Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

In a 'read across' acute daphnia study with diesel fuel the 48hr EL50 was determined to be 210 mg/L based on immobilisation.

Supporting PETROTOX (version 4.01) modelled values are available. The aquatic toxicity was estimated using the PETROTOX computer model, which combines a partitioning model (used to calculate the aqueous concentration of hydrocarbon components as a function of substance loading) with the Target Lipid Model (used to calculate acute and chronic toxicity of non-polar narcotic chemicals). PETROTOX computes toxicity based on the summation of the aqueous-phase concentrations of hydrocarbon block(s) that represent a petroleum substance and membrane-water partition coefficients (KMW) that describe the partitioning of the hydrocarbons between the water and organism. 

The model predicted LL50 of the substance to aquatic invertebrates to be > 1,000 mg/L.

QSAR predictions on short term toxicity to aquatic invertebrates of EC 941 -364 -9 have also been provided to support the read-across.
