The Department of Agriculture, Food & the marines, along with the HSE have ask consumers to be vigilant of counterfeit hand sanitisers and disinfectants. These products may contain substances that are not from approved sources or substances that are not approved for use in biocidal products. Furthermore, these products may not be efficacious (not contain enough alcohol to kill/remove germs) and may make unsubstantiated claims which could put your health at risk. Similarly, using homemade recipes found online could put your health at risk.
