Endpoint summary
Administrative data
Description of key information
There is data available for this substance. Additionally, key and supporting data is available for the following structural analogues: Hydrocarbons, C9-C10, n-alkanes, isoalkanes, cyclics, <2% aromatics, Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, <2% aromatics and Hydrocarbons, C10 -C14, isoalkanes, cyclics, <2% aromatics. The data is read across to these substances based on analogue read across and a discussion and report on the read across strategy is provided as an attachment in IUCLID Section 13.
The substances are poorly soluble and made of constituents with various water solubility. As a consequence, the exposures were performed with Water Accommodated Fractions (WAFs). Therefore, the results are based on nominal loadings.
There was no experimental data available for this substance or structural analogues for long-term toxicity to fish, long-term toxicity to aquatic invertebrates or toxicity to microorganisms. For these endpoints, the aquatic toxicity was estimated using the PETROTOX computer model (v4.0), which combines a partitioning model used to calculate the aqueous concentration of hydrocarbon components as a function of substance loading with the Target Lipid Model used to calculate acute and chronic toxicity of nonpolar narcotic chemicals. PETROTOX computes toxicity based on the summation of the aqueous-phase concentrations of hydrocarbon block(s) that represent a hydrocarbon substance and membrane-water partitioning coefficients (KMW) that describe the partitioning of the hydrocarbons between the water and organism.
According to the harmonised CLP legislation (2008), Annex VI, this substance is classified for the environment as aquatic chronic category 2 with the hazard statement H411: Toxic to aquatic life with long lasting effects.
Additional information
Key and supporting information is summarised below:
Short-term toxicity to fish
Hydrocarbons, C9-C10, n-alkanes, isoalkanes, cyclics, <2% aromatics presented a a 96-hour LL50 range of >10 to <30 mg/L and LL0 value of 1 mg/L for Oncorhynchus mykiss.
Hydrocarbons, C10-C13, n-alkanes, isoalkanes, cyclics, <2% aromatics presented a 6-hour LL50 value of >1000 mg/L and LL0 value of 1000 mg/L for Oncorhynchus mykiss.
Hydrocarbons, C9-C10, n-alkanes, isoalkanes, cyclics, <2% aromatics presented a 96-hour LL50 value of 50.9 mg/L for Oncorhynchus mykiss.
Water accommodated fraction of Alkanes, C10-13-iso- produced a 96-hour LL50value of >9.1 mg/L (nominal) with freshwater fish, Danio rerio. No mortality was recorded at the limit loading rate.

The aquatic toxicity was estimated using the PETROTOX computer model (v4.0), which combines a partitioning model used to calculate the aqueous concentration of hydrocarbon components as a function of substance loading with the Target Lipid Model used to calculate acute and chronic toxicity of nonpolar narcotic chemicals. PETROTOX computes toxicity based on the summation of the aqueous-phase concentrations of hydrocarbon block(s) that represent a hydrocarbon substance and membrane-water partitioning coefficients (KMW) that describe the partitioning of the hydrocarbons between the water and organism.
