Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The substance belongs to the category "Hydrocarbons, C14-C20, aliphatics (≤2% aromatics) and has been investigated using a category approach (see document attached to IUCLID section 13 for read-across justification).

"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 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 "Hydrocarbons, C14 -C20, aliphatics (<= 2% aromatics)" 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 algae and cyanobacteria

The NOELR for algae was reported to be 2580 mg/L in seawater.

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.
