Link to relevant study records
Reference
Endpoint:
skin sensitisation: in vivo (non-LLNA)
Type of information:
other: read across from analogue substance
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The study has been presented to ECHA in the framework of a NONS notification. The document is now public because presented more than 12 years ago. The summary received is from migrated NONS dossier

Maximu concentration not causing irritating effects in preliminart test: 1%

Sign of irritation during induction: no skin reactions on the guinea pig skin were observed

Evidence of sensitisation of each challenge concentration: 7 of 20 animals in the test gropup and 2 of 20 animals in the negative control group

Interpretation of results:
other: not classified under Regulation 1272/2008
Remarks:
Migrated information
Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

The analogue substace was tested for sensitising properties following EU Methob B6. Under the experimental conditions (in vivo traditional sensitisation test with Guinea Pig) the substance did not elicit any sensitisation.

Based on the read across considerations the same applies to Direct Blue 299

Migrated from Short description of key information:

no sensitising

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available

Justification for classification or non-classification

The substance is not classified for skin sensitisation under Regulation 1272/2008.
