Description of key information

Bioaccumulation: aquatic / sediment:

Using BCFBAF Program (v3.00) model of EPI suite 2017 the estimated bio concentration factor (BCF) for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS No. 70609-66-4) is 70.79 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical sodium 2-[(1-oxododecyl)amino]ethanesulphonate is non bioaccumulative in food chain.

Additional information

Bioaccumulation: aquatic / sediment:

Two different predicted data for the target compound sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS No. 70609-66-4) and supporting weight of evidence study for its read across chemical were reviewed for the bioaccumulation end point which are summarized as below:

In a prediction done by using BCFBAF Program (v3.00) model of Estimation Program Interface (EPI suite 2017) bio concentration factor (BCF) for sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS No. 70609-66-4) estimated was 70.79L/kg wet-wt at 25 deg. c.

Another prediction done by using Bio-concentration Factor (v12.1.0.50374) of (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017) module the Bio-concentration Factor at range pH 1-14 of the chemical sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS no.70609-66-4) estimated to be 1.0 dimensionless.

In a supporting weight of evidence study from Hazardous Substance Data Bank (HSDB, 2017) the BCF value of read across chemical Dodecyl sodium sulfate (CAS no.151-21-3) estimated was 71.0 dimensionless by using log Kow of 1.6 and regression derived equation and it is far less than 2000 criteria so it is concluded that read acroos chemical Dodecyl sodium sulfate is non bioaccumulative.

In another supporting weight of evidence study from same source as mentioned above (HSDB, 2017) the BCF value of read across chemical (dodecyloxy)sulfonic acid (CAS no.151-41-7) estimated was 71.0 dimensionless by using log Kow of 2.4 and regression derived equation and it is far less than 2000 criteria so it is concluded that read across chemical (dodecyloxy)sulfonic acid is non bioaccumulative.

On the basis of above results for target chemical sodium 2-[(1-oxododecyl)amino]ethanesulphonate (CAS No. 70609-66-4) (from EPI suite and ACD labs, 2017) and for its read across chemicals (From HSDB) it can be concluded that the BCF value of test substance sodium 2-[(1-oxododecyl)amino]ethanesulphonate ranges from 1 to 71.0 dimensionless which does not exceed the bioconcentration threshold of 2000, indicating that the chemical sodium 2-[(1-oxododecyl)amino]ethanesulphonate is expected to be non bioaccumulative in the food chain.
