Description of key information

Acute toxicity of propylene glycol butyl ether was tested with Selenastrum capricornutum following OECD guideline 201.

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
560 mg/L

Additional information

The EC50 value after 96 hours of exposure was > 1000 mg/l with a NOEC of 560 mg/l.

These results indicate that PnB is not toxic to freshwater algae species.
