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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Additional information:
Because of the different results for skin sensitisatin (no skin sentisation vs skin sensitisation) with equal validity (but need for application depending on the substance purity):
- no endpoint conclusion is mentioned above
- as only one study can be indicated as key study, both studies were equally indicated as weight of evidence
Justification for selection of skin sensitisation endpoint:
One study reveals no skin sensitisation and the other reveals skin sensitisation for a subtance with the same ECnumber. After an analytical sameness check (see §1.4 of this dossier), the conclusion is that the most pure tested substance corresponds to the no skin sensitising result, thus not classified for this endpoint, while the less pure tested substance corresponds to the skin sensitising result, thus classified as H317 for this endpoint. As Agfa's substance is less pure, although we do not know the toxicity of our impurities, we include the worse classification and thus will include H317.
No additional value (= same result + no higher reliability possible) of non-shared data from FEW.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
