Key value for chemical safety assessment

Additional information

One study is available for acute toxicity to the marine fish (Cyprinodon variegatus) for Distilled tall oil, maleated.

A GLP-compliant study following a modified OECD guideline 203 is available for distilled tall oil, maleated (AnalyCen Ecotox, 2006). The study utilised WAF techniques. No analytical monitoring of test concentrations was reported. The LL50 for distilled tall oil, maleated, could not be determined as there was no observed mortality at 10 mg/L, the only concentration tested. The NOELR is therefore 10 mg/L.
