Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No toxicity studies have been carried out on terrestrial plants with registration substance. PETROTOX model v 4.01 predicted values are available.
The predicted 14-d EL50 (seedling emergence) of this substance to Avena sativa is 3,534 mg/kg soil dw and the predicted 21-d EL10 (growth) is 677 mg/kg soil dw.
The predicted 14-d EL50 (seedling emergence) of this substance to Brassica rapa is 2,282 mg/kg soil dw and the predicted 21-d EL10 (growth) is 437 mg/kg soil dw.
Key value for chemical safety assessment
Additional information
The registered substance is a complex petroleum UVCB whose constituents have variable physicochemical properties. Therefore, a modeling framework is needed to account for the bioavailability of the constituents in the mixture, which was then used to predict the toxicity of the substance as a whole. The target lipid model (TLM) and HC5, have been applied to soils and sediment using equilibrium partitioning (EqP) model. As such, modeled data are considered fit for purpose. The model used for the calculations was the PETROTOX v4.0 model. PETROTOX is a well-documented and peer reviewed model that is widely used across the chemicals industry.
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.
