In May 2020, the VAH (Association for Applied Hygiene e.V.) increased the requirements with regard to the stability for the approval of products based on chlorine-releasing compounds. Hydroliq has commissioned 2 new proofs of effectiveness from 2 independent, accredited laboratories and passed them with flying colors. This now results in the official VAH certification, which is necessary for the use of the disinfection solutions in health facilities/hospitals in Europe.
