Description of key information
Key value for chemical safety assessment
Additional information
In accordance with Section 3 of REACH Annex XI, Substance-tailored exposure driven testing; simulation testing on ultimate degradation in surface water, information requirement 9.2.1.2 in Annex IX, may be omitted based on the exposure scenarios developed in the Chemical Safety Report. See supporting exposure assessment information (CSR Chapter 9).
Sediment simulation testing does not need to be conducted as there is no direct or indirect exposure to sediment for this test substance. In accordance with Column 2 adaptation statement of REACH Annex IX, information requirement 9.2.1.3, sediment simulation testing does not need to be conducted as there is no direct or indirect exposure to sediment. A log Koc or log Kow value ≥ 3 is used as a trigger value for sediments effects assessment (Section R.7.8.7, Guidance on information requirements and chemical safety assessment, Chapter R.7B, Endpoint-specific guidance, May 2008). Both the log Koc (0.59) and the log Kow (-0.09) for 4-aminophenol are below the level of concern for potential adsorption to sediment.
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.
