Description of key information
No toxicological effects on microorganisms are expected up to the limit of water solubility.
Key value for chemical safety assessment
Additional information
Two studies investigating the short-term toxicity of Fatty acids, C18-unsaturated, dimers (CAS No. 61788-89-4) to Pseudomonas putida are available. The first study, a static GLP cell multiplication inhibition test according or equivalent to ISO 10712 showed no effect on the growth of Pseudomonas putida at the tested WAF loading rates after 16 hours (EL10/ EL50 > 10000 mg/L, NOELR ≥ 10000 mg/L) (Sewell, 1997). The second test, a GLP study (no guideline mentioned), included an assessment of acute toxicity of the test substance on cell multiplication of a pure culture of Pseudomonas putida bacteria. After 18 hours no inhibition of the growth of Pseudomonas putida was observed and an EC50 (18 h ) > 3500 mg/L (nominal) was stated.
Thus, it can be concluded that no toxicological effects on microorganisms are expected up to 10000 mg/L of Fatty acids, C18-unsaturated, dimers (CAS No. 61788-89-4).
