Description of key information
The test substance proved to be readily biodegradable (87% biodegradation after 28 d) and is fulfilling the 10-d window criterion.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradation of hexanoic acid, 3,5,5-trimethyl-, tin (2+)salt (2:1) was investigated in a study conducted according to OECD Guideline 301 F and EU Method C.4-D over a period of 28 days and using non-adapted activated sludge as inoculum.The test item proved to be readily biodegradable and is fulfilling the 10 d-window criterion (87% biodegradation after 28 d). The functional control reached the pass level >60% after 14 d. In the toxicity control containing both test and reference item 62% biodegradation based on ThOD occurred within 14 d thus indicating that the test item was not inhibitory at the concentration tested. All validation criteria of the guideline were fulfiled.
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.
