Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Materials and methods

Principles of method if other than guideline:
The biological basis for the model centers on the concept that within a chemical class, the
octanol/water partition coefficient (Kow) correlates with lipophilicity and the extent of uptake of
the material into the organism, and therefore, is a strong predictor of toxicity. ECOSAR
identifies chemical classes using the non-stereospecific SMILES coding of the molecule. For
each chemical class that may be identified, a predicted toxicity value may be generated by the
program, if a QSAR for that species and endpoint is available. ECOSAR reports the chemical
domain, based on log Kow, that is applicable to each QSAR.
