PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Tripropylene glycol methyl ether does not have PBT or vPvB Properties.
Tripropylene glycol methyl ether (TPGME) meets the criteria for ready biodegradation passing the 10 day window in an OECD 301 F. Degradation based on oxygen consumption reached 60 % after 10 days. The formation of CO2reached 51% indicating substantial mineralisation of tripropylene glycol methyl ether.
Tripropylene glycol methyl ether has a low log Kow (log Kow = 0.08) and is readily biodegradable, which indicates that tripropylene glycol methyl ether offers little potential for bioconcentration in aquatic organisms, and will not bioaccumulate.
Measured aquatic toxicity data indicate that tripropylene glycol methyl ether presents a low toxicity hazard to aquatic species. All EC50/LC50 values (fish, daphnia and algae) are > 1000 mg/l.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
