Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
Substance specific information for the UVCB substance Doré is not available for the endpoint "Sensitisation". In order to meet the requirements for Annex VII till Annex X of Regulation (EC) 1907/2006, read across information from any constituents being relevant needs to be included. Due to the high number of constituents and variability in C&L of these constituents it was decided to use the classification information from the individual constituents and to calculate the resulting classification by using the generic concentration limits of ingredients of the mixture classified as skin sensitiser toxicant that trigger classification of the mixture and respective rules of Regulation (EC) 1272/2006 section 3.4.3.3 “Classification of mixtures when data are available for all components or only for some components of the mixture” with the MeClas tool.
This approach has been presented and discussed with ECHA in several meetings.
In total five different Doré grades (Doré 1 – Doré 5) were identified by the consortium that could be grouped according to their calculated C&L resulting from the individual composition. Thus, for Doré two C&L entries (i.e., no C&L and Skin Sens. 1) for skin sensitisation were calculated. Each group is described in a separate endpoint study record and endpoint summary.
Migrated from Short description of key information:
No information on animal testing of Doré is available. Since, Doré composition profile 4 till composition profile 5 (Doré 4 - Doré 5) contains constituent ≥ 1 % (i.e., nickel) that is itself classified for skin sensitisation; the substance must be classified as being a skin sensitiser, Skin Sens. 1 (H317). It is noted that no sub-categorisation was performed. For information on C&L for Doré - composition profile 1 till composition profile 3 (Doré 1 - Doré 3) please refer to the IUCLID endpoint summary "sensitisation - Doré 1 - Doré 3.
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
- Migrated from Short description of key information:
No information on animal testing of Doré is available. Since, Doré does not contain any constituent ≥ 0.1 % (w/w) that is itself classified for respiratory sensitization, the substance must not be classified as respiratory sensitiser.
Justification for classification or non-classification
Skin sensitisation
Doré 4 – Doré 5 possesses a skin sensitisation potential in accordance with Regulation (EC) 1272/2008. Hence, Doré 4 – Doré 5 does require classification as skin sensitiser in accordance with Regulation (EC) 1272/2008 Cat. 1 (H317).
Respiratory sensitisation
Furthermore, Doré does not contain any constituent ≥ 0.1 % (w/w) that is itself classified for respiratory sensitisation. Hence, the substance must not be classified as respiratory sensitiser in accordance with Regulation (EC) 1272/2008.
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).
