Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
There is no data available for Hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%). However, data is available for structural analogues,
Hydrocarbons, C11-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) and Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) and presented in the dossier. This data is read across to Hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%)based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.
Acute Fish Toxicity:
Water accommodated fractions of hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) did not cause acute toxicity to fish with rainbow trout, Oncorhynchus mykiss at a nominal loading of 1000 mg/L. These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Chronic Fish Toxicity:
Hydrocarbons, C11-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%)did not cause toxicity to fish ina 21-day toxicity study with Brachydanio rerio following standard test guidelines at a nominal loading of 5000 mg/L.These results indicate that hydrocarbons, C11-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%)is not expected to be chronically toxic to fish.These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Acute Invertebrate Toxicity:
Water accommodated fractions of hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) did not cause acute toxicity to the freshwater invertebrate, Daphnia magna at a nominal loading of 1000 mg/L. These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Chronic Invertebrate Toxicity:
Hydrocarbons, C11-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%) did not cause toxicity in a 21-day toxicity study with Daphnia magna following standard test guidelines at a nominal loading of 1400 mg/l, with a NOELR of 17 mg/L (based on inhibition of reproduction).These results indicate that hydrocarbons, C11-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%)is not expected to be chronically toxic to freshwater invertebrates. These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Algal Toxicity:
Water accommodated fractions of hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2 -30%) did not cause acute toxicity to the freshwater green algae, Pseudokirchneriella subcapitata, at a nominal loading of 1000 mg/L. These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Microorganisms Toxicity:
Water Accomodated Fractions of hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%), did not inhibit microbial respiration in a sludge sample at a concentration of 1000 mg/L. Therefore, Hydrocarbons, C16-C20, n-alkanes, isoalkanes, cyclics, aromatics (2-30%), is not expected to adversely affect microbial activity in a wastewater treatment plant. These data are used as read-across data to hydrocarbons, C12-C18, isoalkanes, cyclics, aromatics (2-30%).
Additional information
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.
