Dipropylene glycol methyl ether is highly water soluble (completely miscible) and has a very low potential for adsorption to organic matter. Therefore, the predicted no effect concentration (PNEC) for soil was derived from the PNEC for freshwater using the equilibrium partitioning method. This method is applicable for substances where the toxicity in soils relates to the freely dissolved concentration in pore water. Dipropylene glycol methyl ether is not classified as dangerous for the environment. Dipropylene glycol methyl ether is readily biodegradable and has very low potential for bioaccumulation (log Kow <1). The EC 50s/LC50s - based on acute toxicity data in fish, Daphnia and algae - are higher than 1000 mg/l. Hence, testing of effects on terrestrial organisms can be waived for dipropylene glycol methyl ether.
