Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 295-443-1 | CAS number: 92045-61-9 A complex combination of hydrocarbons obtained by distillation from the product of a naphtha steam cracking process and subsequent catalytic selective hydrogenation of gum formers. It consists of hydrocarbons having carbon numbers predominantly in the range of C4 through C12 and boiling in the range of approximately 30°C to 230°C (86°F to 446°F).

Description of key information
Experimental data on Short Term Toxicity to Fish was available for 1 stream within this Category. The 96h LL50 was 1.1 mg/L (WAF).
Petrotox QSAR results for substances within the category for short term toxicity (EL50) for fish ranged from 5.54 -19.05 mg/L.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 1.1 mg/L
Additional information
All experimental short term toxicity to fish data came from ExxonMobil (2003).
CAS No 68513-69-9 and 68921-67-5: The 96-hour LL50 was reported to be 1.1 mg/L, and LC50 1.0 mg/L. The study was GLP compliant and followed a standard guideline, and is therefore considered reliable and suitable for use as a key study. Although the LC50 was reported to be 1.0 mg/L, as the test substance is a hydrocarbon stream with various components the reporting of a measured concentration does not relate to the concentration of a raw stream. The results reported as WAF were used instead as they better represent the potential toxicity of the test substance.
Petrotox QSAR results on substances within the category for short term toxicity (EL10) for fish had results ranged from 5.54 - 19.05 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
