Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- weight of evidence
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Data are being assessed for the use in a category approach. Available information are being judged as reliable with restrictions since it was conducted by a modeled and measured data.
- Remarks:
- Data are being assessed for the use in a category approach. Available information are being judged as reliable with restrictions since it was conducted by a modeled and measured data.
- Justification for type of information:
- Important considerations for the read-across were:
Sodium Olivoyl Glutamate (the target chemical) has similar physico-chemical properties as the others members:
- "Aliphatic acid category" (the source chemicals);
- "Amino acid alkyl amides category" (the source chemicals);
- Sodium oleoyl glutamate (the source chemicals);
Key points are that the members share:
- the same structural features
- similar metabolic pathways
- common levels and mode of human health related effects
- function. - Qualifier:
- no guideline available
- Principles of method if other than guideline:
- not specified
- GLP compliance:
- not specified

- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Biodegradation studies or model estimations for single and multi-component aliphatic acids generally confirm that the extent of biodegradation observed in 28 days meets the ready biodegradability criterion (>60%). In some cases, insufficient sampling points were included in the tests to determine whether or not the 10-day window was met and thus are insufficient to demonstrate ready biodegradability. When the 10-day window was not met or less than 60% biodegradation was observed in 28 days, it is likely that the aliphatic acids tested were not fully in solution.
- Executive summary:
Aliphatic Acids category members are readily biodegradable and are not expected to bioaccumulate.
