Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

The PBT Assessment is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2014).

Persistence (P) Assessment:

The substance Fatty acids, C18 unsaturated, ethyl & methyl esters (EC 941-981-3) is readily biodegradable. Therefore, the substance is not expected to be persistent in the environment and it does not meet the Persistent (P) or very Persistent (vP) criteria.

Bioaccumulation (B) Assessment:

Due to the low water solubility, rapid environmental biodegradation a relevant uptake and bioaccumulation in aquatic organisms is not expected. This is supported by low BCF values <2000 L/kg (BCFBAF v3.01, Arnot-Gobas, including biotransformation, upper trophic). Based on the available information, the substance does not meet the B or vB criteria.

Toxicity (T) Assessment:

Fatty acids, C18 unsaturated, ethyl & methyl esters (EC 941-981-3) is not considered to be toxic. Long-term toxicity testing with Daphnia magna resulted in a NOELR (21 d) of ≥ 100 mg/L (read across). The substance is furthermore not classified as carcinogenic, mutagenic or toxic for reproduction nor is there any evidence of chronic toxicity according to the 6th ATP of Regulation (EC) No. 1272/2008 (CLP). The criteria for “T” are therefore not met.
