Description of key information

1-(dimethylamino)propan-2-ol is acutely harmful to aquatic organisms

Key value for chemical safety assessment

EC50 for freshwater algae:
77.4 mg/L
EC10 or NOEC for freshwater algae:
42 mg/L

Additional information

In a guideline test according to German industrial standard DIN 38412, part L9 on the toxicity of 1-(dimethylamino)propan-2 -ol to Desmodesmus subspicatus (reported as Scenedesmus subspicatus) an ErC50 (72 h) of 77.4 mg/L was detected (not pH adjusted; BASF AG, 1989). The 72 -h ErC10 was 42 mg/L (not pH-adjusted). The inhibition of algal growth by 1-(dimethylamino)propan-2-ol was reduced by adjusting the pH in the test system. The test item concentrations were not analytically verified, but are assumed to be stable.
