MARINE BIOCIDES MARKET
The marine biocide companies provide the marine paint industry with the necessary biocides to be incorporated into the paint formulations.
As of 2011, the dominating marine biocide companies are Lanxess, BASF/Ciba, Dow Chemicals/Rohm & Haas, Lonza/Arch Chemicals and Janssen PMP together with the collected copper industry.
The ban of TBT-based marine paints, as well as the recent, albeit limited, restrictions of copper compounds, has prompted extensive research and development activities to find new, sustainable technologies and substances. Several different strategies have been employed in the search for the optimal solution; biological deterrents and biocides, pharmaceutical biocides, and biocide free paint based on continuous release of paint layers, among others. At current, no single biocide or paint formulation has been able to satisfactory solve all aspects associated with the biofouling problem.
European Biocide Product Regulation
In 1998, the European Union introduced the Biocidal Product Directive (BPD) in an effort to regulate the biocide market, thus controlling the use of harmful substances. Marine antifoulants became subject to the directive within Product Type 21. The notification period ended in April 2006, during which a full dossier was to be presented to a competent authority for any biocidal substances currently on the European market. 10 out of the previous 47 registered marine biocides were notified. None of the notified organic substances address hard fouling.
I-Tech submitted its BPD dossier in April 2009 with the British chemical authority HSE for the registration of Selektope as an marine antifouling biocide.
On the 1st September 2013 the BPD was be revoked and replaced by the directly acting Biocide Product Regulation (BPR). The Selektope dossier is currently under evaluation as a new active substance according to the new regulation.
