Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No terrestrial toxicity data are available.  The substance has demonstrated no hazardous properties in mammalian toxicity and aquatic ecotoxicity testing, and significant exposure of the soil compartment to the substance is considered unlikely; therefore, terrestrial toxicity studies are not needed.

Key value for chemical safety assessment

Additional information

The provision for toxicity to soil macroorganisms testing is contained within Column 1 of Annex IX of REACH. Column 2 of this Annex, describing the Specific Rules for Adaptation from Column 1, states:

"These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely."

Direct exposure of the soil compartment to the substance from its manufacture and use (see IUCLID Section 3) is considered negligible. Indirect exposure of the soil compartment might be possible via the spreading of sludge from sewage treatment plants (STPs) to land. However, loss of the substance to STPs during manufacture, and disposal of the substance to STP during use and end of life, is expected to be minimal. During manufacture, all necessary measures are taken to prevent releases to the water table, including no water washing of equipment and the use of waste water traps to limit release due to accidental spillage and rain water run-off. The substance is used as an additive in fuel; therefore, its end of life is its incineration.

The substance is also readily biodegradable (see IUCLID Section 5.2), further limiting the amount of intact substance that might be contained within sewage sludge applied to land. Consequently, it is reasonable to conclude that significant exposure of the soil compartment is unlikely.

The substance has also demonstrated no hazardous properties in mammalian toxicity and aquatic ecotoxicity testing. This further supports the notion that the substance does not represent a threat to terrestrial ecology and, in accordance with the Standard Information Requirements laid down by REACH (Annexes VII to X), terrestrial toxicity studies do not need to be conducted.
