EC number: 942-445-1 | CAS number: -
Renewable hydrocarbons, C15-C18, branched alkanes is poorly soluble in water and made of constituents with various water solubilities. As a consequence, most studies are performed with "Water Accomodated 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 for all substances from Renewable hydrocarbons, C15-C18, branched alkanes were not toxic to fish. Results of computer modelling to estimate chronicity 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.
Short-term toxicity to aquatic invertebrates
Short-term toxicity studies on aquatic invertebrates showed the low toxicity of the substance with a LL50>3000 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.
Toxicity to alghae and cyanobacteria
The NOELR for algae was reported to be 2580 mg/L in seawater.
Toxicity to microorganisms
"Hydrocarbons, C14-C20, aliphatics, ≤2% aromatics" covers Renewable hydrocarbons, C15-C18, branched alkanes, and they were found to be not toxic for aquatic microorganisms (LC50 > 100 mg/L). Therefore the substance is considered not toxic for aquatic organisms.
