Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 soil microorganisms toxicity studies were available for the test substance.
Key value for chemical safety assessment
Additional information
The supported uses for this test substance are for industrial applications with no direct application to the terrestrial compartment. Indirect exposure to the terrestrial compartment via volatilization and redeposition would be negligible based on physical/chemical parameters and fugacity modeling. Fugacity modeling in STP suggests that the fraction of the emission directed to water, sludge, and air is 28.5%, 67.2% and 4.3%, respectively. In addition, this substance has been shown to undergo some degradation under test conditions that are less than optimal for biodegradation. Thus, based on the assumption of no direct application to soil and the physical/chemical characteristics of this substance it is anticipated that exposure to the terrestrial compartment would be negligible. Furthermore, using a PNECsoil calculated via the equilibrium partitioning method, the PEC/PNECsoil ratio for this substance is substantially <1. Therefore, soil microorganisms toxicity testing for this substance is waived.
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.
