Additional information

Conclusion on classification

The information concerning the aquatic toxicity of DIMETHYLISOPROPYLAMINE (DMIPA)

are summarized hereafter:

Acute toxicity to fish: LC50_96h = 36.1 mg/L

Acute toxicity to daphnia: EC50_48h = 38.4 mg/L

Long-term toxicity to daphnia: NOEC = 1.73 mg/L

Toxicity to algae: ErC50_72h = 5.38 mg/L and ErC10_72h = 0.93 mg/L

DMIPA is not readily biodegradable and has a log Kow < 1.

Based on these results, here is the classification for this substance:

Dangerous substance directive: R51/53

Classification Labelling & Packaging: H411 (Chronic 2)
