Description of key information
Expert Judgement
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a simulation testing on ultimate degradation in surface water, the study does not need to be performed if the substance is ready biodegradable.
Propan-2-ol (Isopropyl alcohol) and Butan-1-ol (Butyl alcohol) are both reagents used in the manufacture of Reaction mass of O-isopropyl ethyl thiocarbamate and n-butanol and propan-2-ol.Therefore, the Biodegradation in water of Propan-2-ol (Isopropyl alcohol)and Butan-1-ol (Butyl alcohol) need to be considered in the assessment of Reaction mass of O-isopropyl ethyl thiocarbamate and n-butanol and propan-2-ol .
The results suggest that Propan-2-ol (Isopropyl alcohol) and Butan-1-ol (Butyl alcohol) are readily biodegradable and therefore IPETC/O-isopropyl ethylthiocarbamate will be readily biodegradable and it is not expected to persist in the environment.
As IPETC/O-isopropyl ethylthiocarbamate is ready biodegradable a ready biodegradability study does not need to be conducted.
Therefore testing for Biodegradation in water does not need to be performed.
Key value for chemical safety assessment
