Type of information:
Adequacy of study:
key study
Study period:
2017 April 04
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Estimated data are obtained from a reliable (Q)SAR program developed and validated by the United States Environmental Protection Agency (U.S. EPA). The program is included in the OECD (Q)SAR Toolbox for use in filling REACH data gaps.
no guideline followed
Principles of method if other than guideline:
Validated (Q)SAR estimate (U.S. EPA MPBPVP v1.43)
GLP compliance:
Type of method:
other: Calculation method
