Description of key information

Surface activity is not the desired property of 1,1-bis(tert-butylperoxy)cyclohexane and moreover based on the chemical structure the substance will not have surface activity.

Key value for chemical safety assessment

Additional information

In accordance with column 2 of REACH Annex VII, determination of surface tension (required in section 7.6) only needs to be conducted if based on the structure of the substance surface activity can be predicted. Based on the structure of the substance, no surface activity can be predicted (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (May 2008)) and consequently no testing is required. In addition, testing is technically not possible due to the very low water solubility( below 1mg/L) of the test item.
