Endpoint:
adsorption / desorption: screening
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low octanol water partition coefficient and the adsorption potential of this substance is related to this parameter
Justification for type of information:
The n-octanol/water partition co-efficient (log Pow) of FAT 40000 at 20 °C was determined to be -5.70 (Pow = 1.99E-6).

Description of key information

This study is waived since the substance has low Partition coefficient value ( -5.70).

For the purpose of risk assessment calculated QSAR value using EPA tool a value of 0.425 is considered.

Key value for chemical safety assessment

Koc at 20 °C:
0.425

Additional information

Based on the low Partition coefficient value (< 3) the substance is expected to have a low potential for adsorption. Hence, the study can be waived.The n-octanol/water partition co-efficient (log Pow) of FAT 40000 at 20 °C was determined to be -5.70 (Pow = 1.99E-6).
