Description of key information
Additional information
Results of the Calculation by EPI-Suite, EPA (USA) v3.20 / AopWin v1.92 estimate of Atmospheric Oxidation (25 deg C) [AopWin v1.92] for hydroxyl radicals reaction and half life:
Hydroxyl Radicals Reaction: OVERALL OH Rate Constant = 0.0422 E-12 cm3/molecule-sec
Half-Life = 253.700 Days (12-hr day; 1.5E6 OH/cm3).
The study shows that the substance is readily biodegradable.
In accordance with column 2 of REACH Annex VIII, the study of hydrolisis does not need to be conducted since the substance is readily biodegradable.
Photomineralisation of the substance was found after 17 hours: degradation by light: 6.6 % of the applied substance.
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.
