Testing Biocides

Efficacy studies on biocides: for chemical disinfectants and antiseptics and airborne disinfection devices.

Are you developing a disinfectant or an airborne disinfection device?

Abich – Lifeanalytics laboratories help you make sure that your product has an adequate disinfectant efficacy according to current regulations: UNI EN 14885:2019 and related regulations, UNI EN 17272:2020, and many more.

The biocidal products industry for medical but also veterinary, industrial, food, domestic and institutional use has evolved a lot as regards formulations and technologies, and the demand for biocidal products has increased significantly in all areas.

These products belong to different product categories: hand gel (or hand rub), hand soap (or hand wash), disinfectants for instruments, disinfectants for surfaces and fabrics, surgical disinfectants and airborne disinfectants.

In order to substantiate the efficacy claims of antiseptic chemical disinfectants and automatic devices with gas, steam or aerosol dispenser, all the products must be tested according to relevant regulations:

  • UNI EN 14885:2019 is the regulatory reference defining the guidelines and the technical standards to adopt during the different phases of study for chemical disinfectants and antiseptics,
  • UNI EN 17272:2020 is one of the key methods for automated devices for airborne room disinfection with gas, steam or aerosol dispenser. It allows to qualify both the dispensing device and the product as effective on non-porous surfaces.
