Description of key information

In accordance with column 2 of REACH Regulation (EC) No 1907/2006, Annex VII, the determination of surface tension (required in section 7.6) only needs to be conducted if based on structure of the substance surface activity can be predicted. Based on the structure of Poly-1,4-Diisopropylbenzene, no surface activity can be predicted and consequently no testing is required (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, EU-Document (2012)). In addition, the water solubility of the substance is < 1 mg/L at 20°C. Thus, determination of the surface activity is not required.
