Biocidal active substances

INTERHYGIENE prepares dossiers for the authorization of biocidal active substances within the EU or contributes to them. The authorizations are very comprehensive and require exact exposure scenarios to keep the impact of substances on humans, animals and environment as low as possible. This is also valid for biological active substances.

Customers expect high efficacy from these substances e. g. against animal diseases. Tests according to European norms and field trials are mandatory to prove the efficacy. The goal is maximum efficacy at minimum exposure.

INTERHYGIENE submitted their own dossier for authorization of formaldehyde as a biocidal active substance for PT 3 (veterinary hygiene). INTERHYGIENE owns the rights to access the data of the dossier and is listed as supplier according to Article 95. Within the EU this is the prerequisite for using the active substance or for adding the substance to a biocidal product.
