- Reference substance:
- 0286 OLEOYLSARKOSINSÄURE, K-SALZ
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment of the substance is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2014).
Persistentcy assessment
Based on the available data, Potassium (Z)-N-methyl-N-(1-oxo-9-octadecenyl) aminoacetate (CAS 76622-74-7) is considered to be readily biodegradable. Thus, the substance does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulation
The substance is readily biodegradable and thus not persistent (P or vP). Therefore, no B-assessment was carried out since it is only required if the substance fulfills the P or vP criteria, according to the guideline (Guidance on Information Requirements and Chemical Safety Assessment Chapter R.11: PBT/vPvB assessment, 2014).
Toxicity
For the substance Potassium (Z)-N-methyl-N-(1-oxo-9-octadecenyl) aminoacetate (CAS 76622-74-7) the available acute effect concentrations are ≥ 0.1 mg/L (fish, aquatic invertebrates, algae) and the chronic effect concentration (algae) is ≥ 0.01 mg/L. The substance is readily biodegradable and has a log Kow < 4.5. Therefore, the criteria set out in Annex XIII of Regulation (EC) No 1907/2006 are not met and the test substance is not considered to meet the T criterion.
In conclusion, the substance is not PBT/vPvB.
