Remarks on result:
other: QSAR calculation

The surface tension of 2,6 -di-tert-butylphenol is 30.1±3 mN/m

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 surface activity is not a desired property of the material

Description of key information

Paragraph R7.1.6.1 contained within Chapter 7.A, Endpoint Specific Guidance, states that a study does not need to be performed if the test substance, based upon structure, is not expected or predicted to have surface activity or; or surface activity is not a desired property of the material.  For 2,6-di-tert-butyl phenol surface activity is not a desired property and is not predicted, as shown using the Q(S)AR ACD (30.1±3 mN/m).

Based upon the above reasons it is therefore considered unnecessary to perform a test for surface tension for 2,6-di-tert-butyl phenol.

Key value for chemical safety assessment
