Results and discussion

Applicant's summary and conclusion

Interpretation of results (migrated information): no bioaccumulation potential based on study results
The relevant available data on Amines, N-tallow alkyltrimethylenedi-, propoxylated was analyzed to assess its potential toxicokinetic behaviour. The UVCB consists of different compounds. Most of the constituents are n-alkane-dipropylene triamines that are partly or fully propoxylated and contain primary, secondary or tertiary amine groups which are positively charged at in the physiological pH range. Overall the absorbance is expected to be low, while the metabolisation of amines common reactions of xenobiotic metabolism. Therefore a tendency for bioaccumulation is not expected. Metabolites will be excreted both via urine and bile (feces) depending on the size and charge of the molecules.
