CAS number: 222721-94-0
The target substance
1,2,3-Propanetricarboxylic acid, 2-Hydroxy-,tris(C14-C15-alkyl)esters is
classified as readily biodegradable.
The ready biodegradability of the target
substance 1,2,3 -Propanetricarboxylic acid, 2 -Hydroxy-, tris(C14 -C15
-alkyl)ester) was determined with a non-adapted activated sludge over a
test period of 48 days in the Modified Sturm Test according to OECD 301
B. Based on this test the test item 1,2,3-Propanetricarboxylic acid,
2-Hydroxy-,tris(C14-C15-alkyl)esters can be considered as readily
Supportive data are available for the source
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 source substance can be considered as readily
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.
