Description of key information
Additional information
Phototransformation in air:-
The atmospheric oxidation half-life of4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one was estimated using the level III multimedia model. The overall persistence (Po) for4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-onein air is 44 days using the default emission scenario of the model. The estimated atmospheric oxidation estimates persistence based on a standard release scenario emitting equal amounts to soil, water, and air. It was estimated that the substance is not persistent in air medium as the half life period of4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one in air is only 0.021 days. However, since the percentage of4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one in air medium is 0 % it can be concluded that4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-oneis unlikely to be found in the atmosphere upon release in the environment.
Hydrolysis :
The Hydrolysis rate constant of 4-(2,6,6-trimethylcyclohex-1-ene-1-yl)-but-3-ene-2-one was estimated to be 0.0000000002385475 (238.5475 E-12 ) cm3/molecule-sec. at half life of the 0.538 Hrs. The estimated half life of the substance indicates that the substance is rapidly hydrolysable.
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).
