Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
Adequacy of study:
key study
Study period:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
no guideline available
Principles of method if other than guideline:
Estimated data are obtained from a reliable (Q)SAR program developed and validated by the United States Environmental Protection Agency (U.S. EPA). This program is included in the OECD (Q)SAR Toolbox for use in filling REACH data gaps
GLP compliance:
not specified
Type of method:
other: not specified
Specific details on test material used for the study:
SMILES: 0=C (OCCCCCC)c(ccc(c1C(c=C)OCCCCCC)C(=C)OCCCCCC)c1 no test material used.
