Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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

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
