Description of key information

Key value for chemical safety assessment

Repeated dose toxicity: via oral route - systemic effects

Link to relevant study records
sub-chronic toxicity: oral
Type of information:
experimental study planned
Study period:
Study will be conducted upon approval of ECHA.
Justification for type of information:
Hazard endpoint for which vertebrate testing was proposed:
Repeat dose toxicity.

Considerations that the general adaptation possibilities of Annex XI of the REACH Regulation were not adequate to generate the necessary information:

available GLP studies
No available GLP studies on the substances for the endpoint ‘repeat dose toxicity’.

available non-GLP studies
No reliable non-GLP studies are avaialable for the endpoint ‘ repeat dose toxicity’.

historical human data
No human data suggesting repeat dose toxicity are available for this substance.

No validated (Q)SAR’s exist for this endpoint for this substance

in vitro methods
In accordance with ECHA’s guidance on the information requirements and chemical safety assessment, chapter R7a. With regards to in vitro studies for repeat dose toxicity, the regulatory acceptance of these studies and approaches to replace the animal testing for repeat dose toxicity has not been achieved as
they do not provide equivalent information and thus, cannot be used alone for classification and labelling and/or risk assessment.

weight of evidence
No available studies on the substances for the endpoint ‘repeat dose toxicity’.

No further data exists on analogous substances.

substance-tailored exposure driven testing [if applicable]
Based on existng exposure senario information thiis substance does not qualify for this exemption.

[approaches in addition to above [if applicable]
Not applicable

other reasons [if applicable]
Not applicable

Considerations that the specific adaptation possibilities of Annexes VI to X (and column 2 thereof) were not applicable:
Adaptation options as defined in Annexes VI to X were not applicable for this substance and this endpoint.
according to
OECD Guideline 408 (Repeated Dose 90-Day Oral Toxicity in Rodents)
Endpoint conclusion
Endpoint conclusion:
no study available (further information necessary)

Additional information

Justification for selection of repeated dose toxicity via oral route - systemic effects endpoint:
An O.E.C.D. test guideline no. 408 90-Day Subchronic study in the rat by the oral gavage route of exposure is proposed.

Justification for classification or non-classification
