Key value for chemical safety assessment

Skin sensitisation

Endpoint conclusion
Endpoint conclusion:
adverse effect observed (sensitising)
Additional information:
Migrated from Short description of key information:
Determination of acute inhalation toxicity was carried out with 5-ethyl-2-methylpyridine (MEP, CAS no.: 104-90-5, EC no.: 203-250-0). The read-across between the UVCB substance and the model constituent is justified.
A study according to EU Method B.42, OECD Guideline 429 and EPA OPPTS 870.2600 (Skin Sensitisation: Local Lymph Node Assay) was carried out. Tested at concentrations of 50 %, 37.5 %, 25 %, 10 % and 5 % as homogenous formulations (solutions) in a suitable vehicle (AOO) the test item was shown to shown to have sensitization potential (sensitizer). The calculated EC3-value in this LLNA was 22.4 % based on linear interpolation and 18.1 % based on regression curve analysis. Based on the EC3 values calculated using dose-response and regression curve analysis the test item was considered a weak sensitizer.

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available
Additional information:
Migrated from Short description of key information:
There is no data available on respiratory sensitisation. However, there is no indication for respiratory irritation from handling and use.

Justification for classification or non-classification

Based on the data available the substance is classified and labeled according to Regulation 1272/2008/EEC (CLP) as Skin sensitiser category 1, H317 May cause an allergic skin reaction and according to Directive 67/548/EEC (DSD) as Irritant Xi, R43 May cause sensitisation by skin contact.
