Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

EC number: 940-644-8 | CAS number: -
Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: screening tests
- Type of information:
- migrated information: read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Category is coherent for more than 10 endpoints. All members are ready biodegradable and even for some of them anaerobic studies are available and show also ready biodegradability under these conditions.

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- APP category approach based on 8 biodegradation studies allows an estimation of APP-6512 (C10-12) 28-day aerobic biodegradability as equal to 83.2±9.3%.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
