Mastering the regulatory principles of ozone generated in situ from oxygen

30 minutes

Biocidal active substances are called in situ generated active substances if they are generated from one or more precursors at the place of use. The approval of these substances requires evaluation of the generated active substance and of the precursor(s) it is generated from, in the context of each product type (PT).



đź’ˇFor several years, ECHA has approved certain in situ generated substances as Active chlorine generated from sodium chloride by electrolysis from 01/07/2021.

In this line, ozone generated in situ from oxygen is on the ECHA's agenda, with an expected approval date of late 2024 or early 2025. Indeed, the Biocidal Products Committee (BPC)  has given a favorable opinion to the 2 active substance dossiers submitted by 2 different consortia and evaluated separately by Germany and the Netherlands.

As the approval date for ozone generated in situ from oxygen approaches, the transitional measures for marketing in situ generation systems (IGS) in Europe are in force. In addition, an authorisation dossier must be drawn up in order to continue selling them after the approval date.

✅ EcoMundo aims to offer transparent biocidal dossiers that are adapted to the customers’ needs.

In this webinar, a regulatory overview of the in situ generated active substance, the regulatory requirements for transitional measures and authorisation dossiers as well as possible strategies for ozone will be presented.

  • Understanding the Biocidal Products Regulation (BPR) with the different regulatory deadlines
  • Presentation of the different regulatory strategies
  • Technical pitfalls to avoid
