Dutch Firm Appeals Against Echa Decision on Disodium Molybdate

Chemicals producer, Climax Molybdenum, has asked Echa's Board of Appeal (BoA) to annul an agency ruling that requested further data on the substance disodium molybdate under a REACH compliance check.

The Dutch company was asked to submit a prenatal developmental toxicity study by 20 March 2018.

Its registration dossier already contains such a study but Echa claims that it does not meet OECD testing guidelines.

Climax Molybendum disagrees and wants the existing study to be be accepted as valid in its dossier, as per the OECD mutual acceptance of data (MAD) scheme. The agency was wrong to say it does not meet OECD guideline specifications, the company says.

And it erred in requesting a higher dose for the new test, which would cause excessive toxicity and sacrifice too many animals, it claims.

Disodium molybdate is commonly used in anti-freeze products, heat transfer fluids, fertilisers and water treatment chemicals.
