Description of key information
Additional information
The biodegradation of Tri-C18-22 (even numbered)-alkyl 2-hydroxypropane-1,2,3-tricarboxylate was not specifically determined.
However, data are available for a structurally related substance Tri (hexyl, octyl, decyl) citrate with the only difference in shorter carbon chain ester groups. The substance exhibited up to 67% biodegradation after 28 d in a ready biodegradability test. The biodegradation of the test substance reached 51% at the end of the 10-d window. But for UVCB substances the 10-day window condition should not be applied. In a study on inherent biodegradability the pass level of 70% was reached. The substance can be considered as readily biodegradable.
In accordance with column 2 of REACH annex IX, further degradation testing does not need to be conducted because direct or indirect exposition in soil is not probable.
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.
