Additional information

The acute toxicity of Butyldiethanolamine towards Leucisdus idus was investigated according to German standard DIN 38412 in compliance with GLP (BASF, 1987). Test organisms were exposed to 0 (control), 100, 147, 215, 316, 464 and 464 (pH adjusted) mg/L of the test substance for 96 hours based on nominal test concentrations. The values were not analytically verified, but are assumed to be stable due to the low n-octanol/water partition coefficient (log Kow 0.58), the high water solubility (WS of 10,000 mg/L ), the moderate vapour pressure (VP 1.2 Pa at 25 °C) and the low Henry´s Law Constant (HLC 2.04 x E-5 Pa*m³/mol at 25 °C) of the chemical. One replicate with 10 animals for each test concentration and the control was prepared. As positive control, the reference substance chloroacetamide was used. As final result, LC 50 (96 h) values of > 316 - < 464 mg/L (no pH adjustment) and > 464 mg/L (pH adjusted) were determined. Validity criteria for the reference substance were fulfilled.
