Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In the atmosphere, the thiocyanate salts are not likely to be degraded by reaction with hydroxyl and ozone radicals.
Key value for chemical safety assessment
Additional information
Degradation rates for the thiocyanates were calculated with the Atmospheric Oxidation Programme (AOPWIN v1.92a) based on structure activity relationships developed by Atkinson (1987). With a concentration of 500,000 OH-radicals/cm3, hydroxyl degradation rate constant of 0.000000 E-12 cm3/molecule-sec was calculated, and a degradation half-life of for the 3 thiocyanates could not be calculated. Because of the absence of acetylene and olefin structures in the molecules, reaction with ozone could not be estimated.
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.
