Reference
Endpoint:
partition coefficient
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
The substance EDTA-NiNa consists of the inorganic salt nickel and sodium and the organic moiety Ethylenediaminetetraacetic acid. For the first the partition coefficient does not has to be determined. For the latter the determination is performed by EPI Suite, KOWWIN v1.68 which is an accepted programm for the calculation of this endpoint.
Qualifier:
no guideline required
Principles of method if other than guideline:
The determination is performed by EPI Suite, KOWWIN v1.68 which is an accepted programm for the calculation of this endpoint.
Key result
