Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
PBT/vPvB criteria and justification
Persistence Assessment
Amides, C16-C18 (even numbered) is readily biodegradable in accordance with the definition given in the OECD Guidelines for the Testing of Chemicals.
Therefore, amides, C16-C18 (even numbered) is not persistent and does not meet the P criterion.
Bioaccumulation Assessment
In contrast to a calculated log KOW of > 6.5, which indicates a potential of the substance to bioaccumulate, a real bioaccumulation potential in the aquatic environment is not expected.
Due to the very low water solubility (< 0.1 mg/L) of Amides, C16-C18 (even numbered) and the ready biodegradability it is not likely that the substance can be found in the aquatic environment at high concentrations. Data from acute and chronic studies indicate that the substance is not toxic to aquatic organisms (algae, daphnia, fish) in the range of water solubility. Additionally, a bioaccumulation test is technically hardly feasible due to the high insolubility of the test substance and is not necessary due to the nonhazardous character of the test substance.
Additional information about this endpoint could be gathered through BCF calculation using BCFBAF (v3.00), a subroutine of the EPI Suite™ computer program. The BCF estimated value for the components of Amides, C16-C18 (even numbered), based on whole body wet weight, was between 115 -513, which is clearly below the trigger value of a BCF of greater than 2000.
In conclusion, Amides, C16-C18 (even numbered) does not meet the B criterion.
Toxicity Assessment
Amides, C16-C18 (even numbered) shows no toxicity in the range of water solubility.
All data give comparable results for fish, invertebrates and aquatic plants.
The substance is not classified as carcinogenic, mutagenic or toxic for reproduction nor is there any evidence of chronic toxicity, as identified by the classifications: T, R48, or Xn, R48 according to Directive 67/548/EEC.
Therefore, Amides, C16-C18 (even numbered) does not meet the T criterion
8.1.2. Summary and overall conclusions on PBT or vPvB properties
Overall conclusion: Amides, C16-C18 (even numbered) is not a PBT or vPvB substance.
