Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Applicant's summary and conclusion

The toxicokinetics behaviour derived from available substance data might make further testing unnecessary in terms of predictability of other properties. In accordance with this approach (specified in “Guidance on Information Requirements and Chemical Safety Assessment”, Chapter R7c, Section R7.12.2), the report of Illing (unpublished report, 2006) can be taken into account and allows a qualitative judgement of the toxicokinetic properties of the test substance: Hydrocarbons are absorbed through the lung and the gastro-intestinal tract. They are widely distributed and excreted in urine or in exhaled air, depending on volatility. They are metabolised by ¿- or ¿-1 oxidation to the alcohol and then to the fatty acid. Fatty acids derived from hydrocarbons are likely to enter intermediary metabolism (including ß-oxidation) and be excreted in bile urine and exhaled air (as carbon dioxide) (Illing 2006). In addition 'Kerosine (Fischer-Tropsch), full range, C8-16 - branched and linear' has a measured log Kow of >6.5 and chemicals with log Kow >5 can pass through the stratum corneum but is limited by low water solubility in their ability to enter the bloodstream. However the irritating /defatting effects are likely to enhance dermal penetration.
