EC number: 442-730-6
CAS number: 35132-93-5
Hydrolysis: waiving according to Annex XI of Regulation (EC) No.
1907/2006 (technically not feasible)
Ready Biodegradation: not readily biodegradable in the 10d-window
and after 28 days; percentage biodegradation was 39% after 28 days
Bioaccumulation: log BCF of 0.5, estimated with BCFBAF model (v.
Adsorption /desorption: waiving according to Annex VIII, column 2
of Regulation (EC) No. 1907/2006
A reliable study is available on the ready biodegradability of the
submission substance (RL2). The study was performed acc. to OECD 301B /
CO2 Evolution (Modified Sturm Test) and in compliance with GLP. The pass
level of a biodegradation > 60 % could not be reached in the 10d-window.
The mean biodegradation of the test item came up to 39% after 28
days. Consequently, the test substance must be regarded not readily
biodegradable in the 10d-window and after 28 days. The study was
considered adequate and reliable for the evaluation of the ready
biodegradability of the submission substance.
Data on bioaccumulation is only required according to Annex IX of
Regulation (EC) No 1907/2006. However, a valid QSAR model was applied to
estimate BCF for the PBT/vPvB assessment.
The log BCF was estimated with the Meylan et al. method of the BCFBAF
software (v. 3.01), a valid well-documented model. The log BCF was
estimated by BCFBAF to be 0.5 (RL2). In conclusion, the submission
substance is not expected to bioaccumulate in organisms.
Transportation and distribution
Waiving according to Annex VIII, column 2 of Regulation (EC) No.
1907/2006: The study does not need to be conducted if based on the
physicochemical properties the substance can be expected to have a low
potential for adsorption (e.g. the substance has a low octanol water
