Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Due to the high water solubility of > 600 g/L, the vapor pressure of ≤ 12 Pa at 20 ºC, and the low to moderate adsorption potential, derived from a measured Koc-range of 316-1567 (log Koc 2.5 - 3.19), C12-14 AS Zn will mainly distribute into the water compartment. In water, sediment and soil the substance will rapidly biodegrade and therefore a prolonged exposure can be excluded. Since the substance C12-14 AS Zn contains max. 12% of Zn in the molecule, the effects of Zn are discussed below.
Environmental fate of zinc was described in the EU Risk Assessment Report for zinc metal (ECB, 2008). Zinc is an essential metal and occurs also naturally in environment. The natural concentrations of zinc are highly variable. Adsorption of zinc is determined by presence of different phosphates (WHO, 1996), hydroxides, clay minerals and organic matter (Cleven et al., 1993) and depends on the concentrations, pH, redox potential, salinity, nature and concentrations of complexing ligands and also the concentration of zinc. The smaller particle size of sediment, the higher accumulation of zinc in the sediments from surface water can be expected.
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.
