Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In Annex X, Section 9.5.1, Column 2 of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity testing on sediment organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects on sediment organisms.
The Substance is biodegradable based on an enhanced ready biodegradability test passing the test level of 60% CO2/ThCO2 but not meeting the 10-day window (BASF SE, 2012; see IUCLID Ch 5.2.1); therefore, the substance is assessed to be not P/vP. The substance is also not B/vB based on the low log Kow (log Kow < 3, see IUCLID Ch. 4.7). The substance is not acutely hazardous to the aquatic environment; however, the substance is classified as chronically hazardous (Category Chronic 3) based on the acute toxicity to fish.
The adsorption potential of the substance is low (log Koc and log Kow < 3; see IUCLID Ch. 5.4.1). In addition, the substance has a high water solubility (see IUCLID Ch. 4.8). Hence, an adsorption to activated sludge, suspended matter or sediment particles is unlikely and a transfer to the sediment compartment is unlikely.
As sediment is not an environmental compartment of concern, no test on sediment toxicity is performed. The equilibrium partitioning method has been used for assessing the hazard to sediment organisms.
