EC number: 293-263-8 | CAS number: 91053-01-9 A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 170°C to 185°C (338°F to 365°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 predicted LL50 values for Folsomia candida ranged from 122 to 714802 mg/kg soil dw. The predicted LL10 values for Folsomia candida ranged from 23.3 to 136935 mg/kg soil dw.
