Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

For Polyol IXOL M125 the base set data are available, including a respiration inhibition study with activated sludge.

A guideline study for short-term toxicity is available for freshwater fish. The critical acute effect concentration forPolyol IXOL M125 is a 96-h LC50 value of >1,000 mg/L in guppy (Poecilia reticulata) (Solvay Duphar B.V., 1992b), this value will be used in the assessment.

For invertebrates short-term toxicity a guideline study is available for Daphnia magna. The critical effect concentration for Polyol IXOL M125 is a 48-h EC50 value of >1,000 mg/L (Solvay Duphar B.V., 1992c), this value will be used in the assessment.

A growth inhibition guideline study is available for freshwater algae. The critical effect concentrations for Polyol IXOL M125 are a 72-h EC50 value of >1,000 mg/L and a 72-h NOEC of 500 mg/L in Pseudokirchneriella subcapitata ( tested as: Selenastrum capricornutum) (Solvay Duphar B.V., 1992d), these values will be used in the assessment.

Long-term studies with fish and invertebrates are not available.

For the toxicity of microorganisms a respiration inhibition guideline study with domestic activated sludge is available. The critical effect concentration for Polyol IXOL M125 is a 3-h EC50 value of >100 mg/L (ECT Oekotoxikologie GmbH, 2011), the 3-h NOEC value will be used in the assessment.

Studies with terrestrial organisms are not available.

Conclusion on classification

Based on all available data for fish, aquatic invertebrates and algae, according to Directive 67/48/EEC Polyol IXOL M125 needs not to be classified as all acute effect concentrations are >1,000 mg/L. Although Polyol IXOL M125 is not readily biodegradable, the substance is not expected to bioaccumulate as the log Kow ranges from 0 to 3.0.

According to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008, Polyol IXOL M125 does need not to be classified for the environment for the same reasons as stated above.
