Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Above demonstrated computations on the different PNECs all are based on the standard default factors given by ECHA's "Guidance on information requirements and chemical safety assessment Chapter R.10: Characterisation of dose [concentration]-response for environment" and "ECB - Technical Guidance on Risk Assessment, in support of Commission Directive 93/67/EEC on Risk Assessment for new notified substances, Commission Regulation (EC) No 1488/94 on Risk Assessment for existing substances, Directive 98/8/EC of the European Parliament and of the Council concerning the placing of biocidal products on the market, Part II".
Conclusion on classification
The most sensitive acute aquatic toxicity study was the study with algae, revealing an EC50 of 11 mg/L. In combination with the fact that substance registered is not readily biodegradable; the resulting CLP classification is “Hazardous to the aquatic environment (long-term) – Aquatic Chronic 3 and with Hazard statement H412: Harmful to aquatic life with long lasting effects”. The corresponding DSD classification is “R52/53 Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment”.
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.
