Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
According to the ECHA guidance on PBT/vPvB assessment (version 3.0, 2017) the substance is regarded as being potentially persistent (P) or very persistent (vP), not bioaccumulative (B) or very bioaccumulative (vB) and not toxic (T). As the B/vB and T criteria is not fulfilled, the substance is therefore not a PBT or vPvB substance.
Persistence Assessment
The OECD 301B test conducted gave a result of 0 % degradation after 28 days and determined that the substance is not readily biodegradable. Therefore the substance is regarded as being potentially persistent (P) or very persistent (vP).
Bioaccumulation Assessment
Based on the weighted average log Pow of 1.84 and on the constituents’ log Pow values (of 1.15, 1.99 and 2.36 for 2-(tetrapropenyl)succinic acid, Monoester of 2-(tetrapropenyl)-succinic acid with propane-1,2-diol and Diester of 2-(tetrapropenyl)succinic acid with propane-1,2-diol, respectively), the substance does not fulfil the bioaccumulative (B) and very bioaccumulative (vB) criteria.
Toxicity Assessment
The substance does not fulfil the toxicity (T) criterion as it is not classified as H350, H340, H372, H373, H350i, H360 and/or H361, none of the acute aquatic ecotoxicity LC50 and EC50 endpoints are < 0.01 mg/L, the calculated weighted average log Pow of 1.84 is less than the trigger value of > 4.5, the chronic endpoint (derived for a 72 hr algal study) NOEC of 59.6 mg/l is greater than trigger value of <0.01 mg/l and there is no other evidence that suggests chronic toxicity (as identified by the substance meeting the criteria for classification: STOT RE 1, or STOT RE 2 according to the CLP Regulation).
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.
