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.

Additional information

There are two reliable experimental studies for photo degradation in air. The overall loss rate of acetone including photo dissociation and loss by reaction with OH radicals and the corresponding lifetimes were calculated for January, Equinox and July at 40 degree northern latitude. Lifetimes were 18.6 - 114.4 days. This is in accordance with the findings of the second study. The photo dissociation lifetime for 40°solar angle is 1/kdissoc = 14.8 days. Based on the weight of evidence and on the molecular structure acetone is resistant to hydrolysis. In water acetone may form the ketal by hydration, however ketal formation is reversible.
