Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The registered substance is a complex UVCB whose constituents have variable physicochemical properties. Therefore, a modelling 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, modelled data are considered fit for purpose.
Detailed information covering the calculation model, compositional data used as input, validity, applicability and adequacy of the result are attached in section 13.2 of IUCLID.
Key value for chemical safety assessment
Additional information
The target lipid model (2015) and equilibrium partitioning model as described in the cited references were used to determine sediment effect levels following an estimation of initial loading of the registered substance and its constituents in the substrate. The Hydrocarbons, C11-C14, n-alkanes, isoalkanes, <2% aromatics estimated 28-day LC50 value is >1000 mg/L based on mortality and the EC10 value is >1000 mg/L based on reproduction/biomass for the sediment species Lumbriculus variegatus.
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.
