Administrative data

Endpoint:
surface tension
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
the study does not need to be conducted because surface activity is not a desired property of the material
the study does not need to be conducted because water solubility is below 1 mg/L at 20°C
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING.
In accordance with column 2 of REACh Annex VII, the study does NOT needs to be conducted if the water solubility is less than 1 mg/L. Please refer to Section 4.8. Moreover, based on structure, surface activity is not expected or predicted. The present substance is not intended to be used as a surfactant (i.e. not a desired property), and it does not contain groups (such as distinct polar and non-polar parts) indicating that it will have surface active properties in solution. Therefore, the study is deemed unnecessary.

Reason / purpose:
data waiving: supporting information
Reference

Low solubility (< 1 mg/L).

Equilibrium reached after 72h pre-incubation at 30°C + 42h equilibration at 20°C.

pH of saturated solution: 6.0.

Water solubility:
0.43 mg/L
at the temperature of:
20 °C

A fully reliable experimental study, conducted according to OECD/EU method and under GLP, is available. It is considered as a key study. The result is retained as key data.
