Description of key information

The 72-h EbC50 and 72-h NOEbC were > 1,000 mg/l in Pseudokirchnerella subcapitata (reported as Selenastrum capricornutum)

Key value for chemical safety assessment

EC50 for freshwater algae:
1 000 mg/L
EC10 or NOEC for freshwater algae:
1 000 mg/L

Additional information

One non-GLP compliant guideline study (OECD 201) is available for tripropylene glycol. The 72-h EbC50 value and 72-h NOEbC value is >1,000 mg/l (nominal concentration) in Pseudokirchnerella subcapitata (reported as Selenastrum capricornutum) (OECD, 1994). These values are used in the assessment.
