Description of key information
Additional information
The substance belongs to the category "Hydrocarbons, C14-C20, aliphatics (=2% aromatics). The members of this category have been investigated using a category approach.
"Hydrocarbons, C14-C20, aliphatics (=2% aromatics)" are poorly soluble in water and made of constituents with various water solubilities. As a consequence, most studies are performed with "Water Accommodated Fractions" (WAFs) and the results must be expressed as "loading rates" instead of "concentrations".
Short-term toxicity to fish
Short-term toxicity studies showed that fish are the less sensitive group: no LL50 was determined and mortality was never observed, with concentrations ranging from 250 to 70 000 mg/l.
Long-term toxicity to fish
Petrotox calculations determined that all substances from "Hydrocarbons, C14 -C20, aliphatics (<= 2% aromatics)" were not toxic to fish. Results of computer modelling to estimate chronic toxicity in a 28 -day freshwater fish study, based on growth, show that the substance will not produce toxicity at or below its maximum attainable water solubility. These results are read-across to Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics
Short-term toxicity to aquatic invertebrates
Measured data are available for the registration substance in which the EL50 for Daphnia magna was found to be >100 mg/l.
Long-term toxicity to aquatic invertebrates
The 21-d NOELR for aquatic invertebrates (Daphnia magna) based on reproduction was found to be > 1000 mg/l according to Petrotox calculations. The experimental studies could not determine LL50. These results are read-across to Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics.
Toxicity to algae and cyanobacteria
Measured data are available for the registration substance in which the EL50 was found to be >100 mg/l and the NOELR was ≥100 mg/l.
Toxicity to microorganisms
"Hydrocarbons, C14-C20, aliphatics, =2% aromatics" were found to be not toxic for aquatic microorganisms (LC50 > 100 mg/L). Therefore the substance is considered not toxic for aquatic organisms. These results are read-across to Hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics
