Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicokinetic / pharmacokinetic studies

Details on absorption:
Oral : possibly a minor systemic absorption of toxicologically active components based on a few systemic effects in oral studies and the molecular weight
Dermal : at least some sensitizing components are able to cross outer skin layers. Components with high molecular weight are expected not to cross the skin
Inhalation : no data, but expected fugacity is very low so that this route of exposure is negligible
Details on distribution in tissues:
The few toxicological effects did not evidence relevant target organs. Very limited distribution expected for components with high molecular weight
Details on excretion:
Expected minor excretion, in feces, of absorbed unchanged substance. Unabsorbed fraction excreted in feces after ingestion

Metabolite characterisation studies

Metabolites identified:
not measured

Any other information on results incl. tables

Metabolism : Clear in vitro ability of liver enzymes to detoxify, decrease genotoxic activity and increase solubility in hydrophilic vehicles. Biological relevance of this observation is negligible for dermal or inhalative exposures (limited absorption and absence of first-pass effect) and low to moderate for oral exposure (limited absorption but first-pass effect)

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): no bioaccumulation potential based on study results
No indication of possible bioaccumulation of toxicologically relevant components. Risk of bioaccumulation limited for components with high molecular weight
