PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence Assessment:
The ready biodegradability of the target 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 that test 1,2,3-Propanetricarboxylic acid, 2-Hydroxy-,tris(C14-C15-alkyl)esters is classified as readily biodegradable.
Therefore the substance is not very persistent (vP) or persistent (P).
Bioaccumulation Assessment:
1,2,3 -Propanetricarboxylic acid, 2 -Hydroxy-, tris(C14 -C15 -alkyl)ester) is not bioaccumulative (B) or very bioaccumulative (vB) based on results from a calculated bioconcentration (BCF) factor with EPISUITE software (EPIWEB 4.0).
The calculated BCF was 3.16 L/kg (regression-based estimate) and 0.893 L/kg (Arnot-Gobas upper trophic estimate). Therefore the BCF is well below 2000 L/kg, which is the criterion for not being considered B, and well below 5000 L/kg, which is the criterion for not being considered vB.
Toxicity Assessment:
1,2,3-Propanetricarboxylic acid, 2-Hydroxy-,tris(C14-C15-alkyl)esters or it´s degradation products are not classified as toxic according to Directive 67/548/EEC and the data on toxicity provided herein.
Summary and overall Conclusions on PBT or vPvB Properties:
The data on the properties of 1,2,3-Propanetricarboxylic acid, 2-Hydroxy-,tris(C14-C15-alkyl)esters do not meet the specific criteria detailed in Annex XIII and demonstrate that 1,2,3-Propanetricarboxylic acid, 2-Hydroxy-,tris(C14-C15-alkyl)esters is not a PBT or vPvB.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
