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

Description of key information

In accordance with column 2 of REACH Annex VII, the determination of surface tension (required in section 7.6) was waived. 
Surface activity is not the desired property of the substance and moreover based on the chemical structure tert.-Butylperoxy- 2-ethylhexanoat will not have surface activity and consequently no testing was required (ECHA CSR R7, 2008).
