PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Dipropylene glycol methyl ether does not have PBT or vPvB Properties.

Dipropylene glycol methyl ether (DPGME) meets the criteria for ready biodegradation passing the 10 day window in an OECD 301F. Degradation based on oxygen consumption reached 75% after 10 days, while 79% degradation after 28 days. The formation of CO2 reached 76% CO2 indicating extensive mineralisation of dipropylene glycol methyl ether. The test substance does not fulfill the criteria for persistency as outlined in Annex XIII of the REACH legislation of December 2006.

Dipropylene glycol methyl ether has a low log Kow (log Kow < 1) and is readily biodegradable, which indicates that dipropylene glycol methyl ether offers little potential for bioconcentration in aquatic organisms. Therefore it does not fulfill the criteria for bioaccumulation as outlined in Annex XIII of REACH legislation of December 2006.

Measured aquatic toxicity data indicate that dipropylene glycol methyl ether presents a low toxicity hazard to aquatic species. All EC50/LC50 values (fish, daphnia and algae) are > 1000 mg/l.
