Waiving
Key value for chemical safety assessment
- Koc at 20 °C:
- 24.8
Additional information
According to the REACH Regulation (EC n. 1907/2006), Annex VIII, Column 2, the study does not need to be conducted when the physicochemical properties the substance can be expected to have a low potential for adsorption (log Kow =0.72 at pH=7 and at T=25 °C) or the substance and its relevant degradation products decompose rapidly . Both criteria for waiving adsorption/desorption screening are fulfilled for Tris(ethyl acetoacetato-O1',O3)aluminium.
A predicted value for partition coefficient organic carbon-water was calculated by EUSES 2.1.2 Koc = 24.8 l/kg. This value was used by CHESAR for chemical safety assessment. Considering this predicted value, a low adsorption potential is expected. As reported in ECHA Guidance Chapter R.7b: in general substances with a Koc <500 – 1000 l/kg are not likely sorbed to sediment (SETAC 1993).
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.
