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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a (Q)SAR model, with limited documentation / justification, but validity of model and reliability of prediction considered adequate based on a generally acknowledged source
- Justification for type of information:
- 1. SOFTWARE
EPISuite 4.1
2. MODEL (incl. version number)
BIOWIN v4.10
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
C(CCCCCCCCCCCCCCC(O)=O)(O)=O
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
For ready biodegradability, BIOWIN is an EPISuite model recommended by ECHA in its practical guide “How to use and report (Q)SARs 3.1”.
5. APPLICABILITY DOMAIN
Not detailed by the software.
6. ADEQUACY OF THE RESULT
The prediction is adequate as the QSAR model is scientifically valid and relevant for the regulatory purpose.

Results and discussion
% Degradation
- Key result
- Parameter:
- probability of ready biodegradability (QSAR/QSPR)
- Remarks on result:
- readily biodegradable based on QSAR/QSPR prediction
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Based on the QSAR prediction, hexadecanedioic acid is expected to be readily biodegradable. This is consistent with the conclusion of the read across approach.
