Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
The substance shall be registered under Article 17 (on-site isolated intermediate); no testing is required; however, an indicative assessment of potential skin sensitizing properties based on non-testing methods is included in this IUCLID.
This indicative assessment of skin sensitizing properties is based on physico-chemical, toxicological, and in silico data. Experimental studies have not been performed for this endpoint.
The substance is of low acute oral toxicity in vivo and is only slightly irritating to rabbit’s skin. In occupational settings no skin effects as skin irritation or skin sensitization were reported. The substance showed no electrophilicity in two Ames tests in vitro.
There are some inconsistent and thus equivocal results for the substance with regard to potential skin sensitization profilers in silico. However, the physico-chemical properties of the substance (solid, very low solubility in water, log Pow >5) do not indicate a relevant dermal absorption potential. There is also no relevant skin irritation potential that would facilitate penetration through the stratum corneum.
In conclusion, the limited available information with special emphasis on the physico-chemical data in this indicative evaluation does not point to a relevant skin sensitization potential in vivo.

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.
