Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
The atmospheric oxidation half-life of Eicosanoic acid was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of Eicosanoic acid in air is 0.62 days. This indicates that Eicosanoic acid is easily phototransformed in air.
OVERALL OH Rate Constant =0.000000000025cm3/molecule-sec.

Hydrolysis
The Hydrolysis rate constant of Eicosanoic acid is estimated to be 0.0000000000253065 cm3/molecule-sec. at half life of 5.072 hrs.The estimated half life of the substance indicates that the substance is moderately hydrolysable.
Phototransformation in water
No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.
Phototransformation in soil
No experimental data available. As this study is not a standard information requirement in REACH and there is no indication from the CSA on the need to investigate further the fate and behaviour of the substance (Annex X requirement), no further testing is considered necessary.
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.
