PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Dipropylene glycol n-butyl ether does not have PBT or vPvB Properties.
Dipropylene glycol n-butyl ether meets the criteria for ready biodegradation in the OECD 301A and 301E tests indicating substantial mineralization of dipropylene glycol n-butyl ether. The test substance does not fulfill the criteria for persistence as outlined in Annex XIII of the REACH legislation of December 2006.
Dipropylene glycol n-butyl ether has a low log Kow (log Kow = 1.52) and is readily biodegradable, which indicates that dipropylene glycol n-butyl 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 n-butyl ether presents a low toxicity hazard to aquatic species. All EC50/LC50 values (fish, daphnia and algae) are > 100 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.
