Description of key information
Additional information
MTDID 18990 is a UVCB material consisting of largely of diamides, triamides, and polyamides of fatty acid addition products. A small (<2%) contribution by monoamides of C18 fatty acids is present as well as residual 4,7,10-trioxa-1,13-tridecane-diamine. Given its vapor pressure it is unlikely to be present in the atmospheric compartmetn. Given water solubility and Koc, it is expected that upon release to the environment it would reside in soils and sediments.
Hydrolysis cannot practically be measured, but it given the structure and self-association hydrolysis is unlikely to contribute to fate. No biodegradation was observed in an OECD 301F test. It should be noted that, as per their respective registrations, the diamine used to manufacture this substance showed negligible results in a ready biodegradation study, with similar lack of degradation for fatty acid dimers and trimers. Biologically mediated hydrolysis of the amide bonds would therefore not have increased the biodegradation of this material. Monoamides of residual C18 monoacids contribute <2% of total weight of the material. While monoamides would be more amenable to degradation, their contribution to total composition is too small to have an impact on the result.
Due to high hydrophobicity (log Kow >11) and high molecular weight, materials derived from fatty acid dimers and trimers are unlikely to bioconcentrate. Monoamine materials are charged at physiological pH will have strong surfactant properties due to the charged, oxyamine head group linked to a C18 tail. Owing to the charged head group, bioconcentration is not expected. Residual diamine is water soluble and hydrophilic (log Kow -1.25). It does not bioconcentrate
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).
