- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 306 (Biodegradability in Seawater)
- GLP compliance:
- yes
- Oxygen conditions:
- aerobic
- Inoculum or test system:
- natural water: marine
- Duration of test (contact time):
- >= 5 - <= 28 d
- Initial conc.:
- 1.266 mg/L
- Based on:
- test mat.
- Parameter followed for biodegradation estimation:
- DOC removal
- Reference substance:
- benzoic acid, sodium salt
- Preliminary study:
- yes, performed.
- Key result
- Parameter:
- % degradation (DOC removal)
- Value:
- 64.1
- Sampling time:
- 28 d
- Parameter:
- % degradation (DOC removal)
- Value:
- 39
- Sampling time:
- 5 d
- Parameter:
- % degradation (DOC removal)
- Value:
- 54.1
- Sampling time:
- 14 d
- Parameter:
- % degradation (DOC removal)
- Value:
- 64.3
- Sampling time:
- 21 d
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- After 28 days of analysis, the Test Item was 64,1 % degraded. The Test Item is therefore considered readily biodegradable.
- Executive summary:
A sample of ALKANOLAMINE FATTY ESTER COMPOUNDS was in this study assessed for biodegradation properties by exposing the substance to micro-organisms in natural seawater. The test was carried out according to Lamberti S.p.A. POS 0300 which is an extract of the OECD Guideline, OECD 306 (Biodegradation in seawater). After 28 days of analysis, the Test Item was 64,1 % degraded. The Test Item is therefore considered readily biodegradable.

Description of key information
A sample of ALKANOLAMINE FATTY ESTER COMPOUNDS was in this study assessed for biodegradation properties by exposing the substance to micro-organisms in natural seawater. After 28 days of analysis, the Test Item was 64,1 % degraded. The Test Item is therefore considered readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- marine water
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.
