Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Justification for selection of genetic toxicity endpoint
No study selected as there were no adverse effects to warrant selection of a particular study.

Short description of key information:
HCAT was not mutagenic in strains of S. typhimurium and E. coli when dissolved and diluted in ethanol and tested in the absence and presence of metabolic activation. HCAT was tested at concentrations that extended into the toxic range in the absence of metabolic activation and up to the predetermined maximum concentration of 5000 μg per plate in the presence of metabolic activation. This latter treatment was beyond the limit of HCAT’s solubility in the test system.

Cytogenicity and mammalian gene mutation from HCAT is not expected to occur due to the lack of any such effects expressed by the components of this organimetallic complex, molybdenum and 2-ethylhexanoic acid.

Endpoint Conclusion: No adverse effect observed (negative)

Justification for classification or non-classification

There was no basis for classification of HCAT for genetic toxicity.
