Description of key information

Key value for chemical safety assessment

Skin sensitisation

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

One study is available for this endpoint and was considered as the key study (Kr: 1).

No effects were highlighted during a guinea pig maximilization test with the substance, comparable to OECD 406 guideline. The substance is therefore not classified for this endpoint.


Justification for selection of skin sensitisation endpoint:
One study available.

Respiratory sensitisation

Endpoint conclusion
Additional information:
Migrated from Short description of key information:
No data was available

Justification for classification or non-classification

Skin sensitisation:

Intradermal induction was performed with a test concentration of 5% followed by a 48-hour occlusive patch with 100% DP 1268 seven days later. After a 14-day interval, challenge was performed by application of an occlusive chamber with 100% DP 1268 to a prepared flank for 24 hrs.

No sensitzing activity of DP 1268 was indicated in the guinea pig maximization test.

Respiratory sensitisation:

Classification not possible due to lack of data.
