Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Acute Fish Toxicity:
Water accommodated fractions of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics were tested according to OECD 203 (limit test) and GLP, and produced a 96-h LL50 value of > 100 mg/L and a NOELR value of 100 mg/L for fathead minnow, Pimephales promelas (Hartwell, 2011). No mortality was observed in either the control or the treatment test systems.
Chronic Fish Toxicity:
The study was conducted according to ISO guideline 12890 using Danio rerio as test organism (Viktor, 2004). Embryos/larvae were exposed to six test concentrations of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics between 14 and 136 mg/L, and the effect parameters hatching time, survival time and deformations were followed. Since the test substance showed no effect on any of the investigated parameters, the NOEC value was determined to be > 136 mg/L.
Acute Invertebrate Toxicity:
Freshwater: Water accommodated fractions of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics were tested according to OECD 202 and GLP, and produced a 48-hour EL50 value > 100 mg/L and a NOELR value of 100 mg/L for Daphnia magna (Hartwell, 2011)
Marine: Water accommodated fractions of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics were tested according to OCSPP 85.1035 (limit test) and GLP, and produced a 96-hour LL50 value > 1000 mg/L and a NOELR value of 1000 mg/L for Mysidopsis bahia (Hartwell, 2011).
Chronic Invertebrate Toxicity:
There are no data available onlong-term toxicity to aquatic invertebratesof Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics.
Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics consist of hydrocarbon solvents with predominant carbon numbers in the range of C11 to C19. The constituents of this solvent are single isomers as well as mixed solvents of which the primary constituents are branched chain (iso-), and cyclic aliphatic hydrocarbons. Aromatic constituents, if present, represent less than 0.1% of the total volume.
N-paraffins are only present in very low concentrations (<1%).
The carbon numbers in the range of C11 to C19 and initial distillation points (IBP) characterize the source substances. The distillation range of the source substances ranges from 220°C to 350 degree Celsius although some solvents may contain higher boiling material. The benzene and sulphur contents of source substances are low, benzene levels for example are typically <3 ppm.
The toxicology and environmental fate and effects data show that source substances have a similar order of (eco-)toxicological and environmental fate properties as the target substance. Therefore, read-across is performed based on an analogue approach (for details please refer to the analogue justification which is attached in section 13 of the technical dossier).
Water accommodated fractions of hydrocarbons, C11-C13, isoalkanes, < 2% aromatics were tested according to OECD 211 (limit test) and GLP, and produced a 21-day NOELR value of 1 mg/L for Daphnia magna (ExxonMobil 2001). Water accommodated fractions of hydrocarbons, C13-C16, isoalkanes, cyclics, < 2% aromatics, were tested according to OECD 202 (section 2), and produced a 21-day EL50 value of > 5 mg/L based on adult immobilization and reduction in reproduction of Daphnia magna. These data are used as read-across data to Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics. Based on these data, Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics is not expected to exert chronic toxic effects to invertebrates at saturation.
Algal Toxicity:
Water accommodated fractions of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics were tested according to OECD 201 (limit test) and GLP, and produced a 72-hour EL50 value of > 100 mg/L and a NOELR value of 100 mg/L for Pseudokirchneriella subcapitata (Hartwell, 2011). No inhibition of growth was observed in either the control or the treatment test systems.
Toxicity to microorganisms:
There are no data available on toxicity to microorganisms of Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics.

Testing isododecane in a non-guideline study according to GLP with Pseudomonas putida did not result in inhibition of the respiration rate at the highest loading rate of 2 mL/L over an exposure period of 5 hours (Sasol, 1994).
For hydrocarbons, C11-C14, isoalkanes, cyclics, < 2% aromatics, a QSAR model was calculated for the toxicity to the protozoan Tetrahymena pyriformis, which resulted in a 48-h EL50 value of > 1000 mg/L based on growth inhibition (Concawe, 2010).
Hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, < 2% aromatics were tested according to OECD 209 (limit test) and GLP. The wastewater treatment plant activated sludge respiration inhibition 3-h EL50 value was > 100 mg/L (Pic, 1994).
These data are used as read-across data to Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics. Based on these data, Distillates (Fischer-Tropsch), 210-360 degree Celsius, hydrotreated, isoalkanes, cyclics, <0.1% aromatics is not expected to exert toxic effects to wastewater treatment organisms at saturation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
