Disinfectant testing is used to validate the microbicidal activity of disinfectant products against surface-adhered microorganisms. On the basis of the intended use of disinfectants, test microorganisms and other laboratory conditions are selected for their efficacy testing.

Why Disinfectant Efficacy Testing is Important?

Disinfectants are the primary mode of routine cleaning and hygiene practices in houses, health care settings, workplaces, and other common public areas. The biocidal action of disinfectants helps in eliminating the pathogenic microbes (bacteria, viruses, fungi, etc) present on inanimate objects, hence reducing the exposure to infections. Surface disinfection plays a crucial role to prevent cross-infection that happens due to the contact with contaminated surfaces.

Before launching a disinfectant product to the market or using it in real conditions, it is pertinent to evaluate the manufacturer’s efficacy recommendations. The efficacy of disinfectant products is measured by their “log reduction” value. Log reduction is a mathematical term used to define the relative number of living microorganisms that disinfectant eliminates in a given amount of time. And to make the performance claims, a disinfectant product needs to achieve a 5-log reduction value against the test microorganisms, which means that the sample inactivates (kills) 99.999 % of microbes.

Disinfectant and Sanitizer Test Methods

At Microbe Investigations, we perform following efficacy test for surface disinfectants and antiseptic formulations –

  • EN 1276Test for the evaluation of the bactericidal activity of chemical disinfectants 
  • EN 14476 Test for the evaluation of the virucidal activity of chemical disinfectants 
  • EN 13697 –  Nonporous surface test for the evaluation of bactericidal activity of disinfectants

Examples of the Disinfectant Products Tested at MIS

We assess the efficacy of chemical disinfectant and antiseptic formulations used in food, industrial, domestic, and institutional areas.

Here, the major product samples that we receive for testing include

  • Hand Sanitizers
  • Handwash
  • Liquid disinfectants
  • Gels
  • Textile hygienizers
  • Automobile hygienizers
