Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Study WAIVED. This substance is not directly applied to soil and based on its intended use will not enter the terrestrial environment. The indirect exposure of soil to this substance via sewage sludge is also of no concern based on the treatment of the sludge. In accordance with section 9.4 of REACH Annex IX and X, further tests do not need to be conducted if direct and indirect exposure of the terrestrial compartment is unlikely. This is further supported by the existence of macroinvertebrate data which shows no concerns. The substance is also not a PBT, vPvB and Risk Assessment RCRs are <1.

Additional information
Study WAIVED. This substance is not directly applied to soil and based on its intended use will not enter the terrestrial environment. The indirect exposure of soil to this substance via sewage sludge is also of no concern based on the treatment of the sludge. In accordance with section 9.4 of REACH Annex IX and X, further tests do not need to be conducted if direct and indirect exposure of the terrestrial compartment is unlikely. This is further supported by the existence of macroinvertebrate data which shows no concerns.
ECHA Chapter R.7B and R.7C guidance states that if the PEC/PNEC ratio is below 1, then no risk for the compartment is indicated, that the information available may be sufficient to conclude the assessment, and there is no need to perform further tests. In addition, ECHA Chapter R.7B guidance states that if the substance is not considered a PBT or vPvB candidate, then it is considered not necessary to conduct further testing on the compartment. Therefore, on the basis of a lack of potential exposure, and hence risk, and low risk demonstrated by the RCRs less than 1 based on EUSES modelling, and existing macroinvertebrate data which shows no toxicity, it is considered that the information available is sufficient and further testing is not required.
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.
