Remarks:
Migrated informationCriteria used for interpretation of results: EU
Conclusions:
The LD50 of Fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts is greater than 2000 mg/kg bw by the oral route in the rat.According to the criteria for classification, packaging and labelling of dangerous substances and preparations in accordance with EEC Directives 67/548, 2001/59 and 99/45, the test item of Fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts cannot be classified because it cannot be determined whether the LC50 falls in Category IV (< 2000 mg/kg) or outside of the category.In accordance with the Globally Harmonised System (Regulation (EC) No. 1272/2008) the test item cannot be classified because it cannot be determined whether the LC50 falls in Category V (< 5000 mg/kg) or outside of the category.
Executive summary:

In an acute oral toxicity study, a single dose fatty acids, tall oil, oligomeric reaction products with maleic anhydride and rosin, calcium magnesium zinc salts was administered via gavage to six female rats were at a concentration of 2000 mg/kg. One animal died prior to study termination. The only effects seen in the surviving animals were decreased spontaneous activity and piloerection in one animal at 24.5 h post dose. Body weight gain was normal and there were no macroscopic abnormalities at post mortem on completion of the study.The acute oral LD50 in this study was >2000 mg/kg bw for female rats.
