Description of key information
Additional information
Acute toxicity studies have been conducted in fish, daphnia, algae and sludge. In summary, reported results indicated no acute toxicity to any of the tested species with EC/LC50 values of 564 mg/L in fish (96 hr), >1000 mg/L in daphnia (48 hr),>1000 mg/l for microorganisms (30 min) and an ErC50 of 592 mg/ for algae (72 hr). Tripropylene glycol n-butyl ether (TPnB) is classified as readily biodegradable and aquatic toxicity data indicate no acute toxicity to aquatic species. The risk assessment shows that the PEC/PNEC ratio is clearly < 1 in surface water, indicating no need for further information or testing.
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.
