Description of key information

Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

SYN545192 was negative for skin sensitisation potential in the mouse local lymph node assay. 


Migrated from Short description of key information:
SYN545192 is not a skin sensitiser nor is it considered to have potential to cause respiratory sensitisation

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

SYN545192 is considered not to be a respiratory sensitiser based on its lack of skin sensitisation potential and also the lack of any structural alerts for respiratory and skin sensitisation potential (DEREKTM: Version 2.0.2.201111291322; February 2012)


Migrated from Short description of key information:
SYN545192 is judged not to be a respiratory sensitiser

Justification for classification or non-classification

Based on the available information the substance does not meet the criteria for classification as "skin sensitiser" under Regulation (EC) 1272/2008, Annex I, Part 3, 3.4.2.2; reason for non-classification: conclusive but not sufficient for classification.

Based on the available information the substance does not meet the criteria for classification as "respiratory sensitiser" under Regulation (EC) 1272/2008, Annex I, Part 3, 3.4.2.1; reason for non-classification: inconclusive.
