Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 accordance with Regulation (EC) No 1907/2006, Annex IX, Section 9.2 and, Column 2, the soil simulation testing does not need to be conducted as the chemical safety assessment according to Annex I indicates that there is no need to investigate further the degradation of the substance and its degradation products. The risk characterization ratios (RCRs) of the chemical safety assessment are below 1, indicating that the risks are acceptable. Therefore, no biodegradation studies in soil will be provided. In addition, the substance does not have a high potential for adsorption to soil. The log Kow is low (log Kow < 3; see IUCLID Ch. 4.7). The estimated adsorption coefficients for the charged molecule is also low (measured log Koc = 1.5 at pH 7; see IUCLID Ch. 5.4.1).  Therefore, it is not considered necessary to conduct a soil simulation test and no biodegradation studies in soil will be provided.

Potential degradation products were predicted using Catalogic 301C v11.15 (OASIS Catalogic v5.13.1.156). 29 metabolites were predicted. Sixteen of these metabolites can be regarded as relevant based on their predicted quantity (> 0.001 mol/mol parent). Further details are given in IUCLID Ch. 5.2.1.

In addition, as the substance has been shown to be inherently biodegradable and all studies indicate the potential for rapid degradation within the environment (see IUCLID Ch. 5.2.1), no further testing on degradability is considered necessary.
