Ensuring the Compatibility of Our Disinfectants Is a Top Priority

While no disinfectant can guarantee absolute compatibility with all materials, our rigorous in-house testing, strategic collaborations with medical device manufacturers, and stringent external testing at ISO 17025 accredited laboratories for final material compatibility evaluations-affirm that our disinfectants are exceptionally suited for a broad spectrum of surfaces, encompassing various metals, plastics, and polymers.
  • No visible surface damage or effect on the material is likely to occur when used according to label directions. No change to the integrity of the material is expected.
  • Some visible surface damage such as tarnishing or clouding may be seen with long-term exposure. Little to no effect on material intergrity is expected. Periodic wiping of surfaces with a clean damp cloth to remove residue can help to minimize damage.
  • Visible damage to the surface is likely to occur with long-term exposure and some effect on material integrity is possible. Surfaces should be wiped with a clean damp cloth immediately after the contact time has been reached to reduce the risk of damage. Users should evaluate the risk of surface damage vs the benefits of disinfectant efficacy against pathogens to determine whether the products is appropriate for use.

The Diversity of Materials in Healthcare – From Metals to Polymers – Makes Compatibility with Disinfectants and Cleaners Crucial

Recognizing and addressing material incompatibilities is of paramount significance in the medical industry. The utilization of disinfectants and cleaners that are not harmonious with specific materials can result in detrimental outcomes, including material degradation, corrosion, or impaired functionality in essential healthcare instruments. These incompatibilities can induce chemical reactions, hasten wear and tear, and ultimately curtail the useful lifespan of these critical tools. Furthermore, material degradation or corrosion can establish an optimal environment for pathogenic proliferation, thereby compromising the disinfection and cleaning processes designed to uphold the sterility of healthcare environments. Consequently, the effectiveness and durability of healthcare instruments are contingent not only on their manufacturing quality but also on the intricate interaction between the materials comprising them and the disinfectants and cleaners applied to preserve their structural integrity and

The Challenge of Degradation, Corrosion, or Loss of Functionality

The healthcare industry encounters substantial challenges when it comes to disinfecting and cleaning medical instruments, primarily due to the extensive array of materials employed in these tools. The paramount objective is to eradicate pathogens effectively while safeguarding the integrity and functionality of these instruments.

A significant hurdle in healthcare revolves around the potential harm that specific disinfectants and cleaners can cause to diverse instrument materials. The chemical interactions between disinfectants, cleaners, and instrument materials can result in corrosion, structural harm, or diminished performance. For instance, chlorine-based disinfectants and cleaners can erode metals like stainless steel, alcohol-based solutions may render plastics and rubber fragile, and quaternary ammonium compounds (Quats) can leave residues that adversely impact instrument performance.

The resolution for addressing the degradation, corrosion, and functional loss of healthcare instruments hinges on a collaborative approach. Instrument manufacturers must prioritize the use of durable and resilient materials. Simultaneously, disinfectant and cleaner manufacturers should emphasize the formulation of disinfectants and cleaners that are gentle on these materials while maintaining their efficacy.

At Oro Clean Chemie AG, we wholeheartedly embrace this approach as part of our unwavering commitment to excellence in healthcare disinfection. We ensure that our disinfectants and cleaners are not only potent in eliminating pathogens but also compatible with a wide range of healthcare instrument materials. This ensures that healthcare professionals never find themselves in the challenging position of choosing between clinical effectiveness and the longevity of their vital healthcare instruments.


  • How is the exposure time determined for disinfectants?
    European standards specify the required exposure times for disinfectants to achieve their claimed efficacy. The standards provide detailed instructions on the duration of contact between the disinfectant and the microorganism to ensure effective inactivation or reduction.
  • What's the main goal of the EN 14885:2022 document, especially in a medical context?
    EN 14885:2022 serves as a comprehensive guide for chemical disinfectants and antiseptics, especially in the medical field. It outlines the standards for testing these products to ensure they are effective and safe for use in various medical settings, like hospitals and clinics. The document helps manufacturers validate their product claims, assists users in selecting appropriate products, and guides regulatory authorities in evaluating these products.
  • Can you explain the difference between 'with mechanical action' and 'without mechanical action' in EN 14885:2022?
    With mechanical action" refers to the process of physically wiping a surface or object with a disinfectant, enhancing the removal of microbes. This is common in settings where thorough cleaning is necessary. "Without mechanical action" means applying the disinfectant without any physical aid, for example through spraying. This method relies solely on the chemical properties of the disinfectant to kill or deactivate microbes. The choice between these methods depends on the specific requirements of the healthcare setting and the type of surface being disinfected.
  • How do I determine if a disinfectant is safe for use on dental equipment with various material components?
    To ensure the safety of dental equipment, you should reference the equipment manufacturer's instructions for care and the disinfectant's material compatibility list. Some dental equipment materials, like certain plastics or silicone, may require specific types of disinfectants to prevent damage.
  • Are there any best practices for testing the compatibility of a new disinfectant with healthcare materials?
    Best practices for testing a new disinfectant include conducting spot tests on a small, inconspicuous area of the material, monitoring for any adverse reactions, and verifying the results against the disinfectant's material compatibility chart. It's also recommended to consult with the disinfectant manufacturer for any specific testing protocols or guidelines they may provide.
  • What is EN ISO 21530 and how does it relate to the use of disinfectants in healthcare?
    EN ISO 21530 is a standard that specifies the requirements and test methods for assessing the compatibility of disinfectants with the materials used in medical devices. Its main objective is to ensure that the physical and chemical properties of medical device materials are maintained even after repeated disinfection processes. This ensures that the products can continue to be used safely and effectively in the healthcare sector.
  • How does EN ISO 21530 influence the selection of disinfectants for medical devices?
    EN ISO 21530 has a significant impact on the selection of medical device disinfectants by providing healthcare providers with clear information on which disinfectants have been thoroughly tested and proven to have no harmful effects on the materials used in their medical devices. This enables professionals to select disinfectants that will not compromise the integrity or functionality of the devices and therefore maintain the highest safety standards.
  • When should I use an ultrasonic device for cleaning and disinfection?
    An ultrasonic device is especially suitable to clean and disinfect heavily contaminated instruments, or to remove stubborn residues such as cement or plaster that persist after disinfection. Following such cleaning, however, the instruments must be disinfected again. Devices with many sensitive parts, such as handpieces, generally cannot be cleaned in an ultrasonic device.
  • Why must instruments be disinfected before sterilization?
    Medical instruments are often sharp and thus pose an increased risk of injury. For this reason, it is important that healthcare professionals always treat used instruments as potentially infectious. The reprocessing cycle should therefore begin with disinfection to protect the staff responsible for further reprocessing steps such as cleaning, inspection, instrument care, sterilization, and packaging. The use of a disinfectant with high cleaning power, such as OROLIN® Multisept Plus, can help reduce or even eliminate the need for manual cleaning.
