Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Short-term aquatic toxicity data are available for three trophic levels (fish, invertebrates and algae). The acute effect values for fish (Leuciscus idus), daphnids (Daphnia magna) and algae (Desmodesmus subspicatus) are 14.66 mg/L, 22.53 mg/L and 13.61 mg/L, respectively. The substance does not need to be classified for acute aquatic hazard.
Long-term aquatic toxicity data are available only for aquatic algae for which an ErC10 of 4.16 mg/L was determined. Based on this chronic data and as the substance is readily biodegradable, 4-hydroxybutyl acrylate does not need to be classified for chronic hazard.
As the substance is readily biodegradable and has a log Pow of 0.77 (no experimental BCF available) chronic classification of 4-hydroxybutyl acrylate does not have to be based on acute data. Overall, the substance does not have to be classified in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008.
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.
