Endpoint summary
Administrative data
Description of key information
There is data available for this substance. Additionally, key and supporting data is available for structural analogues. The data is read across to this substance 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.
According to the harmonised CLP legislation (2008), Annex VI, this substance is classified for the environment as aquatic chronic category 4 with the hazard statement H413: May cause long lasting harmful effects to aquatic life.

Long-term toxicity to fish
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.

Isododecane (a 90% saturated solution) did not produce a 50% effect (immobility) withDaphnia magnaafter a 48-hour exposure. The saturated solution of test substance was developed by adding 1 g/L and using the filtered aqueous phase. Therefore, the 48-hour EL50 can ony be reported as >90% of a saturated solution of the test substance. Since the analytical results were below the limit of detection, 10 ug/L, the results cannot be quantified based on either a loading or concentration basis.
