Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Formula for the calculation of PNECsed using the equilibrium partitioning approach for sediment:
PNEC(sed) = (Ksed-water x PNEC(aqua) / RHOsed) * 1000
PNEC(sed) Predicted No Effect Concentration in sediment [mg/kg, wet weight]
Ksusp-water partition coefficient sediment / water [1.67 m3/m3]
RHOsed bulk density of sediment matter [1150 kg/m3]
PNECaqua Predicted No Effect Concentration in water [as above]
Formula for the calculation of PNECsed using the equilibrium partitioning approach for soil:
PNEC(soil) = (Ksoil-water x PNEC(aqua) / RHOsoil) * 1000
PNEC(soil) Predicted No Effect Concentration in sediment [mg/kg, wet weight]
Ksoil-water partition coefficient sediment / water [2.05 m3/m3]
RHOsoil bulk density of soil matter [1700 kg/m3]
PNECaqua Predicted No Effect Concentration in water [as above]
Conclusion on classification
The toxicity of 2 -butoxyethyl acetate falls within the range for potential classification as harmful to aquatic species. However, the fact that it is readily biodegradable means that it does not meet the criteria for classification.
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.
