Description of key information

Short-term toxicity testing to fish was conducted with Poecilia reticulata under GLP according to OECD guideline 203.

Key value for chemical safety assessment

LC50 for freshwater fish:
560 mg/L

Additional information

The LC50 (96 hours) of propylene glycol butyl ether was >560 mg/l in a GLP guideline study conducted in Poecilia reticulata. This data is supported by the results of a non-GLP non-guideline study of acceptable quality in Pimephales promelas, showing an LC50 (96 hours) of 1060 mg/l These results indicate that PnB is not toxic to freshwater aquatic species.
