Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Toxicokinetic / pharmacokinetic studies

Details on absorption:
The substance and / or its degradation products are absorbed by oral route since systemic effects are noted after exposure by this route.
(Based on the base-set data)
Details on distribution in tissues:
Based on in-vitro data indicating that a slight difference in toxicity was noted in assays with and without metabolic activation system, the substance
MENAPHTACYAN could be metabolized by hepatic microsomal fractions. Centrilobular hepatocellular hypertrophy shows that the substance and/or its degradation products are probably metabolized by this organ. (corroboreted by in-vitro data)
Details on excretion:
In the absence of effects on kidneys, it is difficult to indicate if MENAPHTACYAN is excreted by this organ.
On the basis of the log P, MENAPHTACYAN could have a weak potential to bioaccumulate

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): low bioaccumulation potential based on study results
