Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A waiver is requested for 9.5.1 Long-term testing for sediment organisms as the test substance is readily biodegradable, so exposure of the sediment compartment is unlikely. Moreover, the Chemical Safety Assessment using PNECsediment based on equilibrium partitioning shows no concern.
Key value for chemical safety assessment
Additional information
- A waiver is requested for 9.5.1 Long term testing for sediment organisms based on column 2 of Annex X of Regulation (EC) No 1907/2006.
1) The chemical safety assessment for linalool using equilibrium partitioning does not indicate a need to investigate further the effects of the substance and/or relevant degradation products on sediment organisms. The substance is readily biodegradable so exposure of the sediment compartment is unlikely. Therefore, a study on the long-term effects on sediment organisms is not provided.
2) Waiving of a long-term toxicity study to any sediment organisms is justified based on the actual outcome of the exposure assessment of all identified uses and the risk characterization for all wide dispersive uses. Details on the risk characterization are provided in the Chemical Safety Report/Asssessment for each individual use and also a summary for all wide dispersive uses in Chapter 10.2. There is no risk to sediment organism, in fact all RCRs are below 1. For this reason there is no indication that a long-term toxicity study to sediment organisms is necessary.
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.
