Description of key information

Bioaccumulation: aquatic / sediment

BCFBAF model of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical 1-Propanaminium, 3 -amino-N-(carboxymethyl)-N,N- dimethyl-, N-coco acyl derivs., hydroxides, inner salts (CAS No. 61789 -40 -0). The bioconcentration factor (BCF) of 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts was estimated to be 70.79 L/kg whole body w.w (at 25 deg C) which does not exceed the bio concentration threshold of 2000, indicating that the chemical 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts is not expected to bioaccumulate in the food chain.

Additional information

Bioaccumulation: aquatic / sediment

Various predicted data for the target compound 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts (CAS No. 61789-40-0) and supporting studies for its structurally similar read across substance were reviewed for the bioaccumulation end point which are summarized as below:

 

In a prediction done using the BCFBAF Program of Estimation Programs Interface was used to predict the bioconcentration factor (BCF) of test chemical 1-Propanaminium, 3 -amino-N-(carboxymethyl)-N,N- dimethyl-, N-coco acyl derivs., hydroxides, inner salts (CAS No. 61789 -40 -0). The bioconcentration factor (BCF) of 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts was estimated to be 70.79 L/kg whole body w.w (at 25 deg C).

 

In an another prediction done by usingChemspider database, the bioconcentration factor (BCF) of test chemical 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts (CAS no. 61789 -40 -0). The bioconcentration factor of test substance 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts was estimated to be 4.18 at both pH 5.5 and 7.4, respectively.

 

In a supporting study from authoritative databases (HSDB and Pubchem, 2017) for the test item,the bioaccumulation study in fish was conducted for estimating the BCF (bioaccumulation factor) value of test chemical. The bioaccumulation factor (BCF) value was calculated using a log Kow of 5.82 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 600 dimensionless.

 

For the test item, the bioaccumulation study in fish was conducted for estimating the BCF (bioaccumulation factor) value of test chemical (HSDB, 2017). The bioaccumulation factor (BCF) value was calculated using a log Kow of 5.13 and a regression-derived equation. The estimated BCF (bioaccumulation factor) value of test chemical was determined to be 48 dimensionless.

 

On the basis of above results for target chemical 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts(from modelling databases,2018), it can be concluded that the BCF value of test substance 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts ranges from 4.18 –70.79, respectively which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 1-Propanaminium, 3-amino-N-(carboxymethyl)-N,N-dimethyl-, N-coco acyl derivs., hydroxides, inner salts is not expected to bioaccumulate in the food chain.
