Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- partition coefficient
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance decomposes

Description of key information
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the substance is hydrolytically unstable.
The partition coefficient of the primary amine transformation product has been presented in a separate endpoint summary for use in the CSA.
Key value for chemical safety assessment
Additional information
With reference to Section 5.1.2 endpoint summary, isocyanates (i.e. m-toly isocyanate) are rapidly hydrolysed (DT50 <1h) under environmentally relevant conditions. Therefore, it is appropriate to conduct experimental testing (in the aqueous compartment) on the primary amine transformation product, in this instance, m-toluidine.
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.
