Description of key information
Additional information
Tripropylene glycol methyl ether is not classified as dangerous for the environment. Tripropylene glycol methyl ether is readily biodegradable and has very low potential for bioaccumulation (log Kow <1). Acute toxicity studies have been conducted in fish and daphnia. The toxicity to algae has been evaluated by QSAR approach. EC50s/LC50s determined for the three trophic levels indicated a very low hazard of tripropylene glycol methyl ether, as EC/LC50 exceed 1000 mg/L in daphnia (48 hr), fish (96 hours) and algae (3 days). Tripropylene glycol methyl ether induced 75 % growth stimulation of the industrial sludge at the highest dose tested, therefore the NOEC is 2000 mg/L. Therefore it can be considered as non-hazardous for the environment. According to REACH Annex IX requirements, long-term toxicity testing shall only be considered when the chemical safety assessment indicates the need for further investigations. Hence, long-term testing in fish can be waived for tripropylene glycol methyl ether.
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.
