Description of key information

No biodegradation studies in soil are available for dipropylene glycol methyl ether.

Key value for chemical safety assessment

Additional information

Dipropylene glycol methyl ether is readily biodegradable in freshwater with a low potential for adsorption to soil

(log Kow of 0.006). According to REACH Annex IX requirements, soil simulation testing shall only be considered for substances with a high potential for adsorption to sediment and need not be conducted if the substance is readily biodegradable, hence a simulation test in soil can be waived for dipropylene glycol methyl ether.
