Endpoint:
partition coefficient
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is inorganic
Endpoint:
partition coefficient
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is inorganic
the study does not need to be conducted because the substance does not dissolve in water or in octanol
other:
Justification for type of information:
Transformation dissolution test demonstrates that substance is slightly soluble. When dissolved, the substance dissociates in water in Ag and behenate to levels above the ecotoxicity reference value. In accordance with column 2, Annex VII of the regulation (EC) 1907/2006 (REACH), the partition coefficient study does not need to be conducted as the substance if the test cannot be performed: the substance decomposes partly in Ag and behenate acid.
For Ag, in accordance with column 2, Annex VII of the regulation (EC) 1907/2006 (REACH), the partition coefficient study does not need to be conducted as the substance is inorganic.
Read-across to behenate is done.

Description of key information

Transformation dissolution test demonstrates that substance dissociates in water in Ag and behenate to levels above the ecotoxicity reference value.

In accordance with column 2, Annex VII of the regulation (EC) 1907/2006 (REACH), the partition coefficient study does not need to be conducted if the test cannot be performed: as the substance decomposes partly in Ag and behenate acid.

For Ag, in accordance with column 2, Annex VII of the regulation (EC) 1907/2006 (REACH), the partition coefficient study does not need to be conducted as the substance is inorganic. For behenate, the log Pow was calculated at 9.91.
