Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Description of key information

One experimental study is available for the skin sensitisation endpoint for the test substance. This study is compliant under Annex V on EU method B.6 (skin sensitisation) guidelines.

According to the results of this study, the test substance did not meet the GHS criteria. Therefore, it should be considered as not sensitising for the skin.

Reference
Endpoint:
skin sensitisation: in vivo (non-LLNA)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Qualifier:
according to guideline
Guideline:
EU Method B.6 (Skin Sensitisation)
GLP compliance:
yes
Type of study:
Buehler test
Justification for non-LLNA method:
The skin sensitisation in-vivo (non-LLNA) experimental study reported in this section should be considered as acceptable since it was performed before the LLNA skin sensitisation method was considered to be the preferred one for new in-vivo testings.

Moreover and according to ECHA guidance R.7a, page 234, existing data of good quality derived from tests such as the Buehler test are acceptable and, if they provide clear results, will preclude the need for further in vivo testing.
