Impact of artificial accelerated ageing of PVC surfaces and surface degradation on disinfectant efficacy
Summary
Researchers examined how artificial aging and surface degradation of PVC surfaces affects the efficacy of disinfectants, finding that surface type and age can alter biocide performance in unpredictable ways, highlighting a gap in current standardized efficacy testing protocols that typically use pristine surfaces.
We showed that surface type and surface ageing can affect biocidal product efficacy, although in a non-predictable manner. More research is needed in this field to ascertain whether surface types and aged surfaces should be used in standardized efficacy testing.
