Description of key information

Substance: 2-(2-(2-methoxyethoxy)ethoxy)ethanol: Leuciscus idus: 96hr LC0>10000mg/l

Substance: tetramethylglycol Pimephales promelas: 96hr LC0>20000mg/l, LC100<40000mg/l. Fish embryo toxicity test, 96hr NOEC=2080mg/L.

QSAR predicts decreasing toxicity with increasing molecular weight within the homologous series.

LC50 is set at the highest NOEC available for the lowest molecular weight component of the mult-constituent substance. This is a very conservative approach but sufficient to meet the data needs for the end point and for classification purposes.

Key value for chemical safety assessment
