Biodegradation in water and sediment: simulation tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: sediment simulation testing
- Data waiving:
- exposure considerations
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of sediment is unlikely
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
According to REACH Annex IX, Column 2, the exposure to sediment during manufacturing of the product as well as during its use for the sealant production and use by the customer is unlikely. - Transformation products:
- yes
- Details on transformation products:
- - Formation and decline of each transformation product during test:
The test substance rapidly degrades with a half-life time of <1 hour at 25 °C and form oligomers and polymers.
Oligomer and polymer molecules, due to their very big sizes and molecular weights are not capable to cross the biological membrane, so the uptake of the substance never occurs. - Endpoint:
- biodegradation in water: simulation testing on ultimate degradation in surface water
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with column 2 of REACH Annex IX, the study does not need to be conducted since the chemical safety assessment indicates that there is no need to investigate further the degradation of the substance and its degradation products. - Transformation products:
- yes
- Details on transformation products:
- - Formation and decline of each transformation product during test:
The test substance rapidly degrades with a half-life time of <1 hour at 25 °C and form oligomers and polymers.
Oligomer and polymer molecules, due to their very big sizes and molecular weights are not capable to cross the biological membrane, so the uptake of the substance never occurs.

Description of key information
Data waiving. Surface water: In accordance with column 2 of REACH Annex IX, the study does not need to be conducted since the chemical safety assessment according to Annex I indicates no need to investigate further the degradation of the substance and its degradation products.
Data waiving. Sediment: According to the column 2 of REACH Annex IX, the study does not be conducted since direct and indirect exposure of sediment is unlikely.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
