. Summary of ACECIDE Test Strips
ACECIDE Test Strips are used with ACECIDE-C use solution to ensure that the level of peracetic acid is above the minimum recommended concentration of 2000 ppm.
The test strips are based on the same basic chemistry as other peracetic acid test strips and assay methods. Peracetic acid oxidizes iodide to iodine with starch forming a visible blue-gray/blue-black compound with iodine. This color change in the indicator paper is the visual basis for the tests strips and their reading.
ACECIDE-C must be tested for peracetic acid concentration at the time of each use with ACECIDE Test Strips as manufactured by Merck KGaA (Darmstadt Germany).
- Summary of the conclusions drawn from the tests that indicate that ACECIDE-C l. High Level Disinfectant and Sterilant is as safe and as effective or better, than Acecide High Level Disinfectant and Sterilant.
We conclude that ACECIDE-C High-Level Disinfectant and Sterilant is as safe as Acecide High Level Disinfectant and Sterilant because the two products contain similar concentrations of peracetic acid throughout the use life, and are used at similar exposure temperatures. We conclude that ACECIDE-C is as antimicrobial or more antimicrobial than Acecide based on similar high level disinfection exposure times and temperatures, and that ACECIDE-C has a faster sterilization time at a lower temperature (2.0 hours at 20°C versus 5.0 hours at 25°C).
