Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
biodegradation in water: ready biodegradability
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016-03-19 till 2016-04-15
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
without GLP
Qualifier:
according to guideline
Guideline:
OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test)
Version / remarks:
adopted July 17, 1992
GLP compliance:
no
Remarks:
The substance is known to be not readily biodegradable. Therefore a non-GLP study was adequate to prove the poor biodegradability.
Oxygen conditions:
aerobic
Inoculum or test system:
activated sludge, domestic, non-adapted
Duration of test (contact time):
28 d
Initial conc.:
41 mg/L
Based on:
test mat.
Preliminary study:
Result of the preliminary study:
The biodegradation of the test item (2 replicates) does not reach the 10 % level (beginning of biodegradation) until test end. The mean biodegradation on day 28 was 6 %.
Key result
Parameter:
other: BOD
Value:
ca. 6
Sampling time:
28 d
Remarks on result:
other: not readily biodegradable
Details on results:
not readily biodegradable
Results with reference substance:
no reference substance used for limit test
Validity criteria fulfilled:
yes
Interpretation of results:
not readily biodegradable
Conclusions:
The test item is classified as not readily biodegradable within 28 days.
