Additional information
Acute studies are available for fish, invertebrates and algae. The EL50 value for Acartia tonsa was 56 mg/L and the EL50 value for Skeletonema costatum was 24 mg/L. No effects were seen at 10 mg/L in a limit test for Cyprinodon variegatus.
Conclusion on classification
Under CLP legislation Distilled tall oil, maleated is assigned the classification Chronic Category 3.
Ecotoxicity results are available for fish, aquatic invertebrates and algae. The lowest EL50 value available for Distilled tall oil, maleated is 24 mg/L for algae, the LL50 for invertebrates is 56 mg/L. In a 96-hour acute toxicity test with fish no effects were observed at 10 mg/L WAF, the only test concentration. As these results are >1 mg/L no acute environmental classification is assigned to Distilled tall oil, maleated. A chronic environmental classification is assigned to Distilled tall oil, maleated as these results are >10 and ≤100 mg/L and Distilled tall oil, maleated is not readily biodegradable.
Under the DSD regulation Distilled tall oil, maleated is assigned a classification of R52 -53.
No acute classification is assigned as the lowest EL50 value is >1 mg/L. A chronic environmental classification is assigned to Distilled tall oil, maleated as the lowest EL50 value is >10 and ≤100 mg/L and Distilled tall oil, maleated is not readily biodegradable.
.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
