Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No relevant studies on terrestrial organisms are available for the substance.
According to Regulation (EC) 1907/2006, Annex IX, Section 9.4.1 to 9.4.3, Column 2, studies on the toxicity to terrestrial organisms do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
For the substance only industrial and professional uses with adequate risk mitigating measures are foreseen. Environmental exposure through widespread uses by consumers is excluded. Widespread uses by professionals will mostly take place indoors. In case of outdoor scenarios, risk mitigating measures are implemented to reduce unintended exposure to insignificant amounts. The substance is not supposed to be directly applied to soil. An indirect exposure to soil via sewage sludge transfer is unlikely since the substance is readily biodegradable (for details see IUCLID Ch. 5.2.1). For a substance being considered as „readily biodegradable“, it can be assumed that it will be biodegraded within the STP process and as a consequence a transfer to the soil compartment is not expected. In addition, adsorption to sewage sludge is not expected based on the low adsorption potential (see IUCLID Ch. 5.4.1); therefore, further reducing the risk of indirect transfer of the substance via sewage sludge.
In Annex XI, Section 3, it is laid down that testing in accordance with Annex IX may be omitted, based on the exposure scenario(s) developed in the Chemical Safety Report (“Substance-Tailored Exposure-Driven Testing”). In accordance with Annex XI, Section 3, it can be demonstrated in the risk assessment that the manufacture and the use of the substance do not pose an unacceptable risk for all environmental compartments as the risk characterization ratios (RCRs) of the chemical safety assessment are well below 1 for all compartments (see Chemical Safety Report Ch. 10).
Consequently, no tests on soil organisms are performed. The equilibrium partitioning method has been used for assessing the hazard to soil organisms in accordance with Annex IX, Section 9.4, Column 2 of Regulation (EC) No 1907/2006.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
