(3R,5Z)-3-METHYL-5-CYCLOPENTADECEN-1-ONE

Surface tension

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.
