Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Currently viewing:

Administrative data

PBT assessment: overall result

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

Persistance:

The test substance was tested for ready biodegradability in the Carbon Dioxide Evolution Test (OECD 301B). Based on the rate of biodegradation of 80-90 % CO2/ThCO2 at the end of exposure the test substance can be evaluated as readily biodegradable in this test.

Bioaccumulation:

Not B/vB based on the BCF <= 2000 L/kg:

BCF was calculated with EPI suite, recognizing the biotransformation of the esters, the BCF values are:

Nonyl methacrylate Cas: 2696-43-7

Log BCF (regression-based estimate): 1.73 (BCF = 53.2 L/kg wet-wt)

Biotransformation Half-Life (days) : 0.471 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic): 2.28 (BAF = 193 L/kg wet-wt)

Log Kow used by BCF estimates: 5.20

Estimated Log BCF = 1.726 (BCF = 53.24 L/kg wet-wt)

 

Decyl methacrylate Cas: 3179-47-3

Log BCF (regression-based estimate): 2.05 (BCF = 112 L/kg wet-wt)

Biotransformation Half-Life (days) : 0.649 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic): 2.40 (BAF = 251 L/kg wet-wt)

Log Kow used by BCF estimates: 5.70

Estimated Log BCF = 2.050 (BCF = 112.3 L/kg wet-wt)

 

Undecyl methacrylate Cas: 16493-35-9

Log BCF (regression-based estimate): 2.37 (BCF = 237 L/kg wet-wt)

Biotransformation Half-Life (days) : 0.894 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic): 2.48 (BAF = 303 L/kg wet-wt)

Log Kow used by BCF estimates: 6.19

Estimated Log BCF = 2.374 (BCF = 236.7 L/kg wet-wt)

Toxicity:

The test substance do not meet the criteria to be classified as T substance according to Annes XIII of REACH Regulation (EC) No 1907/2006.
