Endpoint:
fish early-life stage toxicity
Type of information:
other: Weight-of-evidence
Adequacy of study:
weight of evidence
Study period:
2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Weight of evidence assessment based on structural analogue
Justification for type of information:
No data is available for "Reaction product of saturated palm kernel fatty acids and oxybispropanediol". The properties of this substance is therefore assessed in a weight of evidence analysis based on existing data on a group of similar compounds. See the attached report.

The following type of substances were included in the assessments: other glycerol esters (both data and QSAR), glycerols, fatty acids and alcohol ethoxylates. The main data sources were: NICNAS, Danish EPA QSAR, the HERA reports for alcohol ethoxylates and fatty acids.

Applicant's summary and conclusion

Validity criteria fulfilled:
not applicable
Conclusions:
As a conservative approach, the conclusion of the weight-of-evidence approach is based on lowest long-term EC10/NOEC for fish of the AE, leading to the value: Long-term toxicity to fish: EC10≥0.213 mg/L.
Executive summary:

“Reaction product of saturated palm kernel fatty acids and oxybispropanediol” is an UVCB substance. Data on long-term toxicity are based on the relevant substance group, Alcohol Ethoxylates (AE)

As a conservative approach, the conclusion of the weight-of-evidence approach is based on lowest long-term EC10/NOEC for fish of the AE, leading to the value: Long-term toxicity to fish: EC10≥0.213 mg/L.
