Description of key information

The ready biodegradability of the test item 1,2,3-Propanetricarboxylic acid, 2-Hydroxy-, tris(C12-C13-branched-alkyl)ester was determined with a non-adapted activated sludge over a test period of 49 days in the Modified Sturm Test.

The test item 1,2,3-Propanetricarboxylic acid, 2-Hydroxy-, tris(C12-C13-branched-alkyl)ester is classified as not readily biodegradable, but inherently biodegradable (without pre-adaptation) and with the potential for complete mineralization.

The ready biodegradability of the structurally related substance 1, 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 substance is classified as readily biodegradable.

The source substance 1 , Tri (hexyl, octyl, decyl)-citrate,  has a mean biodegradability in the CO2 Evolution Test according to OECD 301 B of 67% after 28 days.  For UVCB substances the 10-day window condition should not be applied. Therefore Tri (hexyl, octyl, decyl)-citrate is regarded as readily biodegradable.
