KUALA LUMPUR, Sept 21 (Bernama) -- Ministry of Heath Malaysia is concerned regarding the issue raised on safety and effectiveness of nano mist spray as a disinfecting device.

Nano mist spray delivers nano size particles which is widely used for various purposes including cosmetics, perfume, domestic and industrial use. It is available in many forms and sizes, ranging from spray gun and handheld spray for personal use and larger size for industrial use.

Lately, this product has gained public attention in its use as a disinfecting tool to prevent transmission of COVID-19. Some members of the public believe this device can kill SARS-CoV-2 virus in air and surface. However, the effectiveness of this device is dependent on its dispersion ability, the disinfectant type used and its concentration, as well as the contact time between disinfectant and surface.

In general, currently several surface disinfectants have been identified to be effective against SARS-CoV-2 such as alcohol 70%-90%, hydrogen peroxide, thymol, quaternary              ammonia,     and             chlorine-based            solution.   The   list   of recommended surface disinfectant against SARS-CoV-2 is available from the US                       Environmental                   Protection              Agency              website https://www.epa.gov/coronavirus/about-list-n-disinfectants-coronavirus-covid- 19-0, which is an international reference for disinfectant.

Ministry of Health Malaysia would like to emphasise that the disinfecting solution as mentioned above is for the purpose of surface disinfection and not meant to be used directly on human. This is due to the fact that, contact with some of this solution may cause irritation to the eyes, skin, respiratory and gastrointestinal system.

It is also important to highlight that the use of nano mist does not replace the requirement for standard surface cleaning.

Guidelines on Surface Disinfectant Registration by Ministry of Health is available for                                public              viewing                                       from https://www.npra.gov.my/images/Guidelines_Central/surface_disinfectant/Revi sion_1_Guideline_for_Registration_of_Surface_Disinfectant.pdf        .        This guideline also describes disinfectant labelling requirements. Other than that, assessment reports on various disinfection methods can be accessed from https://covid-19.moh.gov.my/kajian-dan-penyelidikan/mahtas-covid-19-rapid- evidence-updates.

Thank you.
