Additional information
Conclusion on classification
Trimethylolpropanepoly(oxypropylene)triamine needs to be classified for the environment based on the CLP classification and labelling criteria.
Acute (short-term) aquatic hazard
Based on available acute toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is > 1 mg/L and the substance needs thus not to be classified for acute aquatic hazard.
Chronic (long-term) aquatic hazard
Based on available acute toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is between 1 and 10 mg/L and the substance is considered not rapidly degradable. Chronic category 2 should thus be assigned with hazard statement H411 (Toxic to aquatic life with long lasting effects), although the substance has no potential for bioaccumulation (Log Kow = -1.13).
