Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The water accommodated fraction of hydrocarbons, C12-C16, isoalkanes, cyclics, <2% aromatics, produced a 96-hour LL50 value of >87,556 mg/L and LL0 value of 87,556 mg/L to the fish, Oncorhynchus mykiss. No mortality was observed in either the control or treatment systems. These data are used as read-across data to hydrocarbons, C14-C19, isoalkanes, cyclics, <2% aromatics.
Additional data from a read-across substance supports that hydrocarbons, C13-C16, isoalkanes, cyclics, <2% aromatics does not cause acute aquatic toxicity to fish. The water accommodated fraction of hydrocarbons, C14-C18, n-alkanes, isoalkanes, cyclics, <2% aromatics, produced a 96-hour LL50 value of >250 mg/L and LL0 value of 250 mg/L with Danio rerio (Ex-Brachydanio rerio). No mortality was observed in either the control or treatment systems. Although these two substances are analogs to hydrocarbons, C14-C19, isoalkanes, cyclics, <2% aromatics, they have considerable overlap in carbon number. Additionally, although the second analog also contains normal hydrocarbons, which are not found in hydrocarbons, C14-C19, isoalkanes, cyclics, <2% aromatics, because their toxicological mode of action is the same as isoalkanes and cycloalkanes, they would be expected to exhibit the same degree of toxicity - or in this case, the lack of acute toxic effects.

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.
