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
According to REACH Annex VII/column 2, the study needs only to be conducted if based on structure, surface activity is expected or can be predicted.
The present substance is not intended to be used as a surfactant (i.e. not a desired property), and the chemical structure does not contain groups (such as distinct polar and nonpolar parts) indicating that it will have surface-active properties in solution. Therefore, the study is deemed unnecessary.
Moreover, the water solubility is expected ca or < 1 mg/L, which supports that the test does not need to be conducted.
Cross-reference
Reason / purpose for cross-reference:
data waiving: supporting information
Reference

The substance is considered to be slightly soluble in water.

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

A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite restrictions on experimental details, it is considered as a key study, and the result is retained as key data.
