Conclusion on classification
Based on the hazard assessment of O-isopropyl ethylthiocarbamate (IPETC) in section 2.1 and 2.2.in IUCLID 6, available data for the substance and following the “Guidance on Information Requirement and Chemical Safety Assessment R.10, it is concluded that the following phrases needs to be assigned according to the criteria described in Directive 67/548 and in the CLP Regulation:
Directive 67/548 |
N; R50 R52 R53 N;R50/53 N;R51/53 R52/53 N;R59 |
CLP Regulation |
H400 Aquatic. Acute 1 Very toxic to aquatic life H413 Aquatic Chronic 4 May cause long lasting harmful effects to aquatic life H400 Aquatic acute 1, Very toxic to aquatic life H410 Aquatic chronic 1 Very toxic to aquatic life with long lasting effects H411 Aquatic Chronic 2 Toxic to aquatic life with long lasting effects H412 Aquatic Chronic 3 Harmful to aquatic life with long lasting effects EUH059 Ozone, Hazardous to the ozone layer
|
It is concluded that the substance O-isobutyl ethylthiocarbamate (IBETC), meet the criteria to be classified for environmental hazards.
R52/53 Harmful to aquatic organisms,May cause long-term adverse effects in the aquatic environment
H412 Aquatic Chronic 3 Harmful to aquatic life with long lasting effects
