Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), information regarding phototransformation in air, as well as in water and soil, is not mandatory.
JE Wynfield Rhodes (1934) provides a reliable study where the equilibria between acetone oxime, acetone and hydroxylamine in dilute aqueous solution (approx 1%) at pH between 2.4 and 6.8 and at a temperature of 49.7 degC was measured. It was concluded that the hydrolysis constant is approximately 16 x 10-6 in neutral conditions but increases somewhat (up to 4 times) when the solution becomes very acid. However, thehalf-life was not determined.
Environment Canada published data regarding the hydrolysis of the analogue substance, butanone oxime, in 2010. The information shows that the analogue, butanone oxime is degraded by 14% over a 4 -day window at a pH of 7 and a temperature of 20oC due to hydrolysis. A hydrolysis half-life for acetone oxime of 18.5 days is estimated, based on available evidence, including read-across arguments.
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.
