Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Read-across was used. Hypothesis for the analogue approach: see files attached under section 13 assessment reports Read Across Justification. Test for source substance to biodegradation in water was performed according to OECD 301B and compliant with GLP.

BOD5 / COD results
- Results with reference substance:
- Points of degradation plot (reference substance):
46.4% degradation after 7 d
57% degradation after 9 d

Applicant's summary and conclusion
- Interpretation of results:
- other: not readily biodegradable
- Conclusions:
- The test substance is not readily biodegradable. The test substance (source substance) bis(hydrogenated tallow C16-C18-alkyl)hydroxylamine is a structurally very similar substance to target substance hydroxylamines, di-C16-18 (even numbered) alkyl. It can be reasonably assumed that target substance is also not readily biodegradable.
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.
