EC number: 226-195-4
CAS number: 5324-84-5
In accordance with the criteria set in Annex XIII of the REACH
Regulation (EC) 1907/2006 the substance is not considered PBT or vPvB.
The substance was found to be readily biodegradable following an OECD
301B screening study. The 28 d degradation value was 90.7%, i.e. =>60 %
biodegradation after 28 d. The test item additionally degraded by 60.9%
in 4 d, therefore fulfilling the 10-day window (Flach, F., 2017).
Two partition coefficient tests were performed on the substance [EU
Method A.8: Estimation Method (Solubility Ratio) and EU Method A.8:
(HPLC Method)], giving the following results:
Log Pow= < -2.25 at 20.0°C ± 1.0 °C; EU Method A.8. (Estimation Method
(Solubility Ratio)); C Bär (2018)
Log Pow= < 0.0 at 20.0°C ± 1.0 °C; EU Method A.8. (HPLC Method); C Bär
Log Pow values below 4.5 such as those found above, are not considered
to be highly bioaccumulative and further evaluation is not required, as
described in ECHA's Guidance on Information Requirements and Chemical
Safety Assessment Part C: PBT/vPvB Assessment (v 3.0, June 2017).
The data collated for this substance indicates that the substance does
not meet the criteria for aquatic toxicity:
Invertebrate: 48 h EC50 421 mg/L (Minderhout and Krueger, 2008)
Fish: 96 h NOEC > 100 mg/L (Sipos, 2018)
Freshwater algae: 72 h EC10 (growth rate and yield) >100 mg/L (Schuster,
Not required as the substance is not PBT or vPvB.
