Residual Activity Tests

Recently, there has been growing interest in obtaining residual efficacy claims (i.e., claims that a product has a continuous effect against microorganisms or viruses beyond the initial time of application). Traditional efficacy surface tests aim to demonstrate the disinfectants efficacy at a specific contact time. Stakeholders and the public are interested in products that prove active and effective beyond the moment of application.

Eurofins BioPharma Product Testing in Italy can give support for this specific claim, performing Residual Efficacy testing to demonstrate the effectiveness of biocidal disinfectant products both with immediate and prolonged effect against a wide variety of viruses.

Test methods are quantitative surface tests for the evaluation of residual virucidal efficacy of liquid chemical disinfectants on different types of surfaces.

Tailor-made protocols on viruses are based on US EPA Residual Sanitizing efficacy test protocol of dried chemical residues on hard and non-porous on hard and Non-Porous Surfaces (EPA 01-1A) and UK Residual Αntimicrobial efficacy test on hard non-porous surfaces (BS PAS 2424-2014)

We are committed to assist disinfectant manufacturers in achieving high-demand product claims for their disinfectants. Our team customizes and design suitable test methods that suits manufacturer needs, product application, and antimicrobial claim of interest. Disinfectant manufacturers may submit our test protocols to the regulatory authorities for approval prior to proceeding with testing. Contact us   if you would like us to get started on designing your customized test protocol.
