EC number: 309-939-3 | CAS number: 101631-14-5 A complex combination of hydrocarbons obtained by distillation of steam cracking heavy residues. It consists predominantly of highly alkylated heavy aromatic hydrocarbons boiling in the range of approximately 250°C to 400°C (482°F to 752°F).

Description of key information
The surface tension of an aqueous preparation (90% saturation) of one stream within this Category is 72.1 mN/m at 20°C, indicating that these streams are not surface active.
Key value for chemical safety assessment
- Surface tension:
- 72.1
- in mN/m at 20°C and concentration in mg/L:
- 34.2
Additional information
Data from BASF (2007) are available for one of the streams in this category (98072-36-7: 72.1 mN/m at 20°C). The data will be read across to all category members. This study was conducted to a standard guideline and according to GLP and so is considered fully reliable for use as a key study.
The key value has been completed using the only available data for streams in this category. The surface tension result was given at 90% saturation and this has been converted to a concentration in mg/L by applying this factor to the water solubility result for this stream.
