ECHA recommends thirteen Substances of Very High Concern for authorisation

On 21 December 2011, the European Chemicals Agency has submitted to the European Commission a recommendation that thirteen Substances of Very High Concern should in future not be used without authorisation. These substances are all classified because of their carcinogenic, mutagenic or toxic to reproduction (or a combination thereof) properties.

The thirteen substances and their main uses within the scope of authorisation are:

1. Trichloroethylene (carcinogen). A substance mainly used in surface cleaning, in textile scouring, in adhesives and as a heat transfer fluid.

2. Chromium trioxide (carcinogen, mutagen). A substance mainly used for metal finishing and as a catalyst.

3. Acids generated from chromium trioxide and their oligomers (group containing: chromic acid, dichromic acid, oligomers of chromic acid and dichromic acid) (carcinogen). A substance that could be used to replace chromium trioxide in many of its uses.

4. Sodium dichromate (carcinogen, mutagen, toxic for reproduction). A substance mainly used in metal surface treatment.

5. Potassium dichromate (carcinogen, mutagen, toxic for reproduction). A substance mainly used in metal surface treatment and as a processing aid.

6. Ammonium dichromate (carcinogen, mutagen, toxic for reproduction). A substance with currently no uses in the scope of authorisation. It could however be used to replace other chromium(VI) substances.

7. Potassium chromate (carcinogen, mutagen). A substance mainly used in metal surface treatment.

8. Sodium chromate (carcinogen, mutagen, toxic for reproduction). A substance mainly used in metal surface treatment.

9. Cobalt(II) sulphate (carcinogen, toxic for reproduction). A substance mainly used in surface treatment processes and as a water treatment chemical, oxygen scavenger and corrosion inhibitor.

10. Cobalt dichloride (carcinogen, toxic for reproduction). A substance mainly used in surface treatment processes and as a water treatment chemical, oxygen scavenger and corrosion inhibitor.

11. Cobalt(II) dinitrate (carcinogen, toxic for reproduction). A substance mainly used in surface treatment processes and as a water treatment chemical, oxygen scavenger and corrosion inhibitor.

12. Cobalt(II) carbonate (carcinogen, toxic for reproduction). A substance mainly used in fertilisers and in surface treatment processes.

13. Cobalt(II) diacetate (carcinogen, toxic for reproduction). A substance mainly used as a catalyst and in surface treatment processes.
