Description of key information

The analogue “Fatty acid, tall-oil, reaction products with diethylenetriamine, maleic anhydride, tetraethylenepentamine” caused 0.5% mortality to zebra fish after 96-hours of exposure at the nominal product concentration of 100 mg/L in a static test (Chemservice 2010b). 
The NOEC, LOEC and LC50 values after 96 h, calculated based on the nominal concentration, were assessed to be as follows:
96 h NOEC: 100.0 mg/L
96 h LOEC: > 100.0 mg/L
96 h LC50: > 100.0 mg/L
96 h LC50: > 100.0 mg/L

Key value for chemical safety assessment

Additional information

The LC50 (>100 mg/L as loading rate) is derived for an analogue substance. The rationale for read across can be found in chapter 13
