Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A biodegradation screening study indicate that Reaction product of fatty acids C14-18/C16-18 unsaturated with dihydrogendioxide and ammonia is readily biodegradable according to OECD criteria (> 80% biodegradation in 30 days while passing the 10-day window). Due to their ready biodegradability, hydrolysis is not expected to be a relevant degradation pathway for this substance.
Reaction product of fatty acids C14-18/C16-18 unsaturated with dihydrogendioxide and ammonia is water soluble (340 mg/L) and has a low log Kow value (log Kow = 1.48), which leads to a low adsorption potential (Koc < 1.25). Thus, the substance will tend to be mainly distributed into the water phase if entering the environment. However, as the substance is considered to be readily biodegradable, persistence in this compartment is not expected.
The ammonia component is expected to form salts with available anions under environmental condition. Volatilisation of ammonia into the athmosphere is expected to be of minor importance, due to the pka value of 9.23. Photolytic degradation and reaction with photolytically produced radicals in the troposphere are the expected pathways for the removal of atmospheric ammonia.
Bioaccumulation in aquatic organisms is unlikely since the substance has a low log Kow of 1.48, which assume that the substance will not cross biological membranes.
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.
