Description of key information
Biodegradation in water: Screening test: Key study: Based on the experimental results on test item butan-2-one O,O',O''-(methylsilanetriyl)oxime was determined not to be readily biodegradable. This result was supported by EPI-Suite, EPA (USA) / BIOWIN v4.10 calculation method.
Biodegradation in water: Simulation test: Data waiving (technically not feasible): In accordance with section 2 of REACH Annex XI, the simulation test study on water is technically not possible because the substance is hydrolytically unstable. The test item undergoes rapid hydrolysis (half-life < 1h) in aqueous to 2-butanone oxime and the corresponding methylsilanetriol. Moreover, silanetriols undergo continuous condensation reactions to produce higher molecular weight siloxanes which are considered biologically unavailable.
Biodegradation in sediment: Simulation test: Data waiving (study scientifically not necessary): In accordance with column 1 of REACH Annex IX, the sediment simulation test study does not need to be conducted as the substance and degradation products have no adsorption potential expected to sediment.
Biodegradation in soil: Data waiving (study scientifically not necessary): In accordance with column 1 of REACH Annex IX, the soil simulation test study does not need to be conducted as the substance and degradation products have no adsorption potential expected to soil.
Additional information
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.
