Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Data waiving according Regulation (EC) 1907/2006, article 1 and 3:
The substance is readily biodegradable. Furthermore, as the logKoc is below 3 and a low adsorption potential is indicated. Therefore, binding to sewage sludge is unlikely. For a substance being considered as „readily biodegradable“, it can be assumed that it will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected.
According to Annex I of this regulation, the chemical safety assessment triggers further action when the substance or the preparation meets the criteria for classification as dangerous according to Regulation (EC) 1272/2008 or is assessed to be a PBT or vPvB. The hazard assessment of Hydroxyethylpyrrolidon reveals neither a need to classify the substance as dangerous to the environment, nor is it a PBT or vPvB substance, nor are there any further indications that the substance may be hazardous to the environment.
Therefore, no tests on terrestrial organisms are provided. Thus, the PNEC derivation will be based on the equilibrium partitioning method (EPM).
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.
