Description of key information

The 21d-NOEC on daphnids with the structurally related substance D-Glucitol (Sorbitol), propoxylated (CAS 52625-13-5) in a OECD 211 guideline study was determined to be 10 mg/L (nominal) for the endpoint mortality.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
10 mg/L

Additional information

No data on the chronic toxicity of the test substance on aquatic invertebrates are available. However, the chronic toxicity of the structurally related substance D-Glucitol (Sorbitol), propoxylated (CAS 52625-13-5) was investigated in an OECD 211 guideline study. In this study, the NOEC (21d) on the mortality of Daphnia magna was determined to be 10 mg/L (Bayer 1357 A/05 D, 2005) related to the endpoint mortality. As the endpoint is not based on reproduction the NOEC is not considered for PNEC derivation. This result is considered to be adaptable for the test substance due to the structural similarities of both molecules.

An in-depth justification for the read-across/grouping of polyol substances is currently under development and will be submitted as soon as it becomes available.
