Maximum concentration not causing irritating effects in preliminary study: 50%

Signs of irritation during induction: yes

Evidence of sensitisation of each challenge concentration: none

No more information is available in the migrated NONS file provided by ECHA.

Interpretation of results:
not sensitising
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The test article has been determined not to be a dermal sensitiser.
Executive summary:

All information in this endpoint has been provided by the ECHA using the 12 year rule, this data is not owned by the registrant.

The test item appeared not to be a sensitiser when tested under OECD Guideline 406 (1981). As a consequence, the test material do not fullfill the classification criteria for skin sensitisation according to DSD (67/548/EEC) or CLP (1272/2008).

Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:
Migrated from Short description of key information:
two different studies OECD406 on guinea pig where performed with two different vehicle (absolute ethanol or arachis oil). The results indicated no sensitisation effect with the test substance.

Justification for selection of skin sensitisation endpoint:
report on test substance provided by ECHA using 12 year rule

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available

Justification for classification or non-classification

The test material was tested according to the OECD Guideline 406 on guine pigs in two studies. The substance do not fulfill the classification criteria for skin sensitisation according to DSD (67/548/EEC) or CLP (1272/2008).
