Description of key information

The toxicity to the aquatic environment of 2-(2-methylpropoxy)ethanol was investigated by performing GLP compliant short-term toxicity studies on freshwater aquatic invertebrates and algae in accordance with Annex VII of REACH.

Pseudokirchneriella subcapitata was identified as the most sensitive species based on the outcome of the investigation with a 72 h EC50 of 1920 mg/L. Considering that the lowest L(E)C50 values for 2-(2-methylpropoxy)ethanol is above 1 mg/L, the substance does not meet the criteria for classification as Aquatic Acute 1: H400 in accordance with Regulation (EC) N° 1272/2008.

There is no available data on the chronic toxicity of 2-(2-methylpropoxy)ethanol to the aquatic environment. As the substance is being registered under REACH in the 1-10 tonnage band there is no requirement for information on long-term studies to aquatic species. Therefore the classification of the registered substance for chronic effects is based on the short-term toxicity of 2-(2-methylpropoxy)ethanol to the aquatic environment and it's ready biodegradability.

As the lowest L(E)C50 for 2-(2-methylpropoxy)ethanol is above 100 mg/L, the substance does not meet the criteria for classification for long lasting effects to the aquatic environment in accordance with Regulation (EC) N° 1272/2008.
