Nicolas Gallacier: R&D in biocides is heavily influenced by regulatory pressure in Europe. Gallacier: The reduced number of approved active substances and lower concentration limits are raising concerns about the overall effectiveness of preservation systems. Addressing this requires a holistic approach: What preservation systems are used by the emulsion suppliers? Especially in water-based industrial products, robust and sustainable preservation systems are essential. Only biocidal solutions that are evaluated and approved under the BPR offer proven efficacy against target organisms while ensuring safety for human health and the environment.
