Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
The substance is not classified in the Annex I of Directive 67/548/EEC. According to the information summarised below, no classification for the environment is needed:
- No acute effects have been found in the studies for the three trophic levels fish, daphnia and algae.
- Concerning long-term toxicity, no effects were observed to algae with a 72h-NOEC of >100 mg/l, based on nominal concentrations.
- The substance is not readily biodegradable.
- The substance has a low potential for bioaccumulation. Rapid hydrolysis of the substance (and isocyanates in general) makes approximation of equilibrium in the environment impossible resulting in a low potential for bioaccumulation.
With the data listed above, the substance should not be classified according to DSD (Directive 67/548/EEC) and GHS (Regulation EC 1272/2008 including Commission Regulation EU-286/2011).
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.
