EC number: 293-261-7 | CAS number: 91052-99-2 A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of branched olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 105°C to 120°C (221°F to 248°F).

Description of key information
The terrestrial toxicity was predicted by a QSAR, the PETROTOX v4.0 computer model. PETROTOX is a well-documented and peer reviewed model that is widely used across the chemicals industry. The LL50 values for different terrestrial species range from 122 to 19823736 mg/ kg soil dw. The EL10 values for different terrestrial species range from 23.3 to 3797650 mg/ kg soil dw.
