Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The testing on Adsorption/Desorption according to OECD Guideline 121 resulted in a Koc of 1.7. Thus, UAX-1179 has a low potential to be adsorbed by organic carbon to soil and sediment particles.
Key value for chemical safety assessment
Additional information
The testing on Adsorption/Desorption of the test substance UAX-1179 (CAS: 351197-46-1) was performed according to the OECD Guideline 121 “Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)” (Tognucci, 2002). Different reference substances with known log Koc values were used for calibration (log Koc vs. log capacity factor k’). The test substance was tested 3 times and resulted in retention times of 2.98-2.99 min with a corresponding capacity factor of 0.81-0.82. The log Koc was extrapolated to be 0.24. The Koc was calculated to be 1.7. This value indicates that the test substance UAX-1179 has a low potential to be adsorbed by organic carbon to soil and sediment particles.
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.
