Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Freshwater:
Water accommodated fractions of hydrocarbons, C10-C12, isoalkanes, <2% aromatics, did not produce a 50% effect (immobility) with Daphnia magna at a loading of 1000 mg/L after a 48-hour exposure. Therefore, the 48-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 48 hours. Therefore, the 48-hour LL0 for mortality is reported as 1000 mg/L. There was also no mortality in the control.
The water accommodated fraction (WAF) of hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, <2% aromatics, did not produce a 50% effect (immobility) with Daphnia magna at a loading of 1000 mg/L after a 48-hour exposure. Therefore, the 48-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 48 hours. Therefore, the 48-hour LL0 for mortality is reported as 1000 mg/L. There was also no mortality in the control. The water accommodated fraction (WAF) of hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics, did not produce a 50% effect (immobility) with Daphnia magna at a loading of 1000 mg/L after a 48-hour exposure. Therefore, the 48-hour LL50 is reported as >1000 mg/L. There was no mortality at the 1000 mg/L loading level after 48 hours. Therefore, the 48-hour LL0 for mortality is reported as 1000 mg/L. There was also no mortality in the control. The data from these four studies are used as read-across data to Raffinates (Fischer-Tropsch), C10-C25-branched hydrocarbon fluids. 
Marine:
The 100% water soluble fraction (WSF) of hydrocarbons, C10-C14, isoalkanes, cyclics, <2% aromatics, at a loading of 81,000 mg/L did not produce a 50% mortality with Mysidopsis bahia after a 96-hour exposure. Therefore, the 96-hour LL50 value is reported as >81,000 mg/L. There was also no mortality in the control. These data are used as read-across data to Raffinates (Fischer-Tropsch), C10-C25-branched hydrocarbon fluids.
